| 摘 要： | Zhengdan958 was taken as testing material and spraying different concentration 6-BA solution on the leaves surface at 3 leaves stage for studying the 6-BA effect on the nitrate reductase activity.The result showed that in 3 leaves stage,the NRA of leaves and leaf sheath was higher than that in root,the NRA of leaf sheath was higher than that of leaves.From bottom to apex,the NRA of the 1 leaf was higher than that of the 2,that of the 2 was higher than that of the 3.The NRA of leaves and leaf sheath and root had been changed by leaves surface spraying of 6-BA treatment.10 to 100 mg/kg 6-BA had promoted the NRA of leaves and had debased the NRA of root,but it had no regularly regulation on the leaf sheath.But the NRA of leaf and leaf sheath and root were promoted by 200 mg/ kg 6-BA treatment.
