摘  要:
通过对棉花不同种质材料的棉铃在不同发育时期重量和长宽比的研究。结果表明,不同发育阶段的棉铃在重量和长宽比存在较大的差异;陆地棉和海岛棉的棉铃重量第5天和第10天变化趋势基本相同,但长宽比存在差异;两者的关系是长宽比越大,其铃重越轻;不同类型品种棉铃的长宽比是海岛棉>圆锥形铃陆地棉>卵圆形铃陆地棉>圆形铃陆地棉,而重量恰好相反,为圆形铃陆地棉>卵圆形铃陆地棉>圆锥形铃陆地棉>海岛棉;杂交棉相对于其亲本变化不明显。由此可见,棉花品种类型不同,棉铃形状的差异都是影响棉铃发育的重要因素。

摘  要:
The paper studies the boll weight and length- width ratio at different development stages of different cotton varieties. The results show that,in every period of boll,weight and length- width ratio have great differences,in the boll weight,the change trend of upland cotton and sea island is basically same,but the length- width ratio of island cotton and upland cotton is difference. the ratio of length- width is larger,the boll weight is lighter,length- width ratio is the sea island cotton > upland cotton( conical) > upland cotton( arbitrary circular) > upland cotton( circular),and the weight is contrary,upland cotton( circular) > upland cotton( out of round) > upland cotton( conical),sea island cotton,hybrid cotton relative to its parent does not change obviously. Thus,cotton varieties of different types,different shapes of cotton boll are an important factor affecting the development of cotton bolls.
