Emasculation: If the female parent bears bisexual flowers, removal of anthers from the flowrer’s bud before the anther dehisces using a pair of forceps is necessary. This step is reffered to as emacalculation.
Bagging: Emascalculated flowers of bagged have to be covered with a bag of suitable size, generally made up of butter paper, to prevent contamination of its stigma with unwanted pollen. This process is called bagging.
Importance: When the stigma of bagged flower attains receptivity, mature pollen grains collected from anthers of the male parents are dusted on the stigma and the fruits are allowed to develop. If the female parent produces unisexual flowers, there is no need of emacalculation. The female flower buds are bagged before the flowers open.When the stigma become receptive, pollination is carried out using the desired pollen and the flower rebagged.
