Hints & Solutions

(d) Anthesis is the period during which a flower is fully open and functional. It may also refer to the onset of that period. For emasculation the knowledge of flower structure, mechanism of pollination, fertilisation and physiology of flowering is essential for this. In emasculation technique the stamens are removed before anthesis to obtain female parent and pollen from the desired male parent is transferred on to its stigma.
