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.
