POLLEN GERMINATION CAPACITY AND MAINTENANCE OF POLLEN IN PRAECITRULLUS FISTULOSUS (STOCKS) PANGOLA (CUCURBITACEAE)
ANJUM PERVEEN AND SHAUKAT ALI
Abstract: Pollen germination of Praecitrullus fistulosus L., of the family Cucurtbitaceae was examined in fresh and stored pollen upto 48 weeks at different temperatures i.e., -30°C refrigerator (+4°C), freezer (-20° C, -30°C) and freeze drier (-60°C). Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4°C and fresh. Pollen stored at -30°C (freezer) showed the highest germination percentage.
