掌叶覆盆子栽培性状的初步研究

Cultivated Characters of Rubus chingii

对引种栽培的野生掌叶覆盆子栽培性状的观察结果表明,掌叶覆盆子在植株性状、结实率、果实大小、单株产量等方面个体间差异极大。其中浅宽裂叶类型的掌叶覆盆子各主要经济性状和营养成分均明显优于深狭裂叶类型的掌叶覆盆子。作者认为掌叶覆盆子适合驯化栽培,野生种群有很大的选优潜力。

There was a greatly individual difference for Rubus chingii in botanical characters, fruit-bearing rate, fruit size and individual-tree yield. R. chingii could be divided into three forms: the shallowwide decomposite leaf form, the deep-narrow decomposite leaf; form and the three-lqbed leaf form. The main economic characters and the nutritive value of the former were superior to that of the latter both. R. chingii is fit to cultivate, which is a great potential in selection breeding.
