Solution

Cross-pollination of a hermaphrodite flower (flower bearing both stamen and pistil) can be achieved by

(1) Emasculation: The anther is removed from one of the flowers.

(2) Bagging: The emasculated flower is covered by a bag so as not to allow contamination of the stigma by unwanted pollen grains. When the stigma of the bagged flower becomes receptive, the pollen grains collected from the other flower are dusted onto the stigma and then the flower is rebagged.
