| 摘 要： | 为探索伯乐树不同种源的苗期生长规律,分析主要性状的遗传改良潜力,对3个伯乐树地理种源1年生播种苗苗高和地径性状进行了初步研究.结果表明:伯乐树从子叶出土到当年幼苗停止生长整个过程大体可分为出苗期、生长初期、速生期和生长后期4个阶段,地径生长比苗高生长约提早10d进入速生期,而晚10d停止生长.贵州2个种源的苗高和地径各...

| Abstract: | The height and diameter of annual B.sinensis saplings from three different geographical sources were surveyed to study their growth regulation and genetic improvement potentiality of main characters.The results showed that there were emergence stage,early growth stage,rapid growth stage and late growth stage from cotyledon emergence to stop growth of saplings in the same year,the diameter growth was 10 d earlier than sapling height growth and the stop growth of sapling diameter was 10 d later than stop grow... |
