ANJUM PERVEEN AND SHAUKAT ALI KHAN
Abstract
Pollen germination of Malus pumila L., of the family Rosaceae was examined upto 48 weeks in a refrigerator (+4C), freezer (-20C, -30C) and freeze drier (-60C) using hanging drop technique in different concentration of sucrose and boric acid solution. Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4C and in fresh pollen. Freeze dried pollen (-60C) showed the highest germination percentage.
