| 摘 要： | 以云南引种的46株元宝枫的果实为研究材料,对其果实的9个性状变异和各性状间的相关性进行了分析研究。结果表明,(1)果实性状的株间变异较株内变异显著;(2)果实各性状变异系数由大到小依次为空壳比率、果实厚度、种子千粒重、果实千粒重、着生痕长度、种子厚度、果实宽度、带翅果实长度、果实长度;(3)果实千粒重与种子千粒重呈高度正相关,与果实宽度、种子厚度、果实厚度呈显著正相关,与带翅果实长度、着生痕长度及果实长度呈低度正相关。种子千粒重除了与果实千粒重呈高度正相关外,还和带翅果实长度、种子厚度、果实厚度呈显著正相关,而且和果实宽度呈低度正相关。以此评选出引种地果实性状优良、产量高的元宝枫单株。

| Abstract: | Taking 46 Acer truncatum introduced to Yunnan as the study materials,the variance of 9 fruit characters and the correlation between different characters were analyzed.The study results indicated that: 1) the fruit character variance between different trees was more significant than that within the same mother tree;2) the variance coefficients decreased in the order of abortion ratio(R1),fruit thickness(D1),1000 seed weight(Q2),1000 fruit weight(Q1),length of growth vestige(L2),seed thickness(D2),fruit width(W1),length of fruit with wing(L1) and fruit length(L2).2) Q1 and Q2 was highly positive correlated,Q1was significantly positive correlated with W1,D2 and D1,Q1 was lowly positive correlated with L1,L2 and L3.Besides highly positive correlated with Q1,Q2 was significantly positive correlated with L2,L3 and D1,and was lowly positive correlated with W1.3) Based on the study, some superior Acer truncatum individuals with good fruit characters and high yield were selected out. |
