水分胁迫对黄秋葵生理以及光合特性的影响
Effect of Water Stress on the Physiological and Photosynthesis Characteristic of Okra (Abloschus esculentus L.)
摘要
Abstract
We conducted a study of the effect of water stress on gowth,physiological metabolism and photosynthesis in okra.Four different water stress treatments (watering once per 30d,watering once per 15d,watering once per 7 d,watering once per 3 d) were investigated based on pot experiments.The agronomic traits of plants in okra during seeding stage,flowering stage and harvesting time,grain yield and its components,physiological and biochemical indexes and photosynthetic traits of okra were determined in this study.The results showed that with the enhancement of drought stress intensity,the agronomic traits,grain yield and its components of okra in each growth stage were reduced.Even the plant was failed by severe dehydration.Furthermore,the stomatal conductance and net photosynthesis rate were reduced with the increasing of the intensity of water stress.The chlorophyll content in blade increased first and then decreased.Soluble protein,proline,soluble sugar and malondialdehyde content of okra were also decreased with the increasing of the intensity of water stress.关键词
