摘    要:于盛花期对66份种质进行湿害处理,结果表明:湿害对单秆型和分枝型种质的产量性状影响差异明显,对单秆型芝麻产量性状的影响(湿害指数值)大小依次为单株种子干重(69.18%)蒴果数(67.48%)有效果节数(49.10%)有效果轴长度(45.69%)株高(16.40%),对分枝性芝麻的影响依次为分枝有效果节数(65.96%)分枝蒴果数(64.73%)总蒴果数(52.01%)单株种子干重(49.92%)主茎蒴果数(41.66%)主茎有效果轴长度(37.57%)有效分枝数(34.21%)主茎有效果节数(20.12%)株高(15.43%);湿害对三蒴型芝麻的侧位蒴果影响较大,对单秆三蒴型芝麻的影响为侧位蒴果数(92.25%)中位蒴果数(50.25%),对分枝三蒴型芝麻的影响为分枝侧位蒴果数(92.86%)主茎侧位蒴果数(69.14%)分枝中位蒴果数(44.17%)主茎中位蒴果数(32.97%)。根据相对湿害产量可以将供试种质聚为耐湿与不耐湿二大类,不耐湿类型种质61份,占92.42%;耐湿类型种质5份,占7.58%,为竹山白芝麻、西平二郎花、阜南芝麻、嘉兴紧口黑和麻城黑芝麻,可作为耐湿种质加以利用。

关 键 词:芝麻  湿害  盛花期  株型  产量性状  耐湿性评价

Abstract:Sixty-six accessions sesame germplasm were treated by waterlogging at full flowering stage,and the results showed that there were obvious difference in yield characteristics of monaxial and ramification sesame germplasm:The waterlogging index of seed weight per plant(69.18%)>capsules per plant(67.48%)>capsule nodes per plant(49.10%)>length of capsule axis(45.69%)>height per plant(16.40%) in monaxial germplasm and that of branch capsule nodes per plant(65.96%)>branch capsules per plant(64.73%)>total of capsu...
Keywords:Sesame  Waterlogging  Full flowering stage  Plant type  Yield characteristics  Evaluation of water logging tolerance
