用隶属函数值评价小黑麦在萌发期及幼苗期对复合盐胁迫的耐性
The Evaluation of Mixed Salt Tolerance in Triticale During Seed Germination and Seedling with Subordinate Function Value
摘要
Abstract
[ Objective] The purpose of this study was to provide more information for the research based on physiology in triticale under salt stress and salt tolerant breeding. [ Method ] Four spring triticale varieties were employed. The effects of the mixed salt stress with different concentration of NaCl and Na2SO4 on seed germination and seedling indicators of triticale were studied. Salt - tolerance was evaluated comprehensively by using membership function method. [ Result] With the increasing of salt concentration, the germination percentage of seeds, seedling fresh weight, dry weight on ground, dry weight of roots, plant height and root numbers of 4 spring triticale varieties tended to be decreased, which showed a negative correlation between salt concentration. Under the salt stress, the main roots showed a tendency of first going up and then dropping. [ Conclusion] According to the comprehensive evaluation of salt resistance, the rank of 4 triticale varieties tested was Xinxiaoheimai 5 ＞ Xinxiaoheimai 1 ＞ Xinxiaoheimai 3 ＞ Xinxiaoheimai 4.关键词
