Principal Components and Membership Function Analysis of Low Phosphate Tolerance at Seedling Stage in Soybean
摘要
Abstract
The low phosphate tolerance of 20 soybean genotypes were evaluated by principal components and membership function analysis. Results showed that the 11 significantly different low phosphate tolerance indexes could be classified into three principal components induding:shoot biomass factor,phoshorus factor,and root system factor. The low P tolerance( from strongest to weakest) of tested soybean were as follows: Gantai, Wuheqihuangdou,7650, Xiangdou No. 4,Xianjin No. 2,Su 88M-21, Peking, Gaozuoxuan No. L.Kefeng No. 1, Xinyixiaoheidou, Nannong 1138-2,94-156,87-23, He 84-5, Bogao, RN-9, Tongshanbopijia, Wan 82-178, Xiangqiudou No. 2, Dianjiangzaohuangdou.关键词
