Abstract:

The pollen grains of raspberry exhibited the average size (length x width) of 177.73 x 124.43µ in glycerol conditions, followed by (173.29 x 173.29 µ) in water suspension. The viability of fresh pollen grains ranged from 32.50 % to 97.70 % in hermaphrodite or bisexual flowers. 25 % sucrose solution + 0.4 % boric acid solution showed the highest pollen germination of 36.66% with the maximum pollen tube length (284.37µ) after 48 hours interval. After 3 days storage, the pollen grains were quite normal and showed 46.66 % germination. The longevity of pollen grains stored under room conditions indicated that on the third day of storage, the pollen grains were quite normal and showed 97.70 % germination. But after that the longevity of pollen decreased rapidly and after 9 days of storage, the viability dropped to nill. The stigmas were 86.66% receptive on the day of anthesis. Bag self-pollination resulted in the highest fruit set (96.66 %) as compared to hand self-pollination and open pollination.
