What is the purpose of bagging in artificial hybridization?
To protect the flower from pests and diseases.
To collect the pollen for controlled pollination.
To facilitate self-pollination in plants.
To ensure that only desired pollen reaches the flower.
The purpose of bagging in artificial hybridization is to ensure that only desired pollen reaches the emasculated flower and prevents unwanted cross-pollination. By isolating the emasculated flower with a bag or a mesh enclosure, breeders can control the pollination process and ensure that the desired pollen, typically from a different plant, is used for fertilization. This helps to create new plant varieties with desired traits and genetic characteristics. Bagging also helps to prevent contamination from foreign pollen and ensures the purity of the resulting hybrid.
Option 4 is the correct answer.
