Influence of Pollen viability on Quantity and Quality of Seeds in Bitter Gourd {Momordica charantia L.)

摘要

Studies on pollen grains of Bitter gourd (Momordica charantia L.),which belongs to the family Cucurbitaceae, was carried out in commercial vegetable farm in Kerala, India. Observations were done at different time intervals in the flowering season to understand influence of pollen viability on quantity and quality of seeds. Germination assays showed highest percentage of viable pollen grains in the initial phase of the day and middle phase of the flowering season and lowest in late phase of day and late phase of flowering season.
