摘要：

"Growth of pollen tube in the pistil of white sapote 'Florida' flowers was observed using a fluorescence microscope. The number of hours required for a pollen tube to penetrate an ovule was investigated at 10,15, 20, 25, and 30degC. Pollen tube penetrated an ovule within 8 hours at 30degC and the penetration took a longer time at lower temperatures. The effective pollination period (EPP) in white sapote was estimated from the results of fruit set brought about by hand pollination at different times after anthesis. The EPP was 15 days on flowers in March and the period was shorter in April when temperatures increased. Observations of the changes in the stigma coloration showed that the EPP appeared to continue until the stigma became brown."
