摘　　要：由于尖叶茶藨子种子休眠期长,为缩短其播种繁育时间,采用赤霉素(GA3)对宁夏尖叶茶藨子种子进行浸种处理。结果表明:1000 mg·L-1赤霉素浸种72 h的种子发芽率最高(63.33%),GA3浓度与处理时间对种子发芽率的影响达到极显著水平(P<0.01),两因素对种子发芽率的影响作用为GA3浓度>处理时间。Due to its long dormancy period,Ribes maximowiczianum seeds were soaked in Gibberellic acid in order to shorten the sowing and breeding time.The results showed that the treatment with 1000 mg·L-1 GA3 for 72 h produced the highest germination rate(63.33%)and the GA3 concentration and treatment time had an extremely significant effect on seed germination rate(P<0.01).Comparatively,GA3 concentration had a greater effect on seed germination than treatment time.
