摘要:
为探讨2种不同基因型耧斗菜的耐旱性，用5%、10%、15%、20%、25%的PEG6000溶液处理耧斗菜种子，研究PEG6000模拟干旱胁迫对2种不同基因型耧斗菜萌发的影响。结果表明：干旱胁迫抑制了耧斗菜种子的萌发，2种不同基因型材料的种子发芽率、发芽势、相对发芽率、发芽指数均显著降低（P<0.05）。低浓度PEG6000促使萌发高峰期提前，而且加快了种子萌发进程，高浓度则反之。在相同的PEG6000浓度处理水平下，白鹭耧斗菜表现出的耐旱性强于黄凤耧斗菜。
Abstract:
In order to explore the drought resistance of two different genotypes of Aquilegia vulgaris,the seeds of Aquilegia vulgaris were treated by 5%,10%,15%,20% and 25% of PEG6000.The results showed that the germination rate,germination potential,relative germination rate and germination index of seeds with two different genotypes were significantly decreased under drought stress（P<0.05）.In addition,low concentration of PEG6000 promoted the germination peak earlier,and accelerated the process of seed germination,while high concentration was opposite.At the same concentration of PEG6000,Aquilegia vulgaris of Bailu showed stronger drought tolerance than Aquilegia vulgaris of Huangfeng.
