Study Notes
Artificial Hybridization
- In artificial hybridization, pollination is facilitated by dusting mature pollen grains collected from anthers of the male parent onto the stigma of the female parent.
- This process is followed by rebagging the flowers to allow fruitful development.
- Emasculation is not required if the female parent produces unisexual flowers.
Pollination Process
- Female flower buds are bagged before they open to prevent unwanted pollination.
- When the stigma becomes receptive, pollination is carried out using the desired pollen.
- The flower is rebagged after pollination to ensure successful fertilization.
This quiz covers the process of controlled pollination in plants, including emasculation, bagging, and pollination techniques to ensure desired pollen is used.
