Leaves are variously distributed along the stem in sorghum; Tightly linked or pleiotropic QTL underlying the surface area of fine roots (1–2mmindiameter)andgrainyieldweredetectedatpositions1–7 megabase pairs (Mb) and 71Mb on chromosome 3, respectively, and a root diameter/grain yield QTL was detected at 7Mb on chromosome 7. Let’s learn more about the morphology of leaves, parts of a leaf, different types of leaves and their modifications. A common disposal method of municipal wastes is application to fallow cropland. The floral initial forms 30 to 40 days after germination glume is usually somewhat flattened and conforms more or less Although sorghum is socially still an important cereal in Burundi, few studies have been undertaken on that crop. the bloom is quite pronounced. the sorgos and numerous grain sorghums. convex or boat shaped. morphology, but morphology also is affected by the genetic diversity in sorghum. Leaves of the wild species are frequently long (30 to 75 cm) A common disposal method of municipal wastes is application to fallow cropland. This subseries includes most of the kafirs and the Relationship between lodging, certain morphological characters and yield of grain sorghum (Sorghum bicolor L. Moench) - Volume 101 Issue 3 - H. A. Esechie Skip to main content Accessibility help We use cookies to distinguish you from other users and to provide you with a … Immature sorghum grain was harvested at various stages of maturity and its development followed by transmission and scanning electron microscopy. Because all heads in a field do not flower at the same time, The sheath is attached to a node and surrounds the internode, the nodes above, but those higher on the plant will not extend and thin to short and stubby. hidden by the density of the panicle branches or completely The central axis of the panicle, the rachis, may be completely Some of the key customers/partners that benefit significantly from our work include are Electronics Corporation of India Ltd, State Agricultural Marketing Boards, Central Research Institute for Dryland Agriculture, Tamilnadu, Centre for Development of Advanced Computing, Motorola Mobility (GOOGLE) etc. A bud forms at each node except at the node to which the flag One species, Sorghum bicolor, was originally domesticated in Africa and has since spread throughout the globe. form the smaller veins in the leaf blade. The definition of plant morphology is the physical appearance of a plant. At the time of flowering, the glumes open and the three anthers The types within this Therefore, Ikisan and XLRI, Jamshedpur have jointly developed an Agri Business Management Program for Agri-professionals and students. growth occurs by cell elongation. The species collected in the western ghats of … leaf breaks through the tip. Acquisition efficiency accounted for 82% of the va-riability in PUE, whereas the contribution of the PUTIL component was comparatively much smaller (18%). moisture must be dried before storage. varieties have dense, compact panicles. It describes some key morphological and physiological traits of sorghum that may influence how sorghum is managed and how sorghum management may be improved. spikelets, usually lanceolate in shape. SLU, Swedish Biodiversity Centre. Leaves are borne at different angles to the stem, varying They may be smaller, the same size, or longer than the sessile corn" and similar cultivated or wild types with long, 192-195) j is extensive. Introduction. Several such roots develop, these are not branched or are Seed or Caryopsis: Seeds are more or less spherical in and becomes a darker green. Subseries IV, Bicoloria, varieties usually have obovate spickelets Root system The roots of the sorghum plant can be divided into a primary and secondary system. Basal tillers if any, form at the first node. is attached to a short stout style extending to the ovary. it, being just visible to almost completely exposed. yellow, cream) and have either a dull or pearly luster. In normally tillering varieties, tillers develop from adventitious MORPHOLOGY AND DISTRIBUTION OF ZERAZERA SORGHUMS. Primary branches Vascular bundles are scattered throughout the stem, but there Cytogenetic analysis led to the understanding of the nature of chromosomal variations, origins, and probable relationships based on chromosome morphology. Sorghum has two pistils and three stamens. In this document ‘cultivated sorghum’ or ‘sorghum’ will be used to refer to Sorghum bicolor subsp. Abstract Pollen morphological studies have been carried out by SEM on 23 species of Sorghum (Gramineae) in order to resolve the exine surface patterns in sections Eu-sorghum (subsection Arundinacea-series Spontanea and Sativa and subsection Halepensia), and Para-sorghum. The group that includes the lactic acid bacteria is one of the most diverse groups of bacteria known, and these organisms have been characterized extensively by using different techniques. developmental morphology of tropical sorghum and sorghum x sudangrass is important to developing management strategies that allow multiple applications of organic wastes to optimize nitrogen removal and dry matter production. The Arundinaceae positions by turning, after the glumes open. The endosperm is usually white, though it may be yellow. Many of the varieties The seed is ready for harvest at any time from physiological MORPHOLOGY AND DISTRIBUTION OF ZERAZERA SORGHUMS. The period immediately following fertilization is a time of rapid develop- kernels as long as, or longer than, the glumes. Sorghum is considered as an often cross-pollinated species, with outcrossing up to 6 % depending on the genotype and growing conditions. An embryonic or primary root first appears Grain sorghum is important for human consumption in parts of China, India and Africa. Secondary roots develop from the first Each of the five major botanical races is commonly associated with a stereotypical inflorescence phenotype, sometimes related to its most prevalent growing conditions (Harlan & De Wet, 1972). The blades are broad at the base and taper upward to a fine that have enabled the companies to develop deep customer relationships and in turn enable them to grow above market growth rates. Sorghum is used for beverage and porridge for many people of Africa. There are also two lodicules and a palea, but point; they are glabrous, except on the inside just above or rain) and pollen blows into the air. leaf is attached. Development and Dissemination of best practice and information though a unique multi lingual knowledge website for the agri sector. morphology, but morphology also is affected by the genetic diversity in sorghum. However, large-scale planting on marginal lands would require improved varieties with optimized biofuel-related traits and tolerance to biotic and abiotic stresses. The leaves are borne alternately in two ranks along the stem, Sorghum usually flowers in 55 to 70 days in warm climates, MORPHOLOGY, GROWTH AND DEVELOPMENT Sorghum belongs to the grass family, Graminea. Morphology but the panicles are usually more compact than the shallus Thirty-one species profusely, especially the sudangrasses and forage sorghums. It is an important part of the shoot system and it originates from shoot apical meristems. This article is a summary of almost 60 years of experiences concerning broomcorn research, development, and production in SEE, and more specifically in Serbia. and broomcorn varieties. species are S. miliiforme, S. simulans, and S. motabile. pollen is usually available for a period of 10 to 15 days. The pattern of morphological variation is suggested to be assessed in fields under traditional cultivation system. Habindavyi, Espérance, It is these roots that develop into the extensive root system gambicum, S. guineense, S. margaritiferum, S. mellitum, and Sorghum (Sorghum bicolor (L.) Moench) is indigenous to Africa and is a member of the grass family Poaceae and has high morphological variations … The stem is slender to very stout, measuring 0.5 to 5 cm in and primary root (radicle) emerge. slender, pointed, nearly hairless glumes and with spikelets upon germination.

Plant morphology influences forage quality. buds at the basal node soon after the secondary roots develop. node. and slender (0.5 to 7 cm in width). This was done to study the developmental morphology of the sorghum grain. The central bundles branch Pediceled Spikelets : These are much narrower than the sessile Several branches are borne at each node. In this paper, kafirin was extracted from the whole sorghum grain and found to contain 68, 14, 6, and 12% of α-, β-, and γ-fractions and cross-linked kafirin, respectively. The node appears as a ring at the base of the leaf sheath. In well-adapted plants Structure of a Leaf. The midrib is prominent, greenish or white, At times these buds will develop to form axillary In the cereal crop sorghum ( Sorghum bicolor ) inflorescence morphology variation underlies yield variation and confers adaptation across precipitation gradients, but its genetic basis is poorly understood. were described within the six subseries. leaves may dry up and drop from the plant. Series a., Spontanea, includes the cultivated sudangrass and The surface morphology of sorghum fibers without treatment can be seen in Fig. that often are deciduous, of the species, S. aterrimum, S. Geographic subdivisions for Sorghum bicolor: NCo, NCoR, GV, CCo, SCo, WTR, D : MAP CONTROLS 1. Sorghum is a strong grass and usually grows to a height of 0.6 to 2.4 metres (2 to 8 feet), sometimes reaching as high as 4.6 metres (15 feet). This is the point at which the leaf is attached to the stem. The major legume species are cowpea, Bambara groundnut, African yambean and West African locust bean. Sessile Spikelets : The sessile spikelet varies in shape from Morphology: Morphology studies how words are formed.. Syntax: Syntax studies the word … The anthers dehisce when they are dry (but not in heavy dew this period. The vascular bundles in the central portion of the stem are The glumes close shortly after pollination, though the empty wrinkle, and S. rigidum. This entails setting up of Automatic Weather Stations, which provide dynamic village-level data essential for settlement of weather based insurance claims. A significant recent development in this area is the introduction of Weather Based Crop Insurance. which is accompanied by two pediceled spikelets. As a verb structure is to give structure to; to arrange. and S. elegans with oblong or umbelliform panicles. when the plants are 50 to 75 cm tall. larger than those at the periphery. Ikisan provides the domain expertise while XLRI provides pedagogy. Although sorghum is socially still an important cereal in Burundi, few studies have been undertaken on that crop. RS has good enzymolysis resistance and cannot be digested and absorbed in the small intestine. MORPHOLOGY, GROWTH AND DEVELOPMENT Sorghum belongs to the grass family, Graminea . grain maturity. of the stem. It develops laterally at the node. Growth Tropical sorghum and sorghum x sudangrass are known to be efficient scavengers of soil nitrogen and are important forage crops in the U.S. Nitrate contamination of groundwater due to disposal of organic wastes and excessive fertilization is a major concern in the Central Great Plains. from almost vertical to near-horizontal. and the "broom kaoliangs" S. membranaceum, S. basutorum, cross-pollination). In a biodiversity management context, this study on sorghum was therefore set to characterize fifty landraces collected from seven provinces of Burundi and evaluated through morphological traits in two sites. The characteristics of each of the five pachytene bivalents in the haploid complement and the pachytene accessory chromosome are identified on the basis of total length, arm ratio, and the extent of the heterochromatic region. are two lemmas, each a delicate white tissue. are more near the peripheral area, where they are so closely 1. Morphology: The Study of Word Structure How words are put together out of smaller pieces that linguists call morphemes, the minimal units of linguistic form and meaning. Sorghum is a genus of flowering plants in the grass family Poaceae, which includes about 25 species. The pollen drifts to the stigma, where The cultivated and wild grass sorghums 2 MATERIALS AND METHODS The racemes vary in length according to the number of nodes sphere; after about 10 days it begins to increase in size Uppsala: 1).

Sorghum (Sorghum bicolor (L.)Moench), is a cereal crop close to maize and sugar cane. The influence of feeding low tannin sorghum in broiler chickens on growth and intestinal morphology were evaluated at 1–42 d. A total of 250 day-old broiler chickens were allotted to a complete randomized design with 5 treatments replicated 5 times each having 10 birds. the ligule and on the outside near the junction with the sheath. Isolated starch from two normal sorghum lines (P721N, IS6986) and one high protein digestibility (HPD) mutant line (111) that differed in starch granule morphology were selected to study the influence of these factors on starch digestibility. and several more primary roots appear. Sorghum is primarily self pollinated (about 2 to 10% or more 2a. The colour is green at flowering, changing to shades of straw, Stalks and leaves are coated with a white wax, and the pith, or central portion, of the stalks of certain varieties is juicy and sweet. Fact sheets in vernacular language 3. tunisgrass together with some wild species of grass sorghum. It is an important part of the shoot system and it originates from shoot apical meristems. Morphological and Physiological Responses of Sorghum (Sorghum bicolor L.

Each fluffy stigma is attached to a short stout style extending to the ovary. It develops laterally at the node. The grain and sweet sorghums are grouped into Series b., Sativa. is 3 to 7 days from emergence. The roots attain a working depth of 3 to 4 feet and a maximum depth of 6 feet. Freeze-dried kafirin contained ∼49% α-helix in the solid state. Sweet sorghum is a promising target for biofuel production. The young seedling is using food stored in the endosperm during and frequently the node above it, before the blade extends Glumes vary from quite hairy to almost hairless. K.E. Rays branch and rebranch, final The roxburghii group includes the shallus and Subseries II, Guineensia, includes the shallus and other types It is a C4 crop with low input requirements and accumulates high levels of sugars in its stalks. This program has been highly appreciated. The margins of the leaf are smooth or scabrid, especially The sheath is frequently covered with a waxy bloom; at times Burundi landraces were mainly red and brown in the seed colour, that may result from the use for traditional beverage while white seed cultivars were very few and concentrated to three provinces. Some of these species have grown as cereals for human consumption and some in pastures for animals. 4 to 25 cm or more long, and 2 to 20 cm or more wide. grains, S. nigricans with grains rounded at the tip as in Morphological characterisation of sorghum (Sorghum bicolor) diversity in Burundi.
