Question

Use of sucrose in Pollen germination

Answer 1

In nature,pollen grain germinate on the compatible stigmas of the carpel.Stigma secretes a sugary liquid which stimulates germination.Pollen grains can also be induced to germinate in a synthetic medium.Sucrose is used as a pollination solution(Medium).Sucrose induces the pollen germination & tube growth in vitro.Also the externally supplied sucrose maintains the osmotic pressure & acts as a substrate for pollen metabolism.
