| 摘 要： | 以60株表型优良的锥栗为材料,对14个调查性状进行分析 结果表明:树冠面积是影响单株产量的最主要因子,树高、发枝力、土壤肥力、感炭疽病、枝果比例等性状与单株产量也存在着显著相关;树冠面积、土壤肥力、感炭疽病、平均果重、枝果比例可用作高产植株选择的指标;通径分析是一种有效的分析方法 |
| 关 键 词： | 锥栗 相关分析 通径分析 |

| Abstract: | 60 excellent phenotypes of Castanea henryi are selected for yield study. Correlation analysis and path analysis of 14 characters indicate that crown area, tree height, branching ability, soil fertility, anthracnose infectivity and the proportion of vegetative and fertile branches have significant correlations with individual yield. Among these characters crownarea pursues the biggest direct effect on individual yield and a big indirect effect through. The study of determine coefficient and direct determine degree reveals the important role of crown area, soil fertility, anthracnose infectivity, mean fruit weigh and the proportion of nutrient and fruited branches in individual yielding. |
