| 摘 要： | 分别比较了12个薄壳山核桃无性系果实、核果以及产量之间的差异,分析了各无性系果实性状、核果性状以及产量等12个指标之间的相关性.结果表明:薄壳山核桃果实性状、核果性状以及产量等12个指标在各无性系间均存在极显著的差异;12个无性系果实性状总体变异系数从大到小顺序依次为:单株鲜果产量(变异系数CV为61.06%),果质量(30.18%),果皮厚(25.60%),果高(16.48%),果型指数(13.77%),果径(10.54%),这与12个无性系核果性状总体变异系数的大小顺序(单株核果产量,核质量,出核率,核高,核型指数,核径)是一致的;不同无性系果质量与核质量(果径与核径)、果高与核高(果型指数与核型指数)分别呈显著、极显著正相关,因而可以根据薄壳山核桃果实的外形及大小来初步判断核果的形状和大小.

| Abstract: | Fruit characters,nut traits and yield of 12 pecan(Carya illinoensis) clones were compared and the correlation between them was analyzed.The result showed highly significant difference among the clones in the 12 indexes studied.The CV(coefficient of variance) of the fruit characters appeared in the order of fresh fruit yield per tree > fruit weight > peel thickness > fruit height > fruit shape index > fruit diameter,being 61.06%,30.18%,25.60%,16.48%,13.77% and 10.54%,respectively.A similar order was observed... |
