以6～7年生乐昌含笑多点种源试验林观测数据作为种源地理变异研究材料，通过多点方差分析及相关分析，并对生长性状进行聚类分析。结果表明，参试种源存在显著或极显著差异，说明种源地理变异真实存在；生长和形质性状与产地纬度存在负相关、与经度存在正相关，种源的生长和形质性状呈现随纬度降低、经度增加性状值逐渐增大的地理变异特点（除叶片大小外），来自纬度越低、水热条件越好的种源，其生长表现越好；参试种源可划分成丰产种源区、普通种源区和低产种源区，基本呈现纬度越低、丰产性越好的分布规律。
以6～7年生樂昌含笑多點種源試驗林觀測數據作為種源地理變異研究材料，通過多點方差分析及相關分析，併對生長性狀進行聚類分析。結果錶明，參試種源存在顯著或極顯著差異，說明種源地理變異真實存在；生長和形質性狀與產地緯度存在負相關、與經度存在正相關，種源的生長和形質性狀呈現隨緯度降低、經度增加性狀值逐漸增大的地理變異特點（除葉片大小外），來自緯度越低、水熱條件越好的種源，其生長錶現越好；參試種源可劃分成豐產種源區、普通種源區和低產種源區，基本呈現緯度越低、豐產性越好的分佈規律。

Studies of geographic variation pattern for Michelia chapensis were carried out based on two prove-nances trials established on 2005 and 2006.Results of multi-site ANOVA showed that significant difference existed among all tested provenances,indicating real geographic variation existed.Correlation analyses revealed that nega-tive correlation were detected between the grow,quality traits and the latitude of the provenance while the positive correlation existed between traits and longitude.The less the latitude and the larger the longitude,the traits were the larger,this pattern was suitable for all traits(except shape of leaf).With the better condition of water and heat,Provenances from lower latitude grew well.Based on the grow traits,cluster analysis was carried out and three groups were classified,which were the high,medium and low yield provenances area,showing that the rule of‘the lower of the latitude,the better of the yield’.
