摘要: 对全国21份野生三叶青种质资源进行生物学特性、扦插成活率与农艺性状考查,结果表明,不同种源三叶青生物学特性、扦插成活率与农艺性状存在显著差异,21份种源三叶青异地扦插平均成活率为697%,重庆与广西种源三叶青农艺性状表现优于浙江、江西、福建等种源;9个农艺性状简化为4个主成分,累计贡献率达906%;21个种源可以划分为4个类群,其中第Ⅰ类群与第Ⅱ类群三叶青农艺性状表现较好。通过叶片有无柔毛、茎形状与块根表面是否光滑等特性可初步区分浙江、湖南、湖北三叶青与广西、重庆等地三叶青;从农艺性状看,三叶青优良种质可优先在重庆、广西等种源中筛选;从供试的21个种源中,初步筛选出6个农艺性状表现良好的种源。

Abstract: Twenty\|one wild germplasms of Tetrastigma hemsleyanum from different provenances were collected. Biological characters, survival ratio of cuttage and agronomic traits were measured, counted, and analyzed. The results showed that there were significantly differences in the above characters among different germplasms. The average survival ratio was 697%. Besides, the agronomic characters of Chongqing and Guangxi germplasms were superior than those of Zhejiang, Jiangxi and Fujian germplasms. Whats more, nine agronomic traits were simplied to four principal components, whose accumulative contribution rate was 906%. In addition, twenty\|one germplasms were classifed to four groups, the agronomic traits of germplasms in group Ⅰ and group Ⅱ were superior. Pubescence on leaf, stem shape and tuber surface could be used to distinguish Zhejiang, Hunan, Hubei germplasms from Guangxi, Chongqing germplasms. In terms of agronomic traits, the superior germplasms of Tetrastigma hemsleyanum could be selected among Chongqing and Guangxi germplasms preferentially. Based on the work above, six superior germplasms have been selected preliminarily.
