摘要

对福建五一林场马尾松 ( Pinus massoniana Lamb. )种子园 20个无性系的种子品质及单株球果产量进行了统计分析 ,结果表明: 无性系间在种子品质上存在着极显著差异 ,而无性系内除种子千粒重差异不显著外 ,其他性状 (果径果长单果重和单果出籽数 )差异极显著20个无性系的单株球果产量大多逐年上升同时对不同年份无性系结实的稳定性进行分析 ,划分出较稳定的无
性系和较不稳定的无性系
,评选出了种子高产品质优良的无性系
 

Abstract

The seed traits and cone yields o f a single tree of Pinus massoniana Lamb. were analyzed in Forest Farm of Zhangping Wuyi. The result show ed that variation between clones of seed traits was more significant and variation within clones of the seed traits was also more significant except 1000-seed weight. With the age grown up, the cone yields of a single tree of 20 clones increased by years. The stability of cone production at different ages was analyzed. Finally , the clones with high genetic quality and ample production of seeds were selected out.
