Answer 2

Viability period of pollen grains for several months is observed in Some members of family Solanaceae.

• Fruit set and seed set are the most reliable tests for pollen viability since pollen viability is defined as the ability of pollen to cause fertilization and subsequent development of fruit and seed.
• Following controlled pollinations of stigma compatible with the test pollen samples, the seed set is assessed.
• One month is about how long Rosaceae and Solanaceae pollen grains are viable. Through generative cells, the meiotic division produces male gametes.
• Pollen grains lose vitality in some cereals, such as rice and wheat, within 30 minutes of release, but they retain viability for a month in some Leguminosae, Rosaceae, and Solanaceae species.
