摘要/Abstract

摘要： 1987—1990年在盆栽条件下研究了花铃期土壤水分对棉花种子发育及活力的影响。试验结果表明,棉花花铃期缺水时,单铃的不孕子数增加,种子数减少,百粒种子重(子指)和种仁率降低。初花期缺水主要影响种子的形成,进入盛花期后缺水主要影响种子的干物质积累和饱满度。缺水条件下形成的棉子,种仁中蛋白质含量较高,脂肪含量较低。从

Abstract: The effects of soil water during the flowering and fruiting stages on the develop-ment and vigor of cottonseeds were investigated in pot trials in 1987--1990. Theresults showed that, under drought condition during these stages, the number ofunfertilized ovules per boll increased, while the number of
