Evaluation of Alkali Tolerance of Soybean Germplasm in West Liaohe Plain at Germination Stage
摘要
Abstract
To investigate the alkaline tolerance of soybean during germination in the West Liaohe Plain,237 soybean germ-plasms from this region were used as materials.By analyzing the effects of different concentrations of alkaline stress on five germination indicators(germination rate,germination potential,germination index,hypocotyl length,and root length),alkaline-tolerant germplasms at the germination stage were screened using comprehensive methods including variance analysis,princi-pal component analysis,and fuzzy membership function analysis.The results showed that,based on the comprehensive consid-eration of the alkaline solution concentration corresponding to 50%of the alkali damage index for germination rate,germina-tion potential,and germination index,100 mmol/L was determined as the optimal concentration for screening alkaline toler-ance of soybean at the germination stage.The inhibition degree of the five germination indicators by alkaline solution,from highest to lowest,was as follows:root length(77.16%),germination potential(57.03%),hypocotyl length(53.09%),germination index(48.47%),and germination rate(41.18%).Principal component analysis was performed on the five indicators,and the cu-mulative contribution rate of the first two principal components reached 83.927%,with the first principal component having a weight of 64.97%and the second principal component having a weight of 35.03%.D values were calculated based on the fac-tor weights,and the top five alkaline tolerant germplasms were screened as follows with Gongjiao11829-16(0.682),Ping'an001(0.624),Heinong531(0.512),Mengkedou27(0.500),and Dongsheng78(0.500).Further systematic cluster analysis classified the tested materials into 2 highly alkaline tolerant germplasms,94 alkaline tolerant germplasms,99 alkaline sensi-tive germplasms,and 42 highly alkaline sensitive germplasms.关键词
