添加水杨酸对干旱胁迫下3种豆科植物的影响
The Effect of Adding Salicylic Acid on Three Leguminous Plants under Drought Stress
摘要
Abstract
The study investigates the physiological responses of three leguminous plants under simulated drought stress of different concentrations.Using Astragalus sinicus L.,Medicago sativa L.,and Trifolium repens L.as materials,the materials were divided into two groups:one group without salicylic acid treatment,and the other group treated with 0.5 mmol·L-1 salicylic acid(SA).Two concentrations of polyethylene glycol(PEG),0％and 10％,were used to simulate drought stress on seedlings of the three leguminous plants.The study found that as the concentration of PEG increased,the fresh weight of seedlings of the three leguminous plants all decreased,but the change in dry weight varied among plant species.Salicylic acid treatment had a positive effect on improving the dry weight of Medicago sativa and Trifolium repens,but had a slight negative impact on the dry weight of Astragalus sinicus.The chlorophyll content showed an increasing trend under drought stress,but it decreased under salicylic acid treatment.关键词
