| 摘 要： | 为系统揭示红楠主要表型与苗期性状地理种源变异规律,对红楠天然分布区9个种源的果实、叶片和种子的8个主要表型性状,以及苗高、地径2个苗期性状进行分析.结果表明,红楠叶片、果实、种子表型性状在种源间的差异均达到了极显著水平.纬度、年均温、年均无霜期和海拔是影响红楠表型性状的主要因子,其中果实大小、种子质量与纬度呈显著正相关...

| Abstract: | The main objectives of this study were to investigate geographic variation in main phenotypic traits and the seedling traits of Machilus thunbergii from nine provenances.Eight phenotypes of leaves,fruits,seeds,and two growth traits were included.Results showed that there were highly significant differences in phenotypic traits such as leaves,fruits and seeds between different provenances.The latitude,annual average temperature,annual average frost-free period and altitude were the main factors affecting the... |
