[目的]探讨磷化氢对水稻种子萌发过程及其生理特性的影响。[方法]通过模拟研究环境中高浓度磷化氢对水稻种子萌发过程及其生理特性的影响，探讨水稻土中磷循环过程中磷化氢对水稻生长的初期环境生态效应。[结果]环境中磷化氢的存在导致水稻种子的发芽率、发芽势分别下降11．11％、19．71％；同时水稻种子萌发过程中的过氧化氢酶（CAT）活性减少至94．35％，过氧化物酶（POD）活性减少92．61％，丙二醛（MDA）含量最大增长29．11％。说明水稻种子在高浓度磷化氢影响下下，发芽力及生长状况都受到了抑制作用。[结论]该研究为自然界中磷化氢对水稻种子萌发过程影响的研究提供了理论依据。

[Objective] This study aimed to investigate the effects of phosphine on germination and physiological characteristics of rice seeds. [Method] Simulation envi- ronments were conducted to study the effects of high-level phosphine on germination status and physiological characteristics of rice seeds and explore the early environ- mental and ecological effects of phosphine on rice growth in phosphorus cycle of paddy field. [Result] Experimental results showed that the increase of phosphine con- centration in the environment resulted in the decrease of germination rate and ger- mination 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%, respec- tively; the content of malondialdehyde (MDA) was maximally increased by 29.11%, indicating that both germination potential and growth condition of rice seeds were in- hibited under conditions of high-level phosphine. [Conclusion] This study provided theoretical basis for investigating the effects of phosphine on germination of rice seeds under natural environment.
