摘要:

The germination percentage and tube elongation of freshly collected pollen of white sapote (a subtropical fruit tree) cultivars 'Aoshima', 'Vernon', and 'Maltby' were determined to identify the optimum agar medium conditions. Adequate germination percentage and tube elongation were obtained by using a 2% agar medium containing 5-10% sucrose at the incubation temperature of 20-30.DEG.C.. The use of a 2% agar medium containing 10% sucrose, with a 100-500ppm concentration of boric acid was effective for pollen germination. The germination percentage of the pollen which was stored for 45 days with silica gel (35% relative humidity) at 5.DEG.C. was almost the same as that of freshly collected pollen. The germination percentage of the pollen stored at -60.DEG.C. for one month was almost the same as that before the storage. It was possible to store the white sapote pollen without a decrease of germinability for one month under dry and low temperature conditions. Almost the same fruit-set percentage was obtained from hand-pollination with freshly collected pollen and pollen stored for about one month.
