花铃期土壤幹旱影响棉仁油分、蛋白质形成的生理机理
Effects of soil drought during the flowering and boll formation on quality formation of oil and protein in cottonseed kernel
棉花是集“纤维、油脂、蛋白质”为一体的重要的经济作物，关于幹旱胁迫影响棉花纤维发育的研究较多，而其对棉籽产量和品质形成的报道较少。本研究以德夏棉1号和豫早棉9110为材料，进行花铃期土壤水分管理[土壤相对含水量SRWC:75%±5%（适宜含水量，CK);60%±5%，45%±5%]盆栽试验，研究幹旱对棉籽品质形成的影响。结果表明：SRWC60%±5%对棉仁不饱和脂肪酸(UFA)含量的影响较小，SRWC45%±5%显著降低了UFA含量及脂肪酸不饱和…查看全部>>
Cotton is an important cash crop, producing fiber, oil and protein. There are many studies to analyze the effect of drought stress on cotton fiber development, but few reports on its effects on cotton seed yield and quality formation. In this study, Dexiamian 1 and Yuzaomian 9110 were selected as experimental materials to perform the soil moisture experiment with three settings of soil relative water content (SRWC), including 75%±5% (suitable moisture conten…查看全部>>
