| 利用植物生长调节剂Z-S对高产旱稻北农大65在三叶一心、拔节期和孕穗期进行叶面喷施,研究其对高产旱稻花后衰老的影响。结果表明:浓度为100 mg/kg Z-S叶面喷施后根系活力、根系SOD、CAT活性及可溶性蛋白质含量均明显高于其它处理;100 mg/kg Z-S喷施后旗叶可溶性蛋白质含量明显增加,而旗叶SOD、CAT活性较其它处理没有明显上升,高浓度处理(≥300 mg/kg)促进植株体内MDA累积,造成早衰。从产量方面看,100mg/kg的Z-S喷施能有效提高旱稻的产量和经济系数。 |

| A plant regulator named Z-S synthesized by our department was sprinkled on leaves of upland rice during three-leaf and one sprout stage,jointing stage and booting stage with different concentrations,respectively.The results showed: with sprinkling of 100 mg/kg Z-S,the root activity,SOD and CAT activities,soluble protein content were obviously higher than that with other treatments,soluble protein content of flag leaf increased obviously,but SOD and CAT activities increased not obviously in comparison with other treatments.Sprinkling with high Z-S concentration(≥300 mg/kg) resulted in MDA accumulation in plant and premature senility.Sprinkling with 100 mg/kg Z-S increased yield and economic coefficient of upland rice significantly (P<0.01). |
