烂铃是影响棉花产量和纤维品质的重要因素。为了明确烂铃对棉花产量因子和纤维品质的影响程度,以11个常规种和11个杂交种为试验材料,分别测定了烂铃与正常铃的产量因子和纤维品质性状。结果表明:与正常铃相比,烂铃的铃重、子指和衣分3个产量因子均出现了极显著差异,其中,铃重和子指分别降低了19.22%和15.33%,衣分提高了1.31%;烂铃纤维的马克隆值、断裂比强度、伸长率、上半部平均长度和整齐度也出现了极显著差异,分别下降了20.37%、10.18%、9.26%、4.21%和3.27%。并分析了烂铃对杂交种与常规种产量因子和纤维品质的影响,结果显示,除对衣分的影响差异达到了显著水平外,对铃重、子指以及纤维品质性状的影响差异均不显著。
Suffering bolls is an important factor affecting cotton yield and fiber quality. In order to clarify the influence degree of rotten bolls on cotton yield and fiber quality, 11 conventional and 11 hybrids were used as materials to determine the yield factors and fiber quality traits of rotten and normal bolls. The results showed that there were significant differences in the three yield factors of boll weight, index finger and lint of the rotten bolls, in which boll weight and index finger decreased by 19.22% and 15.33%, respectively, 1.31% respectively. The micronaire value, breaking strength, elongation, average length and uniformity of the upper part also appeared extremely significant difference, which decreased by 20.37%, 10.18%, 9.26%, 4.21% and 3.27% %. The effects of rotting bolls on the yield factors and fiber quality of hybrids and conventional varieties were analyzed. The results showed that the differences of the effects on the boll weight, the index finger and the fiber quality traits were not significant Significant.
