外源钙对淹水胁迫下牡丹生理生化特性的影响
Effects of Exogenous Calcium on Physiological and Biochemical Characteristics of Peony under Waterlogging Stress
摘要
Abstract
The peony is one of the top ten traditional Chinese flowering plants with the reputation "the king of flowers".In southern China however,the growth and development of peony are effected by the waterlogging.Spraying CaCl2 can alleviate waterlogging stress on the peony.It is of importance to study the physiological response of the peony to the application of calcium and to find out a way to mitigating the waterlogging stress.Peony was treated with different concentrations of CaCl2 under waterlogging stress and effects of CaCl2 on physiological and biochemical characteristics of peony under waterlogging stress were studied.The results showed that the chlorophyll content of peony under waterlogging stress gradually decreased,but the conductivity gradually increased,The activities of superoxide dismutase (SOD),anaerobic respiration (CAT,APX),and soluble protein content all increased first and then decreased,MDA content showed a gradual increase trend.The calcium could alleviate the waterlogging stress damage of peony and the most preferable concentration was 0.3 mmol · L-1.This study would provide a theoretical basis for the study of peony's waterlogging stress.关键词
