本研究对湖北襄阳楸树种质资源库内收集保存的100份不同种质的叶片性状进行分析,结果表明:不同无性系间叶柄长度的变异最大,叶宽变异居中,叶长变异最小.同时,不同种质在叶长、叶宽、叶柄长等指标间均存在丰富变异,各指标差异均达到极显著水平.对各性状的相关遗传参数进行估算,不同种源内各无性系间除山东种源的叶长性状、安徽种源的叶宽和叶柄长性状差异不显著外,其它种源的各性状间都差异显著.其中无性系叶片宽长比的重复力最高,达60%,其次是叶片长度,其重复力为46.17%.
本研究對湖北襄暘楸樹種質資源庫內收集保存的100份不同種質的葉片性狀進行分析,結果錶明:不同無性繫間葉柄長度的變異最大,葉寬變異居中,葉長變異最小.同時,不同種質在葉長、葉寬、葉柄長等指標間均存在豐富變異,各指標差異均達到極顯著水平.對各性狀的相關遺傳參數進行估算,不同種源內各無性繫間除山東種源的葉長性狀、安徽種源的葉寬和葉柄長性狀差異不顯著外,其它種源的各性狀間都差異顯著.其中無性繫葉片寬長比的重複力最高,達60%,其次是葉片長度,其重複力為46.17%.

In this study,leaf traits of 100 different Catalpa bungei germplasms,which has been collected and conserved in Xiangyang Catalpa bungei germplasm resource bank in Hubei Province were investigated and analyzed.The result showed that leaf petiole length of different clones showed greater variation than their leaf width and length.There were abundant variation and great significant differences among the traits of leaf length,leaf width and leaf petiole length of the 100 different germplasms.Genetic parameters were also estimated;except the leaf length of germplasm from ShanG dong,the leaf width and the leaf petiole length of germplasm from Anhui,the leaf traits of different germplasms from Hubei,Henan,Shandong and Anhui provenance showed significant differences.The estimated repeatability of the leaf width-length ratio was 60% which was the highest,and that of leaf length was 46.17% which was the second.
