摘要
1986～1989年在盆栽条件下,研究了土壤水分对棉籽发育的影响。结果表明:整个花铃期缺水对单铃种子数、棉籽体积、干物质重量以及种子中脂肪和蛋白质的积累均有不良影响。但盛花期缺水对其影响最大;初花期轻度缺水,能适当控制营养生长,减少用水量,有利于棉籽的发育,降低棉籽壳仁比,增加蛋白质积累。干旱对棉籽发育的影响大于对纤维发育的影响。
The effect of soil water on the development of cotton seeds was studiedunder the condition of pot culture in the years of 1986～1989. The results showed thatthe shortage of soil water during the flowering and boll period led to the harmful effecton seed numbers per boll. seed bulk, accumulation of dry matter. seed weight as well asaccumulation of oil and protein contents. The most serious effect was in the case ofshortage of water during the blooming stage. If less water was given in the first bloom-ing period. the vegetative growing could be controlled properly thereby to reduce wateruse. which is favourable for seed development and decreasing the ratio of kernel to bulkof cotten seeds and increasing the protein contents. Droughts can affect the developmentof cotten seeds more serious that that of fibers.
