摘　　要：以三系杂交籼稻汕优63为对照,系统研究了两系杂交籼稻扬两优6号高产的源库特征。结果表明:扬两优6号库容量大,填库能力强,光合生产能力强,物质积累量多且运转顺畅,具有源、库、流同步协调增长的特征。扬两优6号特别具有颖花高结实和籽粒高充实的高产特征,是两系杂交籼稻结实性能的重大改良。With three-line hybrid rice Shanyou 63 as control,the high-yield characteristecs of source and sink in two-line hybrid rice,Yangliangyou 6 was studied.Results showed that,compared with Shanyou 63,Yangliangyou 6 was superior in sink capability and its sink filling ability,photosynthetic ability,accumulation and translocation of photosynthetic product,synchronous increase of source-flow-sink.Yangliangyou 6 had excellent characters of high percentage of filled grain and grain-filling rate,which was an importan...
