摘要
对"实践八号"返回式卫星搭载循化线辣椒种子SP2代农艺性状进行了调查,检测了变异性;并对SP2代辣椒碱提取率与其农艺性状的相关性进行了分析。结果表明:循化线辣椒种子经太空诱变处理后,SP2代处理在株高、茎粗、叶片、植株开展度以及果实纵径、横径、单果重及单株产量等方面均与对照表现出较大差异,且以正向变异居多;对SP2代辣椒碱提取率与株高、果纵径、植株径粗的相关程度较高,可将其作为品种选育的指标之一。
This study investigated agronomic traits for the Xunhua chili pepper seeds SP2 carried by＂Shijian-8＂recoverable satellite to detect the variability and analyzed the extraction rate of capsaicin SP2 correlation with agronomic traits.The results showed that after Xunhua chili pepper seeds SP2 treated by space-flight Mutation,in plant height,stem diameter,leaves,plants and fruit to carry out degree of longitudinal diameter,transverse diameter,fruit weight and yield per plant and the control aspects,such as to show a big difference and to a positive variation of the majority,this is the next step for future generations choose to provide a rich source of variation and selection space.Meanwhile,the capsaicin SP2 were extracted and were processed with correlation analysis its extraction rate and agronomic traits,the results showed that the Xunhua chili pepper＇s extraction rate of capsaicin associated with a higher degree of plant height,fruit longitudinal diameter and plant stem diameter,can be used as an indicator of breeding.
