摘要
应用Askew和Blush的针叶树种子园开花物候重叠指数模型,在1987~1989年,对卢氏油松种子园31个无性系的花期物候观侧数据,做了异交、自交的重叠指数和种子园重叠指数的计算,为新建种子园时亲本的优化组配和现有种子园的去劣疏伐提供了重要参数。
An index of pbenological overlap in folwering developed by Askew and Blush was applied to 31 clones in the Chinese pine seed orchards located in Lushi county during 1987~1989. The index provided an important parameter for adjusting parental compositions inplanning new seed orchards and for roguing in first-generation seed orchards.
