不同大豆品种萌发期抗旱性鉴定方法研究
Study on the Methods for Drought Resistance Identification of Different Soybean Varieties at Germination Stage
摘要
Abstract
To select appropriate experimental conditions for the identification of drought resistance during the germination period of soybeans,varieties Longzhonghuang 601,Kenjiandou 15,Jiunong 29,and Changnong 16 were used as test materials.Germination tests were conducted using vermiculite and filter paper methods,with screening of germination beds through Internally Transcribed Spacer(ITS)sequence analysis.The germination rate,number of hard beans,and number of moldy beans were measured,along with selection for vermiculite moisture and PEG-6000 concentration.Results showed that the vermiculite method significantly reduced the types and quantities of molds in soybean germination tests,making it suitable for drought resistance identification during the germination period.At a vermiculite moisture of 170%and PEG-6000 concentration of 22%,significant differences in germination rates among the soybean varieties were observed,with fewer hard and moldy beans,providing reliable test data.These conditions are suitable for drought resistance identification tests during the soybean germination period.Under these conditions,the drought resistance of the 4 soybean varieties ranked from strongest to weakest as followed Longzhonghuang 601,Jiunong 29,Changnong 16 and Kenjiandou 15.关键词
