摘要: 【目的】研究棉花黄萎病对海岛棉产量和纤维品质的影响,为防治海岛棉黄萎病提供理论依据。【方法】以海岛棉新海42号为研究对象,对病圃样本中所有该品种棉株按病级分类,进行单株收花、计产及考种。【结果】黄萎病发病程度对海岛棉产量影响表现为,随着发病病级的升高,单株铃数、单铃重、衣分均显著降低;对海岛棉纤维品质的影响表现为0级,上半部平均长度、断裂比强度、马克隆值、纤维整齐度、成熟度、纤维伸长率、短绒率与Ⅳ级病株的相关指标相比,差异显著。【结论】海岛棉(新海42号)发病程度对单株的产量影响较大,且对单株的纤维品质各项指标均有不同程度影响。

Abstract: 【Objective】 To study the effect of verticillium wilt on yield and fiber quality in Island Cotton Xinhai No. 42 in the hope of providing a theoretical basis for the further prevention and control of verticillium wilt in Island Cotton.【Method】With the island cotton Xinhai No.42 as the research object, all samples of cotton stalk in field desease mursery conditon were cut on October 30th and the occurrence grades were classified and the yield tested and analysed.【Result】The effect of the of cotton verticillium wilt on yield showed that the boll number, boll weight, lint decreased with the increase of the grades of cotton verticillium wilt; the effect of the occurrence grades of cotton verticillium wilt on fiber quality showed that the differences between healthy plant and grade IV diseased plants were significant in upper half mean length, HVI strength, micronaire value, maturity, uniformity and short fiber.【Conclusion】The effect of occurrence grades of cotton verticillium wilt on Yield in Xinhai 42 was great, which showed that the disease had different degrees of effect on different indexes such fiber quality of the plant.

Key words: cotton verticillium wilt; occurrence grades; inland cotton; yield; fiber quality
