| 摘 要： | 采用在美国育成的几个株系，并以常见的本地栽培品种‘桂花香’作对照，对刚进入结果幼树的枝梢开花习性，枝梢生长情况与开花坐果关系，以及树冠不同部位的枝梢开花与坐果进行调查分析。结果表明：对全部参试材料而言，末级梢的长、粗度区间分别以20．0～59．9cm和0．5～1．49cm的雌花量和坐果数较高；株系95—1—26和95—1-9雌花着生部位较其它3个株系或品种的节位高出一倍以上，其平均着生节位与末级梢平均节位基本上相等；从树冠立体分布上看，其外围和树冠上部水平方向中膛结果数较多，但对于每个株系来说，又存在一定的差异。以上研究结果对幼年结果树的枝梢培养、树体的整形修剪，以及达到早期丰产具有实践指导意义。

| Abstract: | Young trees of selected chestnut individuals,'Guihuaxiang' used as control,were studied on flowering and fruiting relations with shoots,characters of shoot growth,and proportions of a canopy.The results as follows:length and thickness of terminal shoots with scales of 20.0-59.9 cm and 0.5-1.49 cm,respectively,had higher number of female flowers and fruiting sets;Nodes which female flowers grew on for 95-1-26 and 95-1-9 from base of shoots were two times higher than ones of the other three;Fruiting sets were higher on the periphery and in the middle of upper canopy for all accessions,but there exited differences among individuals.It could provide practical use for fostering fruiting shoots,training and pruning,and getting higher production for young fruiting trees. |
