摘要
对2010年贵州初选的有结实的20株榉树优树进行苗期对比试验。结果表明:优树子代间在苗木高生长、地径生长方面存在明显的遗传差异;优树子代内也存在个体间的遗传差异。综合初选优树子代苗木高生长和地径生长指标,有6个优树子代在苗期生长快。
Contrast tests in growth of seedlings of 20 plus trees of zelkova schneideriana which primary selected in Guizhou province in 2010. The results were summarized as follows : the seedling hight,ground diameter had extremely significant genetic differences among them,and there are also genetic differences in the offsprings of one individual plus tree. According to the index of height and ground diameter,there are 6 offspring grow faster at seedling stage.
