The seed is the outcome of sexual reproduction in flowering plants. It represents the beginning of a new generation. A seed is defined as a fertilised mature ovule that possesses an embryonic plant, stored food material and a protective coa..

In the life of most flowering plants, 3 distinct phases are seen. i) Seed germination and vegetative growth phase ii) Reproductive phase iii) Senescence and dea..

ABA is also used in inducing flowering in short day plants, rooting of stem cuttings and for inducing dormancy in buds and seeds..

This division is made up of plants that bear flowers and seeds and make up the majority of the larger plants. The body is differentiated into true stem, leaves and roots. Propagation of the plant takes place with the help of seeds. Seeds are formed as a resu..

In flowering plants, flowers have taken the place of conventional sex organs, and the ovules which later on develop into seeds are enclosed within an ovary. The sexual reproduction in angiosperms involves the fusion of two gametes, the male and the female. The ma..

In plants such as wheat, rice, gram and mustard the plants die after seed production. This is also observed in monocarpic plants which live for several years but flower only once in their life time as in sago palm and bambo..

Gregor Mendel was the first to carry out scientific studies on transmission of characteristics from the parent to the offspring. He selected garden peas as they showed many contrasting traits that were easy to track through the generations. Moreover, these plants are naturally self-pollinated. This..

Seed soil and water borne diseases mostly attack roots and plant stem. Air borne diseases attack all aerial parts of the plant i.e. leaf, flower and fruit. Seed and soil borne diseases can be controlled by treating the seed and soil. Air borne diseases ..

Mendel could not note linkage because of the seven characters be studied in garden pea, most of them are located in different (non-homologous) chromosomes seed colour and flower colour are in the same chromosome i.e, they are linked. However, they lie so far apart that they get ..
