摘    要:在不同水分和肥料条件下,小麦灌浆期用P-V曲线测定渗透调节能力,结果表明,品种的抗旱性与渗透调节能力呈正相关,渗透调节能力可作为评价小麦品种抗旱性的一个指标;施肥可明显增强冬小麦的渗透调节能力;可溶性糖、氨基酸是主要的渗透调节物质.

关 键 词:冬小麦  灌浆期  渗透调节能力

Abstract:The osmotic adjusting ability and chemical composition of two winter wheat varieties are studied using P-V curve method under different water and fertility conditions at filling stage.The results indicafe that drought-resistance of variety has a positive correlation with osmotic adjustmen ability,the greater osmotic adjustmen ability, the stronger drought-resistance.Osmotic ability can be used as an indicator to evalute the drought-resistance of variety.Manuring can considerably improve the osmotic ability of winter wheat.Soluble carbohydrate and amino acid are major osmotic adjustmen substance.At last,the value and application of this method are discussed in variety breeding for drought-resislance and dryland farming cultivation.
Keywords:Winter wheat  Filling stage  Osmotic adjustmen ability
