Abstract
[Objective]The aim was to provide the theoretical basis for drought resistant cultivation and breeding of drought resistant variety of alfalfa.[Method]With alfalfa as the material and the treatment with normal water supply as CK,the changes of ABA content in leaves and roots of alfalfa were studied.[Result]Under the condition of normal water supply,ABA content in roots of alfalfa was higher than that in leaves.After 3 h of drought stress,ABA content in leaves of alfalfa was significantly higher than that of CK,and then it showed decreasing trend.After 6 h of drought stress,ABA content in roots of alfalfa was the highest,being more than 3 times of that of CK.With the delay of drought time,the RWC in leaves of alfalfa was decreased,and it was decreased from 82.5% to 56.4% after 3 h of drought stress.After 6 h of drought stress,the RWC in leaves of alfalfa only was 33.5%,but that in roots of alfalfa changed a little.[Conclusion]Under water stress,the ABA in roots of plant had regulatory effect on growth and development of aerial part of plant as signal molecule.
