| 摘 要： | 对山核桃母树枝条进行不同程度的修剪，比较不同修剪程度下萌芽、抽枝、出穗的数量及质量，并对其相关性进行分析。结果表明：存芽数与修剪程度呈显著负相关，修剪越轻存芽数量越多；成枝数和有效枝条数与修剪程度呈正相关，重度修剪的成枝数量最多，有效穗条亦越多。美国山核桃采穗圃母树修剪中，建议采用重度修剪方式。

| Abstract: | Different intensities of pruning were conducted to the branches of maternal-scion Carya iUinoensis trees to compare the quantity and quality of its bud germination, sprouts and the cuttings obtained, and to conduct the correlation analysis so as to study the influence of pruning on the important indexes of C. illinoensis. The results showed that the number of deposit buds was significantly and negatively correlated with the pruning intensity, i. e. , the lighter the pruning was, the more deposit buds would be. There was positive correlation between the number of branches and the effective scions to be formed and the pruning intensity, i. e. , the heavier the pruning was, the more branches would be formed＇ and more effective scions might be prepared. Heavy pruning was recommended for maternal C. illinoensis trees in the maternal-scion plots. |
