Abstract:
Taking 11 alfalfa varieties as experimental materials from home and abroad,in order to select the better salt resistance of alfalfa,the effect of different concentration of NaCl on the main seed germination traits including germination force,germination rate,plant height,root length,fresh weight and the content of chlorophyll were studied for 11 alfalfa varieties.The results showed that with the increase of NaCl concentration,the seed germination potential and seed germination force and seed germination rate both decreased gradually,the plant height and root length reduced significantly,and fresh weight and the content of chlorophyll both reduced greatly.The influence of high concentration of NaCl was more noticeable.Different alfalfa varieties had different reponse to NaCl stress.The comprehensive analysis of 6 seed germination traits was carried for 11 alfalfa varieties,and the result showed that the strongest salt tolerance was ‘Empress 2000’,while the weakest salt tolerance was ‘Jacklin’.
