| 摘 要： | 对银杏家系间的苗期生理生化和生长指标进行测定,并对生理生化指标与生长指标的相关关系进行研究。结果初步表明家系间生理生化指标、生长指标差异显著;叶片硝酸还原酶(NR)活性和单株生物量、苗高达到了极显著正相关水平;多酚氧化酶活性与单株生物量、苗高的相关系数达到极显著负相关水平。可以初步确定硝酸还原酶、多酚氧化酶为银杏苗木早期选择指标。 |

| Abstract: | In this paper,physiological biochemical indexes and growth characters of different Ginkgo biloba family were studied.The main results were as follows:the differences in physiological biochemical indexes and growth indexes were all significant.The correlation analysis showed that correlation coefficient between NR activity and height,seedling biomass both reached positive significant level,correlation coefficient between PPO activity and height,seedling biomass both reached negative significant level.So they... |
