In transections, the cells of the columella form a compact mass of polygonal cells in the center with the cells of the peripheral region arranged in radiating rows around it. However, intercropping ginger with 24074 maize plants per hectare produced ginger rhizome yield of 10.84 tonnes ha-1 which was significantly (P ≤ 0.05) comparable with highest rhizomes yields of 14.08 tonne sha-1 obtained in sole ginger crop (P≤ 0.05). 4. No fibers are present enclosing these small bundles. Lawrence BM. Young scale leaves have pointed tips that help in penetration of soil. The axillary buds thus originate as a cellular patch in the adaxial side of a leaf or scale leaf of the node. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). 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. 2. A distinct continuous layer of epidermis is generally present, consisting of a single row of rectangular cells; in some cases, it may be ruptured. The experiments were conducted at the Teaching and Research Farm, Ladoke Akintola University of Technology, Ogbomoso, Nigeria in 2010 and 2011 to determine the effect of propagule size and nitrogen levels on the growth and rhizome yield of ginger. The plant has narrow; lanceolate to linear-lanceolate, The root tip can be distinguished into two zones on cytophysiological grounds: 1. (1998), and Ravindran et al. During subsequent development of the rhizome apex the cells derived from the inner axial zone elongate and contribute to the pith. Macroscopic Characteristics The main rhizome (round turmeric) is ovate or pear-shaped, up to 4 cm. 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.

Source: Encyclopedia of Life http://eol.org/data_objects/24891510[9], Ginger Flower (Zingiber officinale) The meristematic activity of the PTM is responsible for the initial increase in the width of the cortex. The interior parenchyma is whitish, the cells being filled with starch. 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] 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. The aerial shoots have many narrow leaves borne on very short petioles and with sheaths that are long and narrow, and the overlapping sheaths produce the aerial shoot. The concentrated extract was analysed by HPLC for [6]-gingerol, the major pungent principle of the oleoresin. Roots always develop just below the nodal region. Maton. 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. Later the slime body disintegrates. After planting, many roots having indefinite growth grow out of the base of the sprouts. Family: Zingiberaceae. 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. 1. The branches (1-3cm length) arising from the rhizome are oblique to it and end in undeveloped buds or depressed scars. These stages occur between 1500 and 3000 ^m from the apex. The development of leaves and scale leaves that encircle the shoot apex in ginger rhizomes is in a clockwise direction. In the ginger rhizome, four to eight companion cells per sieve tube element are arranged in vertical lines with transverse end walls. The width of helical tracheids is less than that of scalariform tracheids. B. Division of mother cell. Use: Dip (time 0, speed 5), heat at 100C for 3 min. It has been used for thousands of years as a medicine for a multitude of ailments. Geographical source: ADVERTISEMENTS: Jamaica, South India (Cochin), Africa, Japan . Primary finger (first-order branch). Test for adulteration: Under UV 366 nm no green or blue fluorescent zones are seen at Rf ~ 0.22 and 0.34 (Lesser galangal rhizome). Habit. Further separation of the bordering cells along the radial wall leads to widening of the duct lumen. PubMed: ... PubMed:Gastroprotective Effect of Ginger Rhizome (Zingiber officinale) Extract: Role of Gallic Acid and Cinnamic Acid in H(+), K(+) -ATPase/H. The schizogenous type of secretory duct originates in the intercalary meristem of the developing regions. 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. No need to register, buy now! Ginger has distinct anatomical features compared to other species, such as the absence of periderm, short-lived functional cambium, the presence of xylem vessels with scalariform thickening, helical and scalar-iform type of xylem tracheids, scalariform perforation plate, outer bundles with a col-lenchymatous bundle sheath, and high frequency of oil cells. The macroscopic and microscopic characters, physical constant values, extractive values, ash values and the behaviour of powder drug on treatment with different chemical regents, microchemical and histochemical analyses were conducted to characterize some pharmacognostical parameters of Curcuma amada linn. The distance between the tip of the root body and the nearest mature phloem element, which carries the metabolic products required by the active cells, was reported to be 480 to 490 ^m. Adequate tests on reproductive toxicity , It is found in water grasses (typha). No green fluorescent zone is seen at Rf ~ 0.51 (Sharp-leaf galangal fruit). 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. The nitrogen source was from Tithonia compost (TC). In the present study, various concentrations of extract prepared from Z. zerumbet were screened for its activity against Pythium myriotylum. In general, xylem elements in Zingiber consist mainly of tracheids and rarely of vessels. NRCRI (2005) confirmed that ginger grows well in the rainforest region Silica gel 60, F254, Mobile Phase Ethyl acetate, formic acid, water 88:6:6 (v/v/v). Some studies were carried out by Pillai et al. This page was last modified on 26 May 2015, at 18:58. The Jamaica or white ginger is white or yellowish-white on the outside. 61. The axillary buds show vascularization by the activity of the procambial strands of the mother rhizome and procambial cells originated from the differentiation of parenchymal cells. The protoderm—periblem complex is located outside the plerome and is composed of a single tier of cells. The shoot apex dome at stage four is 140 to 160 ^m high and 90 to 116 ^m wide. becomes an aerial shoot. Ginger is readily available as a powdered spice, fresh in produce departments and in pill form in the vitamin aisle. These variations were presented in a comparative study of ginger and three other species (Ravindran et al., 1998). Quiescence and secretory stages are visible from the third month onward after planting. Source: United States Dispensatory (1918) [3]. After storage, the residual … These vessels have a diameter varying from 21 to 66 ^m. 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. is one of the widely cultivated and consumed spices worldwide. Rhizomes of ginger are valuable all over the world not only as a spice but also as herbal medicine. The above characteristics show their state of rest and are called the quiescent center. The internodal length is more in secondary, tertiary, and quaternary branches, and in the aerial stem it ranges from 3 to 7 cm. Above its region of insertion, the sheath encircles the internode; and from the side opposite to its origin up to the ligule, the sheath is open longitudinally. Near the dome, cells take less stain because of their quiescent nature. Many plants use these structures for asexual reproduction. Find the perfect fresh ginger rhizome stock photo. This ginger is more pungent but lacks the aroma of Jamaica ginger. 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. 1. It is the oldest rhizome widely domesticated as a spice. In a longisection, the shoot apex is dome shaped with a single tunica layer, below which the central mother cell zone is present. (Source: Shah and Raju, 1975.). ab, axillary bud; as, aerial shoot; cr, central zone; lba, leaf base; lp1, lp2, leaf primordium; pr1, pr2, peripheral zone; rr, inner aerial zone; sr, seed rhizome; sz, shell zone. Similar tracheids are present in Z. macrostachyum, whereas in Z. zerumbet and Z. roseum, only scalariform thickening occurs (Ravindran et al., 1998). Later Tomlinson (1956) supplemented the information and filled in the gaps. Standardized common name (English): ginger   The inner limit of the cortex is marked by a single-layered endodermis composed of thin-walled rectangular cells, much smaller than the cortical cells, with their radial walls slightly thickened and free from starch grains. This is darker and smaller than Cochin ginger. The cells in this region are arranged in vertical superimposed files. Such stages are noticed about 3,250 ^m from the shoot tip (Ravindran et al., 1998; Remashree et al., 1999). 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. In the enclosing sheath of fibers the number of cells varies very much. These fibrous roots are thin, have root hairs, and their function is mainly absorption of water and nutrients. The bases of these tillers become enlarged and develop into the primary fingers. This is in direct connection with the vascular ring situated beneath the endo-dermoidal layer. It is imperfectly washed and coated. The flank meristem is situated on either side of the central mother zone. It belongs to the family Zingberaceae cultivated all over tropical and subtropical countries. These scale leaves fall off or may be lost, so that in mature rhizomes only the scars remain. The perennial rhizome of the ginger plant is a specialized segmented stem structure that grows horizontally just under the soil surface. Ayurvedic name(s): ardraka (fresh rhizome); shunthi (dried rhizome)   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). An empty cell or cells with distorted cytoplasm appear along the duct lumen. What Is the Keto Diet and Should You Try It? 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 leaf is initiated from the outer tunica layer and from the flank meristem. (a) Germinating bud appears from the eye of the stem tuber. The procambial cells and the ground meristem cells divide and parenchyma as well as vascular tissues add thickness to the newly enhanced axillary bud. Ground sun-dried Jamaican ginger rhizome was treated with supercritical CO2 (density 0.415-0.775 g cm-3) over the pressure range 128-197 bar (1850-2850 psi) and temperature range of 50-65°C. 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. The outer surface of the rhizome was grey but inner yellow colour with bitter odour and fragrant aromatic odour (Figure.1). A violet zone at Rf ~ 0.80 may be present. This is the first formed rhizome knob and is often called the mother rhizome. [...] 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. 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. 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°. The roots of ginger are of two types, fibrous and fleshy. This process that takes place in adjacent cells leads to the formation of a duct. Zingiber officinale Roscoe   Zingiberaceae   Pillai et al. Ginger consists of the rhizomes of Zingiber officinale, Roscose and dried in the sun. Cells of the pr2 zone show dense staining. The rhizomes are carefully dug up with hard picks, washed and dried. The vascular bundles are collateral, closed, and scattered in the ground parenchyma. Beneath the epidermis is a brownish, resinous, almost homy cortical portion. Source: PlantaPhile[7], Ginger Aerial Parts and Flower Ginger has been used throughout history as an aid for many for its gastrointestinal disturbances and to relieve inflamed joints (Katzer, 2007). 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. 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). insects, animal faeces, mold, fungi, etc.) In the base of the rhizome apices, cells derived from the inner axial zone elongate tangen-tially and contribute to the widening of the axis. body weight) for 8 weeks as well. Information about the open-access article 'PHYTOPHARMACEUTICAL POTENTIAL AND MICROSCOPIC ANALYSIS OF RHIZOMES OF CURCUMA LONGA AND ZINGIBER OFFICINALE (ZINGIBERACEAE)' in DOAJ. The isodiametric cells at the very center of the plerome divide like a rib meristem to give rise to the pith. The lysigenous type of duct formation is more frequent in the meristematic region, but occurs in mature parts too. As this tiller grows, its base enlarges into a rhizome. PubMed:Protective effect of ginger volatile oil against acetic acid-induced colitis in rats: a light microscopic evaluation. Xylem vessels occur in ginger and not in other species. B—D. Present, Inflorescence and fruit - Pineapple Fruit, Physical and Emotional Benefits Of Aromatherapy, Turmeric Health Benefits and Culinary Uses. Normally, these roots originate from the lateral or opposite side of the axillary bud and scale leaf. 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. Pith cells differentiate in the inner axial zone (rr). Quiescence: In the mature rhizome the ground parenchyma does not undergo further division and differentiation into the duct. The shoot apex is 91 to 112 ^m in width and 134 to 167 ^m in height. Plerome has at its tip a group of more or less isodiametric cells. Later these cells elongate, vacuolation increases, and they develop gradually into sieve tubes. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. It also contains 50% starch, 2 to 3 % proteins and a small amount of sugar. 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. On the sides of the plerome dome is the uniseriate pericycle. The terminal part of the rhizome or a … In the shoot apex in all stages, a single layer of tunica occurs, showing only anticlinal divisions. The rhizomes are laterally compressed with a length of around 2.75 to 6 inches and 1 to 1.5 cm width. It gradually merges with the zone outside, the meristematic zone. The following discussion is adapted from Pillai et al. B. O. Desalu 1. In the present study, the effect of ginger (rhizome of Zingiber officinale Roscoe) volatile oil on a rat model of colitis was evaluated. Subsequently the surrounding cells also enlarge in size, showing cytoplasmic and nuclear disconfigurations (see Figure 2.7E, F). It has cytoplasm and nucleus in early stages, which degenerate during its development into the sieve tube. 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. Macroscopical Character: i. Colour- Yellow to yellowish brown externally, yellow to yellow orange internally. Results: In the second week results revealed EMF exposure identification using molecular character-ization technique. The rhizome of ginger is buff colored with longitudinal striations or is fibrous with no cork. one bud may develop simultaneously. As the enlarging root primordia emerge through the cortex, the cortical cells are crushed and torn apart. Optional: individually dissolve 0.5 mg each of 8-gingerol and 10-gingerol in 1 mL of methanol. Raju and Shah (1977) also reported a similar observation in ginger and turmeric. The cells of this zone have the following features: a. cytoplasm deeply stained with pyronin-methyl green and hematoxylin. The pieces are rounder and thinner, and afford when pulverized a beautiful yellowish-white powder. Rhizome. The rhizome is considered the most useful part of the plant. 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. b. divides more frequently c. have larger nuclei and nucleoli d. vacuolation is absent or not prominent. Endodermis differentiates from the innermost periblem cells. Boesenbergia, Kaempferia, Globba and other low herbs the rhizome is mostly short. Ginger is the underground rhizome of the ginger plant with a firm, striated texture. Rhizome definition, a rootlike subterranean stem, commonly horizontal in position, that usually produces roots below and sends up shoots progressively from the upper surface. The leaf sheath is about 15 to 18 cm and lamina about 12 to 15 cm long. 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. In transection, an endodermoidal layer is also visible during the development (Remashree et al., 1998; Ravindran et al., 1998). A few cells toward the flank showed increased concentrations of DNA as evidenced by dense staining. Between 10-gingerol and 6-shogaol other weak zones are visible. The buds on these primaries develop in turn into secondary tillers and their bases into secondary fingers. A pair of ligules is formed at the junction of leaves and sheath. Subsequent development of the secondary, tertiary, and quaternary branches are on the abaxial side of the respective branches. These are the procambial initials and each such group contains 15 to 20 cells. More recently, Ravindran and colleagues investigated the developmental anatomy of rhizomes, oil cells, and associated aspects (Remashree et al., 1997; 1998, 1999; Ravindran, 1998). They are spherical and densely stainable. Pungent, spicy ginger root is one of traditional root herb of culinary and medicinal importance. In ginger, the roots emerge Ginger translation in English-Kinyarwanda dictionary. The median longisection of this group of cells is in the shape of a cup with the rim forward. This zone includes cells belonging to all the structural histogens of the root body (i.e., not structurally delimitable). Zingiber officinale Rosc. Outer corpus cells are vertically elongated.
