以10个不同基因型棉花品系为试验材料,采用株式图记载棉株各部位蕾铃发生、生长和脱落情况,以探明棉花在夏播短季栽培条件下的棉铃形成时空分布特征。结果表明:在时间分布上,现蕾高峰期为播种后第56天至第80天,开花高峰期为播种...展开更多 以10个不同基因型棉花品系为试验材料,采用株式图记载棉株各部位蕾铃发生、生长和脱落情况,以探明棉花在夏播短季栽培条件下的棉铃形成时空分布特征。结果表明:在时间分布上,现蕾高峰期为播种后第56天至第80天,开花高峰期为播种后第77天至第96天,成铃高峰期为播种后第85天至第101天,各品系生殖器官(蕾、花、铃)数量积累均有显著差异;在空间分布上,P56-3、07...
