POLLEN GERMINATION CAPACITY OF THREE MANGO CULTIVARS (MANGIFERA INDICA L., ANACARDIACEAE) FROM PAKISTAN
SHAUKAT ALI KHAN AND ANJUM PERVEEN
Abstract: Pollen germination capacity and viability of 3-mango cultivars viz., Chaunsa, Dasheri and Langra were investigated up to 48 weeks. Pollen germination was standard by hanging drop technique in different concentration of sucrose solutions (5%-50%) with 1% agar and 0.001% boric acid. The stored conditions were refrigerator (4ºC), freezer (-20ºC, -30ºC), freeze drier (-60ºC), in vacuum over silica gel and in organic solvents (acetone, benzene, chloroform). Pollen stored at low temperature showed better germination percentage compared to pollen stored at 4ºC and fresh. Among three cultivars variety langra showed better pollen germination at all stored conditions except at -20ºC. Variety chaunsa and dasheri also showed good germination of pollen.
