Enlist the steps of controlled cross-pollination. Would emasculation be needed in a cucurbit plant? Give reasons for your answer.

(N/A) Steps of controlled cross-pollination:
$1$. Selection of parents
$2$. Emasculation (removal of anthers from the flower bud of the female parent)
$3$. Bagging (covering the emasculated flower with a suitable bag)
$4$. Collection of pollen from the male parent
$5$. Dusting the pollen on the stigma of the female parent
$6$. Re-bagging (re-covering the pollinated flower)
Emasculation is not needed in a cucurbit plant because it produces unisexual flowers. In unisexual flowers,the male and female reproductive organs are present in separate flowers. Therefore,the risk of self-pollination is naturally absent,and manual removal of anthers is unnecessary.
