Pollen, the plant constitution most generally utilized by people, is a key constitution in plant replica giving upward push to end result and seeds. furthermore, the biotechnological use of pollen is of significant value for plant breeders because it permits to procure forms with greater usage and yield. within the first half, the successive steps of pollen improvement within the anther from floral induction to pollen germination and fertilization are completely tested; the second one half is dedicated to pollen behaviour in vitro.
