涝害胁迫对茄子生理特性和果实产量的影响
Effects of Water-logging Stress on Physiological Characteristics and Fruit Yield of Eggplant
摘要
Abstract
In order to explore the effects of water-logging stress on physiological characteristics and fruit yield and quality of eggplant,pot and field experiments were conducted to study the changes of photosynthetic characteristics,chlorophyll content,protective enzyme activity,osmoregulator concentration and fruit yield and quality of eggplant treated with water-logging stress.The results showed that:after water-logging,plant growth was inhibited,plant height,stem diameter and plant width decreased significantly,which decreased by 58.40%,36.32%and 73.52%compared with normal irrigation treatment(ck).The chlorophyll content and photosynthetic efficiency of eggplant seedlings under water-logging stress decreased by 36.81%,54.08%and 47.41%,respectively.At the same time,protective enzyme activity,osmoregulator concentration and MDA content of eggplant seedlings were significantly increased,indicating that the membrane peroxidation of eggplant seed-lings was intensified under water-logging stress,the up-regulation of protective enzyme system and the increase of osmoregulator could enhance the ROS clearance ability of eggplant seedlings and main-tain the homeostasis in and out of cells.The seedlings were planted after water-logging stress,and the yield measured during the bearing period showed that the yield per plant decreased significantly,indi-cating that the decrease of chlorophyll content,photosynthetic efficiency and membrane peroxidation under water-logging stress resulted in the inhibition of plant growth and yield of eggplant.关键词
