摘　　要：为了解小麦硒生理机制,为小麦种质资源研究提供依据,采用硒酸钠直接喷施于土壤中的方法比较了高硒土壤(30 g/hm2硒酸钠)和低硒土壤(不施硒)上种植的不同品种小麦谷胱甘肽过氧化物酶活性。结果表明,喷施硒酸钠可明显提高小麦叶片谷胱甘肽过氧化物酶活性,不同省区小麦叶片的谷胱甘肽过氧化物酶活性不同。谷胱甘肽过氧化物酶活性不仅受土壤中硒含量的影响,还受生理和遗传等因素的限制。The leaf glutathione peroxidase activity of different wheat varieties planted in the soil with spraying 30 g/hm2 Na2SeO4 and the soil without applying Na2SeO4 was determined to provide the scientific basis for studying Se physiological mechanism and germplasm resources of wheat.The results showed that spraying Na2SeO4 could obviously improve the glutathione peroxidase activity of wheat leaves,there was difference in glutathione peroxidase activity among different wheat varieties.The glutathione peroxidase activity of wheat leaves is not only affected by Se content in soils,but also influenced by genetic and physiological factors.
