摘要
为了筛选出适应广东地区的丰花型金花茶(Camellia nitidissima)优株,对广东省已经驯化种植10年的金花茶单株进行了调查。调查发现,金花茶种质的个体差异较大。逐步回归分析表明,冠幅和株高对丰花型金花茶的单株花量有直接影响,地径无直接影响。通过综合经济指标和生长指标,筛选出性状稳定的一级丰花型优株2株,二级优株2株。
In order to select the superior trees of floribundaCamellia nitidissima that were suitable to grow in Guangdong area,theCamellia nitidissima planted for10years were investigated in Guangdong province.The results showed that there was a significant difference among the tree individuals.By stepwise regression analysis,the crown width and height of floribundaCamellia nitidissima had direct effect on the amount of flowers,however,the ground diameter had no direct influence.Through the comprehensive economic index and growth index,two floribunda superior trees of first class and two superior trees of second class were selected of which the traits were stable.
