李品种果实、果核、叶片之间的相关性测定尚未见报道。本试验通过对李品种果实、果核、叶片之间的相关性测定了解它们之间的相互关系,以便为李品种资源引种、育种亲本的选择及杂种的早期鉴定提供理论依据。 材料与方法 试材取自江苏省农业科学院园艺所李品种资源圃,1987年定植,砧木为毛桃,株行距4×4米,管理条件一致。果实在成熟适期分品种采收并进行有关性状的测量,叶片取于一年生枝条中部,叶面积的计算采用公式:(L×0.71)~2×0.57,L为叶长。
Li variety fruit, fruit nuclear, the determination of the correlation between the leaves has not been reported. In this study, the correlation between the fruit, the fruit core and the leaf of the plum varieties was studied to understand the correlation between them, in order to provide the theoretical basis for the introduction of the plum varieties, the selection of the breeding parents and the early identification of the hybrids. MATERIALS AND METHODS The test material was collected from the horticultural resource Lee garden of Jiangsu Academy of Agricultural Sciences. In 1987, the rootstock was peach, with a spacing of 4 × 4 meters and consistent management conditions. The fruit was harvested at the ripening stage and the related traits were measured. The leaves were taken from the middle of annual branches. The leaf area was calculated by the formula: (L × 0.71) ~ 2 × 0.57, and L is the leaf length.
