【摘要】 通过对4个泰山板栗优系的单株产量及其产量构成因子的关联度分析,得到结果母枝数、结果母枝抽生结果枝数、结果枝结棚数、单粒重、干周、树冠投影面积6个重要相关因子;对入选的6个因子进行通径分析,明确了影响板栗产量形成的4个主要因子为:结果母枝数、结果枝着生栗棚数、树冠投影面积和结果母枝抽生结果枝数,上述4个指标可以作为板栗早期丰产鉴定的主要参数。更多还原

【Abstract】 The correlation and path analysis of main agronomic characters of chestnut was studied in this experiment.The result showed that not only the numbers of mother branches,branches with nuts and nuts of a branch but also the average weight of nuts,the diameter of stem and the area of tree.The result of path analysis of these 6 factors showed that the number of the mother branches and the nuts of a branch,the area of tree,the number of branches with nuts were the main factors effected the output.更多还原
