摘　　要：种子休眠性是作物的重要性状之一。分别对刚收获和收获后35d的8个花生品种(系)种子进行发芽试验,以评价其休眠特性。结果表明,收获当天种子的发芽率和萌发率都可以作为评价种子休眠性的指标。4个普通油酸品种的休眠性极弱或无休眠期,高油酸品种开农176、开农301、开农71具有一定的休眠性。相关分析表明,种子休眠性强弱与油酸含量、油亚比表现为显著的正相关关系,与亚油酸含量表现为显著的负相关关系。Seed dormancy is one of the important traits of crops.In order to evaluate the dormancy characteristics,germination experiments were carried out on the seeds of 8 peanut varieties(strains)after fresh harvest and 35 days after harvest respectively.The results showed that germination percentage and germination rates can be used to evaluate seed dormancy.The dormancy of four common Oleic acid varieties showed weak or no dormant period,while high Oleic acid varieties(lines)Kainong 176,Kainong 301,Kainong 71 showed stronger dormancy.Correlation analysis showed seed dormancy had a significant positive correlation with Oleic acid content and O/L,and had a significant negative correlation with linoleic acid content.
