Answer the following question.
You are conducting artificial hybridization on papaya and potato. Which one of them would require the step of emasculation and why? However, for both, you will use the process of bagging. Justify giving one reason.

उत्तर
Potato plant bears bisexual flowers. This is the reason that the process of emasculation, that is, removal of stamen will be performed in potato and not in papaya that bears unisexual flowers. However, bagging is performed in both the flowers because the stigma needs to be protected from getting pollinated with undesired pollen.
