不同水稻品种萌发期锑耐性综合评价
摘要
Abstract
Rice is an important food crop.Antimony toxicity seriously affects the growth and development of rice.In order to screen antimony tolerant rice varieties,the seeds of 8 rice varieties were selected in this study,and their root length,bud length,plant height,germination energy and germination rate were measured at germination stage.Antimony tolerance at germination stage was identified by membership function,principal component analysis,cluster analysis and regression analysis,a comprehensive evaluation model for antimony tolerance during germination was established,and appropriate evaluation indexes were selected.The results showed that the dispersion degree of the nine related indexes was different,the coefficient of variation ranged from 18.66%～61.81%,and the data differences of each trait between the eight varieties reached a significant level.Principal component analysis transformed 9 individual indicators into 3 new comprehensive indicators,with a cumulative contribution rate of 85.82%.Through cluster analysis,the eight varieties were divided into 1 strong antimony tolerance variety,3 medium antimony tolerance varieties and 4 antimony sensitive varieties.关键词
