Non Biodegradable Pollutant

The steps in artificial hybridisation are:
Emasculation: Removal of stamens from the bisexual flowers of the female parent to prevent self-pollination.
Bagging: Covering the emasculated flower with a bag to prevent contamination from unwanted pollen.
Pollination: Dusting pollen from the male parent onto the stigma of the female parent.
Re-bagging: Re-covering the flower to ensure fertilization occurs without external interference.
