These are the fibrous roots, and the number of such roots keeps on increasing with the growth of. No fibers are present enclosing these small bundles. As a lifetime disorder, ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that affects quality of life and also demands long-term interventions. This ginger is more pungent but lacks the aroma of Jamaica ginger. Endodermis differentiates from the innermost periblem cells. In certain loci, where the vascular bundles develop, these cells are elongated with tapered ends and appear similar to the fusiform initials with an average of 62.34 ^m length and 8.12 ^m width in mature stages. Roots always develop just below the nodal region. G. Cytoplasmic condensation. The second type is the actively dividing ground parenchyma. It is covered with a brownish skin that may either be thick or thin, depending upon whether the plant was harvested when it was mature or young. Subsequently the surrounding cells also enlarge in size, showing cytoplasmic and nuclear disconfigurations (see Figure 2.7E, F). This led to the suggestion that the cells at the tip of the root body go into quiescence because of the dearth of sufficient metabolites (Pillai et al., 1961). The protoderm—periblem complex is located outside the plerome and is composed of a single tier of cells. inflicting considerable quantitative and qualitative losses. These cells can be distinguished from the surrounding cells by their meristem-atic activity, stainability, and size of the nucleus. There are four stages involved in its development: initiation, differentiation, secretion, and quiescence. The rhizome (underground part of the stem) is the part commonly used as a spice. Specialists in Science Images. The flank meristem is situated on either side of the central mother zone. 1 lb Fresh Organic Ginger Root/Rhizome - Grown on our Herb Farm in Mississippi - USDA Certified Organic PJHerbal. During vascular differentiation a few cells of this meristem develop into procambium. Initiation and differentiation: In shoot apex, the meristematic cells are arranged in tiers. The main axis (mother rhizome) and the subsequent branches (primaries) have 6 to 15 nodes. The perennial rhizome of the ginger plant is a specialized segmented stem structure that grows horizontally just under the soil surface. These cells are distinct in the dormant or early active rhizome apex and constitute latitudinal growth meristem. They are spherical and densely stainable. Ginger plant (Zingiber officinale Rosco) is belonging to the family Zingiberaceae.It is one of the world’s most important spices and produces a pungent, aromatic rhizome. [The] so-called white or Jamaica ginger is produced by carefully peeling the fresh rhizomes so that only the epidermis is removed, the cells immediately beneath the epidermis being the richest in volatile oil and resin. MATERIALS AND METHODS Source of plant material Fresh rhizomes of ginger were obtained in January 2019 from Ayama Daily Market in Abua/Odual Local Govern-ment Area in Rivers State. In botany and dendrology, a rhizome (, from Ancient Greek: rhízōma "mass of roots", from rhizóō "cause to strike root") is a modified subterranean plant stem that sends out roots and shoots from its nodes. The pattern of rhizome branching is illustrated in Figure 2.6. The flesh of the ginger rhizome can be yellow, white or red in color, depending upon the variety. Pinyin name(s): jiang; sheng jiang (fresh rhizome); gan jiang (dried rhizome); pao jiang (prepared rhizome); jiang pi (peel), The odor of ginger [rhizome] is aromatic and penetrating, the taste spicy, pungent, hot, and biting. administered ginger rhizome powder in daily dosages of 50 and 100 mg/kg for 20 days, did not demonstrate any changes in morphology or weight of testes compared to c ontrol rats. It is the oldest rhizome widely domesticated as a spice. Cells of the pr2 zone show dense staining. dried ginger rhizomes afforded, moisture content 72.63 ±0.09%, 10.03±0.09%, total ash 2.50 ±0.06%, 7.30±0.10%, acid insoluble ash 0.57±0.03%, 2.03±0.09%, and water soluble ash 1.23±0.03%, 3.87±0.09% respectively. It sometimes begins to grow when kept in a damp atmosphere. Infected rhizome of ginger showing water soaked lesion were collected from farmers’ field of Ri-Bhoi district in Meghalaya. After storage, the residual … The following discussion is based on the studies of the above workers. tillers. There are 4 to 48 fibers or occasionally more. The large cell is the sieve cell. Zones pr1 and pr2 show denser histological staining than cr and rr zones. It also contains 50% starch, 2 to 3 % proteins and a small amount of sugar. In the rhizome apices it is also associated with the initiation of the axillary buds. (a) Germinating bud appears from the eye of the stem tuber. The newly harvested ginger rhizome is yellow; it is called popularly "tender ginger" or "fresh ginger." It belongs to the family Zingberaceae cultivated all over tropical and subtropical countries. Chronic toxicity studies have not raised suspicion of other organ changes. B. O. Desalu 1 Then the next cell (in acropetal order) becomes differentiated into an oil cell and starts elimination of its contents followed by lysis. Fig 2: Plant of Amomum compactum Soland ex. Macroscopic Characteristics The ginger plant, Zingiber officinale, has a biennial or perennial, creeping rhizome, and an annual stem, which rises two or three feet in height, is solid, cylindrical, erect, and enclosed in an imbricated membranous sheathing. The ducts are initiated by the separation of a group of densely stained meristematic cells through dissolution of the middle lamella. These stages occur between 1500 and 3000 ^m from the apex. Adequate tests on reproductive toxicity , Pith cells differentiate in the inner axial zone (rr). Some cells of pr1 and pr2 (see Figure 2.7) showed dense stainability for C-RNA (cytoplasmic RNA). This is the first formed rhizome knob and is often called the mother rhizome. Each vascular bundle consists of phloem, composed of small thin-walled polygonal cells with well-marked sieve tubes and xylem composed of one to nine vessels with annular, spiral or reticulate thickenings. It gradually merges with the zone outside, the meristematic zone. AHPA recognizes other valuable resources exist regarding the identity of Zingiber officinale. Procambial differentiation: The peripheral or flank meristem divides periclinally and produces parenchymal cells. The third type is the secondary thickening meristem (STM), in which fusiform and ray initials are clearly visible. In transection, an endodermoidal layer is also visible during the development (Remashree et al., 1998; Ravindran et al., 1998). Pillai et al. 1. Uses; Benefits; Cautions; Interactions; Other names; References; Uses. In a dormant apex they are thick walled and contain starch grains. From this layer inverted and irregularly distributed groups of xylem and phloem are formed along the intermediate layer. Stationary Phase Stationary phase, i.e. The rhizome is considered the most useful part of the plant. Oil cells are present in the epidermis or just below the epidermis of the leaf, petiole, rhizome, and root. Its traditional uses cover a great variety of complaints including dyspepsia, flatulence and colic, nausea and vomiting, colds and flu, migraine, as well as muscular and rheumatic disorders. An empty cell or cells with distorted cytoplasm appear along the duct lumen. The shoot apex is 91 to 112 ^m in width and 134 to 167 ^m in height. 1 Bulletin of Health, Science and Technology BHST ISSN 0858-7531 Volume 14, Number 1, 2016 : 01-09 MICROSCOPIC INVESTIGATION OF CURCUMA PETIOLATA ROXB. Quiescence and secretory stages are visible from the third month onward after planting. The cortical cells are heavily loaded with starch grains. The Jamaica or white ginger is white or yellowish-white on the outside. The part of ginger that's used most often is the root. In stage one (dormant apex), the shoot apex lies in a shallow depression, the apex measures 116 to 214 ^m by 45 to 70 ^m. The first sieve tube element can be distinguished at a distance of 720 to 920 ^m from the shoot apex. Ginger is readily available as a powdered spice, fresh in produce departments and in pill form in the vitamin aisle. Observations on the microscopic studies of the fresh rhizomes of turmeric and ginger revealed possession of oil duct and spiral xylem vessels. Currently, the trait of vascular bundles collateral in a ring in endodermis is regarded as a basis for the identification of ginger ( Chinese Pharmacopoeia Commission, 2015 ); based on our research, these vascular bundles are not present in the endodermis, but rather in the pericycle. The ontogeny of ginger was studied by Shah and Raju (1975b), Remashree et al. In the study conducted by Rosangkima et al., (2018), F.oxysporum, F. solani and Plectos-phaerella cucumerina were also iso-lated and identified from soft rot diseased ginger rhizomes. After confirming for the presence of fungal spores, isolation was done by tissue segment method … Source: United States Dispensatory (1918) [4], Zingiber officinale The median longisection of this group of cells is in the shape of a cup with the rim forward. The outer corpus cells show peripheral divisions. The above characteristics show their state of rest and are called the quiescent center. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). Zingiber officinale Roscoe   Zingiberaceae   Figure 2.7 Ontogeny of oil cell in ginger: lysigenous development. Lane Assignments Lanes, from left to right (Track, Volume, Sample): Reference Sample(s) Reference: Individually dissolve 0.5 mg each of 6-gingerol and 6-shogaol in 1 mL of methanol. 2. These variations were presented in a comparative study of ginger and three other species (Ravindran et al., 1998). Ginger is called by different names in different parts of the world such as Zingiberis rhizome, Shen jiany, Cochin, Asia ginger, Africa ginger and Jamaican ginger (Peter 2000). The shoot apical organization and acropetal differentiation of procambial strands are closely related to the phyllotaxy. Many scattered, collateral, closed vascular bundles are present, of which the greater number is seen in the inner cortical zone. The rhizome of ginger is buff colored with longitudinal striations or is fibrous with no cork. In recent years quality of this ginger has improved. Ginger translation in English-Kinyarwanda dictionary. Between these fusiform initials, some cells show transverse divisions to form ray initials. Sieve tube: Phloem cells originate from a group of actively dividing procambial cells of PTM. Extractive values for ginger were recorded as alcohol 2.7% and water 2.1%, fresh and dried ginger rhizomes afforded, moisture content 72.63 ±0.09%, 10.03±0.09%, total ash 2.50 ±0.06%, 7.30±0.10%, acid insoluble ash 0.57±0.03%, 2.03±0.09%, and water soluble ash 1.23±0.03%, 3.87±0.09% respectively. In ginger, development of sieve tube is pycnotic, similar to the second type of nuclear degeneration reported by Esau (1969) and Evert (1984). Macroscopic & Microscopic Molecular-associated Treatments of Monosodium Glutamate-induced Uterine Fibroid via Aqueous Extract of Ginger Rhizomes: A Study on Adult Female Wistar Rats A. J. Olanrewaju 1,2*, J. O. Owolabi 1, S. Y. Olatunji 1, E. I. Oribamise 1, O. I. Omotuyi 3 and A. Rhizome enlargement in ginger is by the activity of three meristematic zones. In the rhizome, oil cell initials are present in the meristematic region. The meristematic activity of the PTM is responsible for the initial increase in the width of the cortex. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). Identification: Compare result with reference images. 1. Such cells act as the oil cell mother cell. Anatomical Features of Ginger in Comparison with Related Taxa. The axillary bud meristem is first discernible in the axillary position on adaxial sides of the third leaf primordium from the apical meristem as a distinct zone by the stainability of the constituent cells and multiplane division of the cells in the concerned peripheral meristem sectors. The cells outer and inner to the cambial layer become filled with starch grains. The lysigenous type of duct formation is more frequent in the meristematic region, but occurs in mature parts too. Rhizome definition, a rootlike subterranean stem, commonly horizontal in position, that usually produces roots below and sends up shoots progressively from the upper surface. Standardized common name (English): ginger   In the present study, various concentrations of extract prepared from Z. zerumbet were screened for its activity against Pythium myriotylum. This character combined with the response of these cells to stains such as pyronin-methyl green indicates that these cells are in a state of comparative repose and hence are not synthesizing nucleic acids (Pillai et al., 1961). According to Stirling (2009), the major causes of post-harvest losses of ginger rhizome is decay or wet rot caused by Primary finger (first-order branch). The outermost three to five rows of cortical cells are not rich in oil contents. During development, a procambial cell elongates and becomes thick walled with cytoplasm and a prominent nucleus; this is the sieve tube mother cell. The cultivation of ginger commenced in Nigeria in 1927 and the locations include Southern Zaria, Jemma Federated districts and neighboring parts of Plateau but today, ginger is cultivated nationwide (Okwuowulu, 1997). Ginger is a rhizome originally from Indochina that has a strong, spicy flavor which people use to flavor dishes.In cooking, ginger adds an exotic touch that’s characteristic of Asian cuisine.People have also used ginger since ancient times for health benefits, pain relief and other health problems as well. a group of oil cell initials (see Figure 2.7B—E). The plant has narrow; lanceolate to linear-lanceolate, The apex of stage six is prominently dome shaped having a width of 169 to 200 ^m and height of 87 to 96 ^m. At the early stage of development, the slime body is present in the sieve tube, which appears to be amorphous but homogeneous. pylori Inhibition and Anti-Oxidative Mechanism. It is delimited by the shell zone on the rhizome apices, which appears as an arc of narrow cells in median longitudinal section. Ginger is the dried rhizome of Zingiber officinale, Roscoe (N.O. This is in direct connection with the vascular ring situated beneath the endo-dermoidal layer. Outside the plerome dome all cells of the periblem exhibit T-divisions initially but later in development show anticlinal divisions, and the endodermis is differentiated at that time. The collateral differentiation of phloem and xylem with parenchymal bundle sheaths becomes distinct after an intermediate stage of random differentiation of the bundles. Cytohistological zonation based on staining affinity is not observed at any stage. Such ‘rhizomes are called sobole rhizomes. Such groups of cells can be identified by the plane of cell division. As a rule there is no secondary growth in monocots. ii. Beneath the epidermis is a brownish, resinous, almost homy cortical portion. The distal few nodes of the rhizome have sheath leaves. 2016, 14 (1): 01-09 Phadungcharoen et al. In the underground stem the nodes have scale leaves that ensheath and protect the axillary buds. (Source: Shah and Raju, 1975a.). Unlike in many monocots, in ginger rhizome there is a special meristematic layer along with the endodermoidal layer, and this layer consists of cambium-like cells. C. Two main axes developing from the seed rhizome, and their subsequent branches developing in the same plane. Maton. Ginger rhizome, known as Rhizoma Zingiberis in pharmacy is used in several traditional systems of medicine, including Traditional Chinese Medicine, Ayurveda and Western herbal medicine. The aim of this study was to review the chemical composition and biological activities of Z. officinale (ginger) essential oil. Outer corpus cells are vertically elongated. (Note: Cork tissue develops after the harvest and during storing. Source: Encyclopedia of Life http://eol.org/data_objects/24891510[9], Ginger Flower (Zingiber officinale) (1998). The vascular bundles are collateral, closed, and scattered in the ground parenchyma. The peripheral zone (pr1) is concerned with the initiation of the next leaf primor-, Figure 2.8 Ontogeny of shoot apex: (A) dormant rhizome with stage 1 root apices; (B) rhizome with stage 2 shoot apex; (C) rhizome with stages 5, 6, and 7 root apices; (D) aerial apex showing topographical zonation; (E) rhizome apex showing topographical zonation. 61. Other Notes Images presented in this entry are examples and are not intended to be used as basis for setting specifications for quality control purposes. No green or reddish fluorescent zones are seen at Rf ~ 0.07 and 0.20 (Katsumada galangal semen (Alpinia katsumadai)). Anticlinal and periclinal divisions of these cells result in. The vascular system in the underground rhizome of Alpinia speciosa L. (Zingiberaceae) is seen to be arranged in three distinct zones. The flower-stalk rises by the side of the stem from six inches to a foot, and, like it, is clothed with oval acuminate sheaths; but it is without leaves, and terminates in an oval, obtuse bracteal, imbricated spike. The percentage of cell division is much lower in the quiescent center compared to the meristematic zone. The procambial cells and the ground meristem cells divide and parenchyma as well as vascular tissues add thickness to the newly enhanced axillary bud. Later Tomlinson (1956) supplemented the information and filled in the gaps. (1961). Rhizomes are also called creeping rootstalks or just rootstalks. The development of leaves and scale leaves that encircle the shoot apex in ginger rhizomes is in a clockwise direction. Oil cell mother cell. The It is sliced before drying. Macroscopic Characteristics The main rhizome (round turmeric) is ovate or pear-shaped, up to 4 cm. identification using molecular character-ization technique. They found that the structural organization of ginger root apex differs from that of other taxa (such as Curcuma, Elettaria, and Hedych-ium). Mother rhizome. A biochemical zonation is present at pr2 that shows deep staining for DNA. Figure 6.2 The rhizome of ginger. Additional weak zones may be present. The stele that forms the bulk of the rhizome consists of parenchymal cells similar to those of the cortex, with starch grains and oil globules and a large number of irregularly scattered vascular bundles. The main axis developing from the apical bud, which is the first developing branch, has 7 to 15 nodes, which later. Under white light the chromatogram of the test solution shows three violet zones at Rf ~ 0.24, Rf ~ 0.27, and Rf ~ 0.29 corresponding to reference substance 6-gingerol, 8-gingerol and 10-gingerol. Rhizomes of ginger are valuable all over the world not only as a spice but also as herbal medicine. The secretion fills the duct in young stages, but the quantity becomes reduced gradually, and finally the ducts appear empty. In longisection the quiescent center resembles an inverted cup. Oct 2, 2016 - Science Image of Ginger rhizome showing oil globules from PS MicroGraphs. The development of a new rhizome is by the enhancement of a dormant axillary bud, which acts just like the main shoot apex. Cytophysiological Organization of Root Tip. (1998), and Ravindran et al. In this stage the cells adjacent to the duct become storage cells, containing numerous starch grains and large vacuoles. Uses: Ginger is used as a carminative and aromatic stimulant. The root apical organization in ginger together with many other zingiberaceous taxa was first reported by Pillai et al. Adventitious roots and lateral growing points emerge from the nodes of the rhizome stem. Ginger rhizome with fresh shoot Young ginger shoots and rhizome Used plant part. Ayurvedic name(s): ardraka (fresh rhizome); shunthi (dried rhizome)   The transection of a fresh, unpeeled rhizome is almost circular or oval, about 2 cm in diameter, with the outline almost regular. 4. 5 out of 5 stars (800) 800 reviews $ 19.95. The losses estimated were to the tune of 50 per cent in the country (Joshi and Sharma, 1982). Further separation of the bordering cells along the radial wall leads to widening of the duct lumen. A distinct continuous layer of epidermis is generally present, consisting of a single row of rectangular cells; in some cases, it may be ruptured. These properties gradually diminish, and are ultimately lost, by exposure. Below the zone due to 6-gingerol there are several weak violet zones. (1961) named this meristematic region columellogen. The characteristic flavor of ginger is due to zingerone, shogaols, gingerols, and volatile (essential) oils that comprise up to 3% of ginger on fresh weight basis . The cells arise by the activity of a meristem, which can be easily differentiated from the rest of the region. The meristematic zone: This zone is shaped like an arch surrounding the quiescent center on the sides of the root body. Fig.1: Rhizome of Zingiber zerumbet (L) Smith. is one of the major disease of the ginger (.Zingiber officinalis Rose.) At the early stage of development they lack any apparent slit due to the overlapping of their margins. The pieces are rounder and thinner, and afford when pulverized a beautiful yellowish-white powder. At a lower level in the rhizome from the shoot bud apex, the PTM can still be identified. If more than one branch from the parent rhizome is responsible for the ultimate growth and development of the adult rhizome, the branches of the mature rhizome lie in the same plane (Shah and Raju, 1975a). The rhizome is buff coloured, laterally compressed, bearing pper side, each sometimes having a depressed scar at the apex; the whole rhizomes are about 5-10 cm long, 1.5-3 cm or 4 cm wide and 1-1.5 cm thick, sometimes split longitudinally. Introduction. leaf consists of a leaf sheath, a ligule, and an elliptical—lanceolate blade. The secondary wall thickening in the tracheids of ginger is of two types, scalariform and helical. Later a longitudinal slit is formed through which the shoot tip projects. Scattered within the cortex are numerous oil cells that contain large globules of yellowish-green color. Source: Elan M. Sudberg, Alkemist Laboratories[12], Fiber showing oblique pores when observed at 400x with Acidified Chloral Hydrate Glycerol Solution. A pair of ligules is formed at the junction of leaves and sheath. The rhizome pieces of Z. officinale were washed with tap water to remove soil and were made to 1–2 cm long pieces. Contents. At the same time, the nucleus disintegrates and the cell assumes the features of the enucleated sieve tube element. (1) An inner system of ‘scattered’ vascular bundles which serial cinematography reveals to have an axial pattern conforming to the basic ‘palm’ configuration (a system of upwardly branching leaf traces with interconnections). The present study focuses on the clastogenic effect of ginger rhizome. B. Source: WikiMedia Commons (Venkatx5)[10], Source: United States Dispensatory (1918) [11], Ellipsoidal and irregular starch granules showing one constricted end observed at 400x with Acidified Chloral Hydrate Glycerol Solution. Periblem consists of the initials of the cortex extending from the hypodemis to the endodermis. E. Nuclear disintegration of central cell. Xylem vessels occur in ginger and not in other species. As this tiller grows, its base enlarges into a rhizome. It is found in water grasses (typha). The same pattern of growth is continued for successive branches to form a sympodial growth pattern. Microscopic free-floating species, however, do not have rhizoids at all. The nitrogen source was from Tithonia compost (TC). These axillary branches are plagiotropic and then they quickly show orthotropic growth at their distal region and subsequently become aerial shoots (see Figure 2.5). Similar tracheids are present in Z. macrostachyum, whereas in Z. zerumbet and Z. roseum, only scalariform thickening occurs (Ravindran et al., 1998). Sample Preparation Method Sample: Mix 1 g of powdered sample with 10 mL of methanol and sonicate for 10 minutes, then centrifuge or filter the solutions and use the supernatants / filtrates as test solutions. Ginger (Zingiber officinale) is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice and a folk medicine. 515). A foliage. Tertiary finger (third-order branch). A violet zone at Rf ~0.53 corresponding to 6-shogaol is present. The cells composing this tissue vacuolate earlier than the outer cells of the cortex. The TS shows a light-brown-colored outer border and a central zone 1.2 cm in diameter marked off by a yellowish ring from an intermediate cortical zone. Infected rhizomes and were then brought to laboratory and washed with tap water to remove soil sample and infected portion were then observed microscopically. They measure 30 X 30 to 114 X 48 ^m. Secretion: The differentiated oil cells start a holocrine type of secretion and expel their contents into the duct. The apex at stage three measures 76 to 140 ^m in width, and 53 to 86 ^m in height and is dome shaped. It undergoes a longitudinal unequal division, and the resulting smaller cell gives rise to the companion cell.
