GERMINATION CAPACITY OF STORED POLLEN OF FICUS CARICA (MORACEAE) AND THEIR MAINTENANCE
SHAUKAT ALI KHAN AND ANJUM PERVEEN
Abstract: Present investigations pertain to pollen germination and viability of Ficus carica L. (Moraceae) for up to 48 weeks. Pollen germination was made by hanging drop technique in different concentration of sucrose and boric acid solutions (10%-100%). The stored conditions are refrigerator, freezer, in vacuum over silica gel and in organic solvents (acetone,benzene, and chloroform). Pollen stored at low temperature (-30°C, -20°C) showed better germination percentage compared to pollen stored at 4°C & fresh. The study indicates that 30% and 40% solutions favoured pollen germination. Benzene showed more germination than acetone and chloroform.
