Abstract:
The wild seeds of A.senticosus were pre-soaked with different concentrations of potassium nitrate (KNO3) solution for 48 hours，and then stratified at 18-22 ℃.The embryo rate，decay rate，and related physiological and biochemical indexes of the seeds were determined during the stacking process，in order to provide reference for the simplified cultivation of A.senticosus.The results showed that KNO3 pre-treatment significantly improved the activities of nitrate reductase and amylase，increased nitric oxide and soluble sugar content，and promoted the morphological post-ripening of seed embryo of A.senticosus. At the same time，the level of antioxidant enzyme activity was regulated，and the damage of active oxygen (ROS) to cells was alleviated and the content of MDA and decay rate of seeds was reduced.In conclusion，KNO3 pretreatment could effectively promote the morphological maturation of A.senticosus seeds，shorten the time of high-temperature stratification，and reduce the rate of seed deterioration during stratification.
