铁冬青园林应用优树标准和优树选择

Elite Individual Standard and Selection of Ilex rotunda in Landscape

以乡土树种铁冬青为研究对象,在园林应用上,以生态学、资源开发利用潜力、生物学、株形指标进行评价和选择优树;生态学、资源开发利用潜力和株形指标为基础指标;生物学指标为决选指标,包括:挂果枝比率、果序挂5果以上的比率、果体直径平均值,采用基准线法进行优树选择和优树分级。

The local tree species Ilex rotunda in landscape was studied in this paper. The indexes of ecology, developmental potential, biology and individual shape were applied to assess and select the elite individuals. The basal indexes were ecol- ogy, developmental potential and individual shape. The biological index was for the final decision, including the ratio of fruiting branch, the ratio of infructescenee with five fruits, the average fruit diameter. The Datum Line Method was applied for elite individual selection and rating.
