核桃果实性状与叶片性状的典型相关分析

本文利用典型相关分析的方法,研究了核桃六个果实性状(青皮厚度、青果重、坚果重、核壳厚度、出仁率、含油量)与八个叶片性状(顶叶长、顶叶宽、顶叶叶形指数、顶叶厚、侧叶宽、侧叶叶形指数、侧叶厚)之间的关系。结果表明,果实性状与叶片性状不存在显著的相关,且部分果实性状之间或部分叶片性状之间则具有较好的相关性。其中果实性状中青皮厚与青果重、青果重与坚果重、坚果重与出仁率和含油量达到显著相关水平;叶片性状中,顶叶长、顶叶宽、侧叶长、侧叶宽之间均具有显著的相关性,顶叶宽与顶叶厚有关,顶叶叶形指数主要取决于顶叶的宽度,顶叶厚与侧叶厚相关显著。性状相关性的研究,有助于利用相关选择提高核桃选种效率。

CANONICAL RELATIONSHIP BETWEEN FRUIT CHARACTERS AND LEAF ONES OF WALNUT

With canonical analysis the relationship between fruit characters including thinkness of green peel, weight of green fruit, weight of nut thinkness of hud, ates of kernel and oil content and leaf characters including length, width, leaf index and thinkness of uppermost leaf and lateral; eaf was studied. The results indicated that there was no significant relationship between the two groups of characters but there was significant relationship between some of the fruit characters such as thinkness of green peel with weight of green fruit, weight of green fruit with weight of nut and weight of nut rate of kernel and oilcontent, and also between some of leaf characters including length and width of uppermost leaf and lateral leaf. The study can help raise selection efficiency of walnut through application of correlated characters.
