| 摘 要： | 盆栽条件下,以Na2SeO3为硒肥,通过底施模式研究不同浓度硒肥对铅胁迫下水稻幼苗部分生理特性的影响.结果表明,单一不同浓度硒肥处理的水稻幼苗根系活力和叶绿素含量先增后减,过氧化物酶(POD)活性先增后减再升,过氧化氢酶(CAT)活性和丙二醛(MDA)含量则先减后增;硒肥与铅复合处理的水稻幼苗根系活力先增后减再增,CAT活性先减后增,叶绿素和MDA含量先增后减,POD活性则先减后增再减,表明适量的硒肥对水稻幼苗生长发育有促进作用,且有拮抗重金属铅伤害的作用.

| Abstract: | A pot experiment was conducted to investigate the effects of application of Se on some physiological characteristics in leaves of rice seedlings under Pb stress. The results showed that under different concentrations of Se, the root activity and chlorophyll content of rice seedling increased first and then decreased, the activity of peroxidase (POD) increased first, then decreased and increased again; the activity of catalase (CAT) and content of malondialdehyde (MDA) decreased first and then increased.
