Dhinesh Babu be solitary in clusters (Nath and Randhawa 1959b). Thus, a careful study of floral biology of a plant is important for discerning the mode of pollination (self or cross), types of a Modified from (Wendel & Grover 2015) The phylogenetic tree at the bottom represents the eight diploid groups and contains information about the size of the genome in million bases and number of species in each group. The field is broad and interdisciplinary and involves research requiring expertise from multiple disciplines that can include botany, ethology, biochemistry, entomology and a range of analytical techniques. 2. 5. With respect to floral biology, P. angulata is a monoclinic plant with complete hermaphrodite flowers, containing five petals (pentamer), dichlamydeous, with green cup and yellow corolla. Stem: Herbaceous above and woody below, erect, branched, cylindrical, slightly hairy. Floral Diagram: It sometimes becomes very lucid if the ground plan of a flower be represented in the form of a floral diagram, in a floral diagram the position of the inflorescence axis or stem is shown by a dot or a small circle while the sepals, petals and stamens are put in concentric circles (or spirals when the floral phyllotaxy is spiral), the gynoecium being put at the centre.

Hundred. Petals are yellow in color, valvate, unguiculate (clawed) and cruciform (cross like). It is a reproductive unit in angiosperms. SUMMARY : Flowering plants exhibit enormous variation in shape, size, structure, mode of nutrition, life span, habit and habitat. GENERAL DESCRIPTION Okra Abelmoschus esculentus L. (Moench), is an economically important vegetable crop grown in tropical and sub-tropical parts of the world. Observations on floral biology of mustard crop were recorded. Shortly after, in 1769, Cranz changed this species to Raphanus junceus.Cosson and Czernajew placed it in the genus Brassica ninety years later in 1859. The number of flushes and their importance are determined by cultivar characteristics, crop load and climate. short-styled flowers do not set any fruits. There are five sepals with deep lanceolate teeth (Fig. Flower consists of calyx: sepals 5, united, persistent; corolla: petals 5, united, usually cup shaped; Androecium : stamens 5, alternate with corolla; Gynoecium: carpels are united, ovary superior. ADVERTISEMENTS: Calyx: Sepals 4 arranged in two whorls of two each, polysepalous (2 antero-posterior and 2 lateral), 2 lateral sepals may be saccate, imbricate aestivation, inferior. 3.2 Floral biology Brinjal flowers are large, violet coloured and solitary or in clusters of two or more. predetermined at the time of shoot initiation (Mustard and Lynch, 1946; Núñez-Eliséa and Davenport, 1992; Davenport et al., 2006a). Nitro Pro 8 (8. 21/02/13 6. Flower is a specialized condensed shoot of an angiospermic plant in which the shoot apical meristem gets transformed into floral meristem for carrying out sexual reproduction through progressive specialisation of leaves into floral appendages. Calyx The calyx is dorsally gibbous at the base. The rosettes continue to grow in the win-ter during snow-free periods when temperatures are above freezing. Arabidopsis is not of major agronomic significance, but it offers important advantages for basic research in genetics and molecular biology. Flower biology and pollination in mustard 36 freshly formed buds were tagged on these plants at the time of bud initiation to record the day of opening and sequence of opening on the inflorescence. Corolla is polypetalous (with 4 petals). Widely cultivated in India, Pakistan, Bangladesh, Sri lanka, Philippines Thiwan In India cultivated throughout the plains & up to elevation of 1820m Cultivated in all three seasons- … BIOLOGY OF ABLEMOSCHUS ESCULENTUS L.
