摘　　要：在室温和4℃下,对JL4和CC3开花前一天的花药进行短期保存,结果发现:室温有利于散粉,散粉情况好的萌发率较高,处理2这一保存方式下的散粉情况和萌发情况均最好。将辐射后的花药用处理2进行验证,结果证明其适用黄瓜辐射后花粉的短期保存。Two genotypes of cucumbers(JL4 and CC3) were used to study for short time storage of anthers under eight designed conditions at room temperature(25-27℃) and 4 ℃,respecitively.The results showed that the anther opened well at toom temperature,and treatments 2 and 8 were much better than the other treatments.The conditions good for pollen shedding were also good for germinating.Multiple comparison analysis among germination rates of treatments 2,8 and control showed no significant difference between treatment 2 and control,but both treatment 2 and control were significantly higher than treatment 8.Anthers that irradiated in the morning one day before anthesis were used to test the best storage method and the results proved that the treatment 2 was good for short time storage of irradiated cucumber anthers.
