摘要
在 11年生泡桐杂交种试验林中选择有代表性的单株 15 0棵 ,研究了 2 3个与干形相关的性状 .结果表明 :泡桐接干类型分为难接干、徒长枝接干、连续接干 3种 ;2 3个性状中有 19个性状在不同接干类型间差异极显著 ;干形性状的前 3个主导因子分别为接干材积、主干材积和主干尖削度 .
One hundred and fifty representative paulownia trees were observed in eleven year old paulownia hybridization in order to research the characteristics related to stem form.The results are as follows:paulownia joint stem can be divided into three kinds:difficult joint stem,discontinuous joint stem,continuous joint stem.Nineteen characteristics out of twanty three ones are significantly different.The three principal factors affecting the stem form characteristics are volume of joint stem,volume of primary stem and the tapering grade of the primary stem.Continuous joint stem is the direction of paulownia stem form selection.
