摘　　要：以甘薯品种徐薯18为对照(CK),采用生长分析法,通过田间试验,对贵州6个甘薯地方品种的生长性能进行了分析。结果表明:品种"道真白皮苕"的块根和茎叶鲜重明显高于CK的;品种"道真白皮苕"、"紫云红心薯"的干物质积累量、LAI、RGR及NAR均明显高于CK的。因此在供试的6个甘薯地方品种中,道真白皮苕和紫云红心薯的物质生产性能较优。In this study , sweet potato variety Xushu 18 was used as the control （ CK） , and the growth performances of 6 local sweet potato varieties in Guizhou were studied through field tests by using growth analysis method .The results showed that sweet po-tato variety “Daozhen white-peel sweet potato” had significantly higher root tuber fresh weight and stem plus leaf fresh weight than CK.The dry matter accumulation , leaf area index , relative growth rate and net assimilation rate of varieties “Daozhen white-peel sweet potato” and“Ziyun red-inside sweet potato” were obviously higher than those of CK .So, among the tested 6 local sweet po-tato varieties,“Daozhen white-peel sweet potato” and “Ziyun red-inside sweet potato” possessed better growth performances .
