以3年生“香玲”核桃幼树为材料,调查分析了结果母枝与结果枝间的性状相关性。结果表明,3年生“香玲”核桃幼树结果母枝长度集中在20.1~60.0cm,母枝粗度集中在10.1~25.0mm;结果枝长度集中在5.1~45.0cm,结果枝粗度集中在5.0~11.0mm;结果母枝长度和粗度与其抽生的结果枝个数、结果枝长、结果枝粗、坐果数及复叶数等5个性状间均呈极显著正相关,说明结果母枝是构成产量的重要因素,其生长发育的好坏,决定了结果枝的数量和质量。
A 3-year-old “Hong Ling ” walnut saplings were used as materials to investigate the correlation between the results of the main branch and the fruiting branch. The results showed that the length of main branches of 3-year-old “Hongling” walnut trees concentrated in 20.1 ~ 60.0cm, the thicknesses of main branches concentrated in 10.1 ~ 25.0mm; the length of branches was 5.1 ~ 45.0cm, Concentrated in the range of 5.0 ~ 11.0mm. The results showed that there were significant positive correlations between the length and thickness of the female branches and the number of the branches, the results of the branches, the thick branches, the number of the fruit sets and the number of the composite leaves. The results of the parent branch is an important factor in yield, its growth and development is good or bad, determines the outcome of the number and quality of branches.
