Answer:
Pollen banks are playing a very important role in promoting plant breeding programme the world over. Pollens are preserved in the pollen banks by storing them in the viable condition in a low temperature of -196 degree Celsius with the help of liquid nitrogen this is known as cryopreservation.
Answer:
pollen banks are used to store pollens for a very long period of time in viable conditions. Pollens are preserved in a bank using cryopreservation
i.e., they are stored in a viable condition in low-temperature conditions (-196 degree celcius ) using liquid nitrogen.
The important applications of pollen banks for our farmers are the following :
i. To preserve the agricultural biodivercity in the form of preservation of valuable genetic resources.
ii. These pollens can be used in various crop hyberdization breeding programmes , biochemical and physiological studies such as the study of allergens etc.
