Plant cell wall in the face of adversity will appear thicker,to withstand the adverse environment.It was a preliminary identification of the cell wall due to the formation of the lignin deposition.At present,the synthesis of lignin that is not only a means,but Phenylalanine Ammonia-Lyase (PAL) and Cinnamic acid 4-Hydroxylase (C4H),such as enzyme in the synthesis played a very important role.As a result,this experiment with wild Prunus mongolia Maxim used to study drought stress in different ecological conditions,the impact of the body of its PAL and C4H activity.The results showed that:when subjected to drought stress,Prunus mongolia Maxim almond leaves with the activity of PAL and C4H drought stress increased gradually increased,and in arid regions in Prunus mongolia Maxim almond leaf PAL and C4H activity than the relatively arid region.PAL and C4H activity and plant drought resistance was positive correlation between.
