本文比较了GYBT突变体1103S与GYBT回复突变体96024的性状差异。结果表明:在自然变温及人工控温诱导下,1103S要表达间段失绿性状(Green-yellow band trait,GYBT),而96024不表达。两者的育性转换特性、多数农艺及谷粒性状无明显差异,但叶...本文比较了GYBT突变体1103S与GYBT回复突变体96024的性状差异。结果表明:在自然变温及人工控温诱导下,1103S要表达间段失绿性状(Green-yellow band trait,GYBT),而96024不表达。两者的育性转换特性、多数农艺及谷粒性状无明显差异,但叶片性状存在显著差异。两者的正常绿叶的叶绿素含量及a/b值、叶片游离氨基酸组分及含量也无明显差异。当GYBT表达时,1103S叶绿素含量比96024低77.49%,叶绿素a/b值比96024高58.99%。1103S和96024是研究GYBT较为理想的近等基因系。展开更多
