不同地区大麦品种苗期耐低氮性及聚类分析
Low-nitrogen tolerances of different-region barley varieties at seedling stage and their cluster analysis
摘要
Abstract
The hydroponics of 22 major barley varieties from different regions of China was carried out at their seedling stage under nitrogen stress and normal nitrogen supply conditions,and the comparative analysis and cluster analysis of the seedling characters' averages were made. The results showed that the dry shoot weight,dry plant weight,plant height,root length,tiller number and nitrogen use index were very significantly different between various nitrogen supply levels and between different varieties. The variation coefficients of the relative dry shoot weight,relative dry plant weight and relative tiller number were comparatively large under the nitrogen stress conditions and could be used as a standard of cluster analysis. The cluster analysis by using the software SPSS 17.0 indicated that those varieties could be divided into three groups and several subgroups.关键词
