| 摘 要： | 为探求准确、可操作性强的油茶冠根比测评方法,本文应用SPASS软件对调查的油茶赣446、长林27、湘林210 3个油茶品种幼苗数据进行分析,结果表明：不同品种的地上部分重差异不显著（P〉0.05）,地下部分重、苗高和地径有显著差异（P〈0.05）;3个品种的地上部分重、地下部分重、苗高、地径四个指标均显著相关。建立了地上部分重和地下部分重的苗高、地径回归模型,通过地上部分重和地下部分重的回归模型计算的预测值估算冠根比,其结果经T检验与实际测量值无显著差异（P〉0.05）。 |

| Abstract: | Data of three varieties of Camellia oleifera Abel seedling Gan 446,Changlin 27 and Xianglin 210 were analyzed by SPASS to obtain an accurate and practical evaluation method.The results showed that the difference of shoot fresh weight was not large,while root fresh weight,height and ground diameter were significantly different and correlated among these three oil-tea seedlings.The regression models of shoot fresh weight and root fresh weight were built by height and ground diameter,and the predicting values of shoot-root ratio by the models were not remarkably different from test values. |
| Keywords: | shoot-root ratio Camellia oleifera Abel seedling test ground diameter |
