氯离子通道抑制剂对苹果叶片氯化钾伤害的缓解效应
Mitigating Effects of Chloride Channel Inhibitors on Potassium Chloride Injury in Apple Leaves
摘要
Abstract
To alleviate the damage of high concentration KCl to apple leaves,this study uses young'Red Fuji'apple trees as materials,and sprays KCl solutions(added the ion channel inhibitors of primidone,abamectin,ethiprole and phenyl benzoate chlorine,respectively.)on the leaves.Then it analyzes the photosynthetic performance,antioxidant capacity and chlorine ion content of the leaves.The results show that spraying 75 mmol·L-1 KCl alone causes chlorosis and scorching of leaf,significantly reduces net photosynthetic rate and water use efficiency of leaves,and increases levels of reactive oxygen species(ROS)and malondialdehyde content.After adding the four types of chloride channel inhibitors to KCl solution,the phenomena of leaf chlorosis,the decrease of photosynthetic rate and water use efficiency,and peroxidation damage are all alleviated to varying degrees.Among them,the addition of primidone significantly reduces the chloride ion content of leaves under high concentration KCl treatment,indicating that primidone can alleviate the damage of high concentration KCl to leaves by reducing chloride ion accumulation.关键词
