苹果鲜花脱药时间对花粉粒萌芽率有明显影响，试验设９个脱药时段，以３０小时内脱药的花粉萌芽率高，为６３．１％～５８．７％；３６小时脱药的花粉萌芽率明显降低，为４１．２％，脱药时间越迟，萌芽率越低。
The removal time of apple flowers had a significant effect on the germination rate of pollen grains. The experiment set 9 extraction periods, and the germination rate of the pollen degummed within 30 hours was 63.1% -58.7%. The 36-hour drug-free Pollen germination rate was significantly reduced to 41.2%, the later the drug withdrawal time, the lower the germination rate.
