Question

What will happen if pollen grain of rose gets deposited on the stigma of lily flower? Will pollen germination takes place? Why?

Accepted Answer

When pollen grain of rose gets deposited on the stigma of lily flower, germination of pollen gain will not occur. In case of cross-pollination, pollen grain will land on the stigma of the same flower of other plants. Though both the plants are from the same species, each belongs to a different variety. So they are genetically different. Another point we have to discuss here that pollen-pistil interaction.

Pollen pistil interaction:- It is the group of events that occur from the time of pollen deposition over stigma to the time of pollen tube entry into the ovule. The pistil can recognize the compatibility of pollen with the help of special proteins is a safety measure to prevent illegitimate crossing.
