It is delimited by the shell zone on the rhizome apices, which appears as an arc of narrow cells in median longitudinal section. Derivatization reagent: Anisaldehyde reagent Preparation: 170 mL of ice-cooled methanol are mixed with 20 mL of acetic acid, 10 mL of sulfuric acid, and 1 mL of anisaldehyde. Zingiber zerumbet Smith or wild ginger is remarkable for its inherent resistance to Pythium spp., which cause soft rot disease in Zingiber officinale Rosc. In a dormant apex they are thick walled and contain starch grains. It is the oldest rhizome widely domesticated as a spice. Results: In the second week results revealed EMF exposure The rhizomes are carefully dug up with hard picks, washed and dried. The median longisection of this group of cells is in the shape of a cup with the rim forward. 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. Oil cell mother cell. Introduction: Ginger (Zingiber officinale Rosc.) The axillary buds thus originate as a cellular patch in the adaxial side of a leaf or scale leaf of the node. 3. Find the perfect fresh ginger rhizome stock photo. Rhizome rot of ginger incited by Pythium aphanidermatum (Edson.) The following discussion is adapted from Pillai et al. The ontogeny of ginger was studied by Shah and Raju (1975b), Remashree et al. Primary finger (first-order branch). 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. Raju and Shah (1977) studied the root apices of ginger, mango ginger, and turmeric with azure B staining to localize DNA and RNA contents in order to identify the quiescent center. Pith cells differentiate in the inner axial zone (rr). Such cells act as the oil cell mother cell. A few cells toward the flank showed increased concentrations of DNA as evidenced by dense staining. body weight) for 8 weeks as well. The phyllotaxy of the scale leaves on the rhizome and foliage leaves on the aerial stem is distichous, with an angle of divergence of about 180°. It gradually merges with the zone outside, the meristematic zone. Very early in the development of the rhizome, a zone of meristematic cells is formed at the base of a young scale leaf primordium of developing rhizome. becomes an aerial shoot. Many scattered, collateral, closed vascular bundles are present, of which the greater number is seen in the inner cortical zone. Further separation of the bordering cells along the radial wall leads to widening of the duct lumen. Isolation of Fungi from Ginger (Zin-giber officinale)using Blotter Method Fungal pathogens associated with ginger were isolated using standard … In ginger all the underground branches show a negative geotropic response. B—D. The hypodermis arises from the inner layer of the protoderm—periblem initials. A. J. Olanrewaju 1,2*, J. O. Owolabi 1, S. Y. Olatunji 1, E. I. Oribamise 1, O. I. Omotuyi 3 and A. 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 adventitious root primordia become differentiated endogenously from the endoder-moidal layer of the rhizome. (Note: Cork tissue develops after the harvest and during storing. Zingiber officinale (rhizome) HPTLC ID - Anisaldehyde reagent, white RT, Zingiber officinale (rhizome) HPTLC ID - Anisaldehyde reagent, UV 366 nm, From AHPA Botanical Identity References Compendium, High Performance Thin Layer Chromatographic Identification, Köhler, Medizinal-Pflanzen in naturgetreuen Abbildungen und kurzerläuterndemTexte (1887), http://specimens.kew.org/herbarium/K001124208, http://caliban.mpiz-koeln.mpg.de/koehler/INGWER.jpg, http://commons.wikimedia.org/wiki/File:Zingiber_officinale.JPG, http://commons.wikimedia.org/wiki/File:Ginger_Flower_vs.jpg, http://www.botanicalauthentication.org/index.php?title=Zingiber_officinale_(rhizome)&oldid=6995, Encyclopedia of Life http://eol.org/data objects/24891510, About AHPA Botanical Identity References Compendium. groups received Ginger rhizome powder (1.5 g/kg/day. Once the lysogeny of the central cell is completed, the adjacent cells also lyse gradually in a basipetal manner, resulting in the widening of the duct lumen. The rhizome of ginger is buff colored with longitudinal striations or is fibrous with no cork. Upright-growing shoots are produced from the tips of lateral rhizome branches. Ginger, the rhizome of Zingiber officinale, is one of the spices widely used worldwide for various foods and as an herbal medicine [3] . 515). The number of primary branches may be two, three, or four. 5, 1, 2, 5, 10 g/kg body weight and ginger oil (0.625, 1.250 and 2. The differentiation of procambial cells into vascular tissue takes place at different stages of rhizome growth. The increase in size of the phloem element is proportional to the growth of the rhizome. The outer corpus cells show peripheral divisions. A pair of ligules is formed at the junction of leaves and sheath. b. divides more frequently c. have larger nuclei and nucleoli d. vacuolation is absent or not prominent. The meristimatic zone includes the cells of all the structural histogens of the root body. As the phyllotaxy is distichous, this zone is opposite to pr1 in median longisections. Macroscopical Character: i. Colour- Yellow to yellowish brown externally, yellow to yellow orange internally. Some of the cells are distinguishable from the rest by deeper stainability, smaller size, less or no vacuolation, and darkly stained nuclei. tillers. The scattered vascular bundles are developing from the PTM or procambial cells. Figure 2.3 Floral diagram of ginger flower. At an even lower level basipetally in the rhizome axis, additional inner cortical cells are produced by a lateral PTM or procambium in which the resulting cells are radial rows. Within the bud, leaves have imbricate aestivation (Shah and Raju, 1975a). View abstract. Normally, these roots originate from the lateral or opposite side of the axillary bud and scale leaf. In a longisection, the shoot apex is dome shaped with a single tunica layer, below which the central mother cell zone is present. The large bundles are partially or entirely enclosed in a sheath of septate fibers, whereas the smaller bundles are devoid of any fiber. From this layer inverted and irregularly distributed groups of xylem and phloem are formed along the intermediate layer. Any plant of a genus (Zingiber, especially Zingiber officinale) of tropical Asiatic and Polynesian herbs of a family (Zingiberaceae, the ginger family) with pungent aromatic rhizomes used as a condiment and as a stimulant and acarminative. The distal few nodes of the rhizome have sheath leaves. Phytomedicine 2007;14(2-3):123-128. C. Two main axes developing from the seed rhizome, and their subsequent branches developing in the same plane. The width varies from 5.29 to 10.35 ^m, the average being 8.76 ^m (Remashree et al., 1998). However, the rhizome structure of ginger gives evidence of both primary and secondary growth having a well-developed endodermoidal layer and cambium. Two kinds of apices are found in ginger: (1) the apices are low dome and surrounded by either scale leaves or leaf bases, and (2) they are dome shaped and raised on an elongated axis. Anatomical Features of Ginger in Comparison with Related Taxa. The cells of this zone have the following features: a. cytoplasm deeply stained with pyronin-methyl green and hematoxylin. A violet zone at Rf ~0.53 corresponding to 6-shogaol is present. These scale leaves fall off or may be lost, so that in mature rhizomes only the scars remain. 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 bases of these tillers become enlarged and develop into the primary fingers. Rhizome enlargement in ginger is by the activity of three meristematic zones. [...] The recent root is from one to four inches long, somewhat flattened on its upper and under surface, knotty, obtusely and irregularly branched or lobed, externally of a light ash color with circular rugae, internally yellowish-white and fleshy. These bundles have only one to three vessels and a small phloem. Ginger (Zingiber officinale) is a herbaceous perennial plant of the family Zingiberaceae which used as a spice, food, flavouring agent, and medicine. Perennial plants having thick branching aromatic rhizomes and leafy reedlike stems. Outer corpus cells are vertically elongated. Species differences were also noticed in fiber length, fiber width, and fiber wall thickness. They are spherical and densely stainable. The rhizomes are laterally compressed with a length of around 2.75 to 6 inches and 1 to 1.5 cm width. 2016, 14 (1): 01-09 Phadungcharoen et al. Ginger contains 5 to 8% resinous substances, the chief constituent of which is gingerol. Cytohistological zonation based on staining affinity is not observed at any stage. The perennial rhizome of the ginger plant is a specialized segmented stem structure that grows horizontally just under the soil surface. 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. A comprehensive survey on the anatomy of the plants belonging to Zingiberaceae was that of Solereder and Meyer (1930), in their classical work Systematische Anatomie der Monocotyledonen (Systematic Anatomy of the Monocotyledons). 1. This is darker and smaller than Cochin ginger. There are four stages involved in its development: initiation, differentiation, secretion, and quiescence. (Source: Shah and Raju, 1975a.). The root apical organization in ginger together with many other zingiberaceous taxa was first reported by Pillai et al. The buds on the secondary fingers in turn can develop into tertiary tillers and tertiary fingers. Such stages are noticed about 3,250 ^m from the shoot tip (Ravindran et al., 1998; Remashree et al., 1999). During development, a procambial cell elongates and becomes thick walled with cytoplasm and a prominent nucleus; this is the sieve tube mother cell. The outermost three to five rows of cortical cells are not rich in oil contents. The width of helical tracheids is less than that of scalariform tracheids. D. A main axis with four primary branches and their subsequent branches developing in the same plane. Uses; Benefits; Cautions; Interactions; Other names; References; Uses. Optional: individually dissolve 0.5 mg each of 8-gingerol and 10-gingerol in 1 mL of methanol. Anticlinal and periclinal divisions of these cells result in. Source: Köhler, Medizinal-Pflanzen in naturgetreuen Abbildungen und kurzerläuterndemTexte (1887)[6], Ginger rhizomes (Zingiber officinale) Secondary finger (second-order branch). After planting, many roots having indefinite growth grow out of the base of the sprouts. The leaves are lanceolate, acute, smooth, five or six inches long by about an inch in breadth, and stand alternately on the sheaths of the stem. The transverse wall of the sieve tube changes to simple sieve plates with many pores and with very little callose deposition. The secondary wall thickening in the tracheids of ginger is of two types, scalariform and helical. Cyloplasmic vacuolation initiates in the oil cells at a distance of about 420 ^m from the shoot apex. This is the first formed rhizome knob and is often called the mother rhizome. Figure 6.2 The rhizome of ginger. leaf consists of a leaf sheath, a ligule, and an elliptical—lanceolate blade. 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. The internodal length of the rhizome branches ranges 0.1 to 1.5 cm, and varies even in a single branch. 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. NRCRI (2005) confirmed that ginger grows well in the rainforest region A cork cambium is not evident. More recently, Ravindran and colleagues investigated the developmental anatomy of rhizomes, oil cells, and associated aspects (Remashree et al., 1997; 1998, 1999; Ravindran, 1998). is one of the widely cultivated and consumed spices worldwide. It undergoes a longitudinal unequal division, and the resulting smaller cell gives rise to the companion cell. In the ginger rhizome, four to eight companion cells per sieve tube element are arranged in vertical lines with transverse end walls. The vascular bundles are collateral, closed, and scattered in the ground parenchyma. Pungent, spicy ginger root is one of traditional root herb of culinary and medicinal importance. The cells in this region are arranged in vertical superimposed files. The meristematic activity of the PTM is responsible for the initial increase in the width of the cortex. Pungent, spicy ginger root is one of traditional root herb of culinary and medicinal importance. It belongs to the family Zingberaceae cultivated all over tropical and subtropical countries. The pieces are rounder and thinner, and afford when pulverized a beautiful yellowish-white powder. [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. This zone includes cells belonging to all the structural histogens of the root body (i.e., not structurally delimitable). No need to register, buy now! The large cell is the sieve cell. Table 2.1 Comparative anatomy of four species of Zingiber, Cortex (outer cylinder) Endodermis Casparian strips Cambium Central cylinder, Nature of vascular bundles Vascular bundles distribution, Less in the outer cylinder than in the inner zone, More toward inner cortex and scattered in the central zone, Single layered Periderm with lenticel Not wide, Present Present Not found Wider than the outer zone, Less in the outer zone than in the inner zone, Present Present Not found Comparatively less wider than the outer zone Less in the outer zone than in the inner zone, Vessels few with scalariform/reticulate thickening, More bundles in the middle cortex and number of bundles is very less compared to other 3 species, Present Present Not found Not wider than the outer zone, More in the outer cylinder than the other 3 species but lesser than the inner zone Collateral closed, Bundles are arranged in two rows in the middle cortex and only a few bundles in the inner cortex and the bundles are uniformly distributed in the central zone. In longisection the quiescent center resembles an inverted cup. G. Cytoplasmic condensation. Ginger composes novel phytochemical compounds and holds a special place, even today, in many traditional Indian and Chinese medicines for its disease preventing and health promoting properties. The root cap is not differentiated into columella and a peripheral zone, and hence there are no separate initials for these regions. Three propagule sizes were tested (20, 30 and 40 g) and seven nitrogen levels (0, 40, … What Can You Take To Boost Testosterone Levels, Natural Erectile Dysfunction Treatment System, The ginger plant is a herbaceous perennial grown as an annual crop. Ginger is readily available as a powdered spice, fresh in produce departments and in pill form in the vitamin aisle. An atmospheric pressure ion-source chamber enables us to analyze fresh samples with minimal loss of intrinsic water or volatile compounds. ginger (..S,M. 3. Infected rhizome of ginger showing water soaked lesion were collected from farmers’ field of Ri-Bhoi district in Meghalaya. 1. The early studies on the anatomy of ginger were carried out mainly by the pharmacog-nosists, and they concentrated on the officinal part, the rhizome, either dry or fresh (Futterer, 1896). The main axis developing from the apical bud, which is the first developing branch, has 7 to 15 nodes, which later. 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. During subsequent development of the rhizome apex the cells derived from the inner axial zone elongate and contribute to the pith. A mature rhizome may consist of 6 to 26 axillary branches with foliage leaves or only with sheath leaves and they show negative geotropic response (Shah and Raju, 1975a). It also contains 50% starch, 2 to 3 % proteins and a small amount of sugar. Source: Encyclopedia of Life http://eol.org/data_objects/24891510[9], Ginger Flower (Zingiber officinale) The quiescent center: This zone is found at the tip of the root body, characterized by its cells having (a) cytoplasm highly stained with pyronin-methyl green and hematoxylin, (b) smaller nuclei and nucleoli, (c) cell divisions less frequent, and (d) vacuolation noticeable in most. The distal axial order (cr) includes the central group of corpus cells dividing periclinally and anticlinally and the overlying cells of the tunica (Figure 2.8). Standardized common name (English): ginger No green fluorescent zone is seen at Rf ~ 0.51 (Sharp-leaf galangal fruit). This cell continues to divide, forming four to eight cells. In general, xylem elements in Zingiber consist mainly of tracheids and rarely of vessels. These ducts anastomose and appear branched in longitudinal section. The newly harvested ginger rhizome is yellow; it is called popularly "tender ginger" or "fresh ginger." Scitamineoe), a reed-like plant producing leafy stems a metre high, springing from branching rhizomes. These grains are large, simple, and ovoid, in length varying from 15 to 65 ^m. Procambial differentiation: The peripheral or flank meristem divides periclinally and produces parenchymal cells. In the shoot apex in all stages, a single layer of tunica occurs, showing only anticlinal divisions. 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. These cells are distinct in the dormant or early active rhizome apex and constitute latitudinal growth meristem. The stem has nodes with scale leaves and internodes. is one of the major disease of the ginger (.Zingiber officinalis Rose.) Concurrent separation of the cells leads to the formation of an intercellular space bordered by parenchymal cells. These fibers are very long, but less than 1 mm, have a diameter from 10 to 40 ^m, and are not straight, but undulate in character. Sieve tube: Phloem cells originate from a group of actively dividing procambial cells of PTM. The Jamaica or white ginger is white or yellowish-white on the outside. (1961), Aiyer and Kolammal (1966), and Shah and Raju (1975b). Many plants use these structures for asexual reproduction. Irrespective of the number of primary branches, the subsequent branches lie in the same plane, although alteration of this scheme is seen sometimes. Some cells of pr1 and pr2 (see Figure 2.7) showed dense stainability for C-RNA (cytoplasmic RNA). Introduction Ginger (Zingiber officinale Rosc.) The cells outer and inner to the cambial layer become filled with starch grains. The actively dividing and deeply staining central cylinder shows vascular connections with the rhizome vasculature. B. O. Desalu 1. Rhizomes of ginger are valuable all over the world not only as a spice but also as herbal medicine. The newly harvested ginger rhizome is yellow; it is called popularly "tender ginger" or "fresh ginger." is a creeping perennial on a thick tuberous rhizome, which spreads under ground. In transections passing near the tip of the plerome dome, the initials can be distinguished as a compact mass of isodiametric cells surrounded by radiating rows of periblematic cells. Figure 2.7 Ontogeny of oil cell in ginger: lysigenous development. In the rhizome, oil cell initials are present in the meristematic region. At the early stage of development, the slime body is present in the sieve tube, which appears to be amorphous but homogeneous. Introduction. Mother rhizome. The initiation of oil cells and formation of ducts occurs in the apical parts of shoots and roots and starts much before the initiation of vascular elements. 1. pylori Inhibition and Anti-Oxidative Mechanism. As a ginger plant grows further, several fleshy roots of indefinite growth are produced from the lower nodes of the mother ginger and primary fingers. After storage, the residual … As a rule there is no secondary growth in monocots. Between 10-gingerol and 6-shogaol other weak zones are visible. From shop PJHerbal. 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 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. The transection of a fresh, unpeeled rhizome is almost circular or oval, about 2 cm in diameter, with the outline almost regular. A violet zone at Rf ~ 0.80 may be present. The length of a sieve tube element varies from 57.5 to 103.8 fxm, the average being 76.8 fxm. Rhizome definition, a rootlike subterranean stem, commonly horizontal in position, that usually produces roots below and sends up shoots progressively from the upper surface.
