NaCl单盐胁迫对大白菜种子萌发及幼苗生长的影响
Impact of NaCl Single Salt Stress on Seed Germination and Seedling Growth of Chinese Cabbage
摘要
Abstract
Using seeds of 5 different Chinese cabbage varieties as the test materials,and applying culture dish filter paper germination method,this paper explored the impact of NaCl single salt stress on seed germination and seedling growth of Chinese cabbage. The results showed that germination rate,germination vigor and vitality index of Chinese cabbage seeds declined to different degrees,the germination time and process were postponed;NaCl stress had significant inhibitory effect on the seed germination,specifically,inhibitory effect of 0.4 mol/L NaCl on germination rate of Chinese cabbage seeds achieved 50% and above,and germination vigor of seeds of 5 test varieties was zero under the 0.8 mol/L NaCl stress. In terms of seedling growth, fresh weight and dry weight of shoots and roots of all 5 varieties were influenced to different degrees by salt stress of different concentrations,root and shoot length declined with the increasing concentration,i.e. salt stress also inhibited the growth of seedlings.关键词
