盐胁迫对不同品种苜蓿种子发芽性状的影响
Effects of Salt Stress on Seed Germination T raits of Different Alfalfa Varieties
摘要
Abstract
In order to carry out the salt tolerance evaluation of alfalfa varieties and select the salt-tolerant alfalfa varieties ,the effect of different concentrations of NaCl (2 ,4 ,6 ,8 ,10 g/L ) on the main seed germination traits including germination rate ,seedling length ,root length ,seedling weight and root weight was studied for five foreign alfalfa varieties and four internal alfalfa varieties .Results showed that the main seed germination traits were greatly affected by NaCl stress .With the increase of NaCl concentration ,the seed germination rate decreased significantly , the seedling length and root length shortened greatly ,and the seedling weight and root weight also reduced gradually .The influence of high concentration of NaCl on seed germination traits was particularly noticeable .There was great difference among the alfalfa varieties in the response to NaCl stress .The comprehensive analysis of five seed germination traits was also carried out for nine alfalfa varieties ,and the result showed that Sandeli had the strongest salt tolerance ,while Yili alfalfa had the weakest salt tolerance .关键词
