| 摘 要： | 研究了低温沙藏和GA3处理对牡丹、芍药种子上胚轴休眠解除的效应,结果表明200 mg/L GA3浸泡'凤丹白'牡丹和芍药已生根种子2 h可缩短其发芽时间达107～111 d,且其发芽率、芽长、根长及苗重均优于对照或与对照处理相当;而GA3或低温沙藏处理对紫斑牡丹种子上胚轴休眠的解除效应相对较差.

| Abstract: | Effect of low temperature storage and GA3 on the epicotyls dormancy breaking of seeds of tree peony and herbaceous peony was studied in this paper.It revealed that it could shorten the germination time by 107 d to 111 days when the seeds of 'Fengdanbai' and herbaceous peony which had rooted were treated by 200 mg/L GA3,and the germination ratio,bud length,root length and seedling weight were better than those of CK or as good as those of CK. However,it was not enough efficient to epicotyls dormancy breaking of seeds of Paeonia rockii by low temperature or GA3. |
