中文摘要 | 本研究對中國大陸 20 個東方蜜蜂群體工蜂的形態指標進行測定,主要研究結果 如下:20 個東方蜜蜂種群之間在形態標記上存在顯著或極顯著差異 (p < 0.05 或 p < 0.01),中國大陸東方蜜蜂形態指標存在豐富的遺傳多樣性。通過對形態指標相關性 分析表明 20 個東方蜜蜂種群的右前翅長、前翅寬、前翅面積、吻長與第 3、4 背板 總長均有極顯著相關 (p < 0.01);肘脈指數與其它形態指標均不相關 (p > 0.05),表 明肘脈指數是一個相對獨立的形態標記。20 個東方蜜蜂種群的 6 個形態標記和 8 項生態特徵數據的主成分分析結果表明,不同東方蜜蜂種群形態指標的差異主要反映 在包括形態標記和生態因素在內的 7 個主成分上,其累計貢獻率達 89.386%。主成 分分析結果表明東方蜜蜂種群間差異分析除了考慮蜜蜂個體形態特徵差異外,蜂群所 生活地區的環境因素也應被納入其中。 |
英文摘要 | Six main indexes of external morphology of 20 Apis cerana populations in China were described. The findings showed that there were significant differences (p < 0.05 and p < 0.01) among 6 characteristics in 20 populations in China, indicating that the genetic diversity of these 20 Apis cerana populations was abundant. The findings showed that significant differences (p < 0.01) existed in the length, width and area of the anterior wing,in the length of the proboscis and the length of terga 3 and 4; there was no difference between the cubital vein indexes and other characteristics (p > 0.05), indicating that the cubital vein index was an independent morphological feature. The principal component analysis (PCA) of the 6 main indexes of external morphological features and the 8 ecological features of the 20 populations showed that the difference among the morphological features was as a result of 7 principal components including both morphological and ecological features. The contribution rate of these two features was 89.386%. Thus, not only the morphological features but also the ecological features should be considered in principal component analysis. |
