It was found that Tb3+ ion could bond to the O and/or N group of the amides in the polypeptide chains of HRP, leading to a decrease in the enzymatic activity index of HRP.展开更多
以自繁的百合小鳞茎‘Siberia’为材料,研究不同因素处理下种球活力指数的变化特征。结果表明:-2℃、2℃低温处理诱导了抽薹,加快小鳞茎活力的表达,处理135~165 d 为最佳活力表达期;5~8 g 大规格的小鳞茎整体活力较强;培养周...以自繁的百合小鳞茎‘Siberia’为材料,研究不同因素处理下种球活力指数的变化特征。结果表明:-2℃、2℃低温处理诱导了抽薹,加快小鳞茎活力的表达,处理135~165 d 为最佳活力表达期;5~8 g 大规格的小鳞茎整体活力较强;培养周期超过5.5个月可获得较高活力的小鳞茎;二次回归正交旋转组合分析,37℃+3 h 热激处理下小鳞茎活力指数表现最优,热激处理为小鳞茎的低温春化提供了保护和储能基础。展开更多
