磷化氢对水稻种子萌发过程及生理特性的影响
Effects of Phosphine on Germination and Physiological Characteristics of Rice Seeds
摘要
Abstract
[Objective]This study aimed to investigate the effects of phosphine on germination and physiological characteristics of rice seeds. [ Method] Simulation environments were conducted to study the effects of high-level phosphine on germination status and physiological characteristics of rice seeds and explore the early environmental and ecological effects of phosphine on rice growth in phosphorus cycle of paddy field. [Result] Eexperimental results showed that the increase of phosphine concentration in the environment results in the decrease of germination rate and germination potential by 11.11% and 19.71% , respectively. In addition, the activities of catalase (CAT) and peroxidase (POD) were reduced to 94.35% and 92.61%, respectively; the content of malondialdehyde (MDA) was maximally increased by 29. 11% , indicating that both germination potential and growth condition of rice seeds were inhibited under conditions of high-level phosphine. [ Conclusion] This study provided theoretical basis for investigating the effects of phosphine on germination of rice seeds in the natural environment.关键词
