| 摘 要： | 采用活体测定法，研究了硫、６－苄氨基腺嘌呤６－ＢＡ、不同生育时期的水分的温度对春小麦硝酸还原酶活性（ＮＲＡ）的影响。结果表明：硫营养对春小麦幼苗ＮＲＡ有明显的促进作用；６－ＢＡ具有提高春小麦幼苗ＮＲＡ的作用，１×１０－７ｇ／Ｌ的效应最为明显；适宜的温度和水分可提高春小麦植株体内的ＮＲＡ，而干旱胁迫会使ＮＲＡ急剧降低，抗旱品种的ＮＲＡ高于不抗旱品种

Effects of Sulphate, 6-Benzylaminopurine,Moisture and Temperature on NRA in Spring Wheat |
| |
| Abstract: | Effects of sulphate nutrition, 6-benzylaminopuirine (6-BA), temperature and moisture content on nitrate reductase activity (NRA) were studied with living plant determination on spring wheat. The result showed that sulphate nutrition accelerated NRA, 1×10 -7 g / L 6-BA increased NRA striking, the suitable home temperature and moisture content had the same effect, but drought sharply decreased NRA. Drought resistance varieties had higher NRA than those with drought susceptibility. |
