摘要
采用两对近等基因系在两个地点的试验研究表明,与正常苞叶近等基因系比较,窄卷苞叶系棉花现蕾、开花、吐絮期较迟,前期单株果枝、果节、结铃数较少,但中后期现蕾、开花、成铃增多,吐絮集中,因而两者霜前花量(率)无显著差异。
Effect of frego—bract gene on cotton earliness was investigated using isogeniclines on each of two genetic backgrounds.As compared with the isogenetic lines with a normalbract,the square,flowering and boll opening were delayed in the frego—bract lines with theresults of fewer fruit branches,fruit nodes and bolls in early growth stage.However,the rates ofsquaring,flowering,boll setting and opening increased in the late stage.Thus there was nosignificant difference between the two bract type cottons in.yield and percentage of total yieldprior to frost.
