摘要:
为了研究细胞渗透调节物质与早熟禾抗旱机理的关系，在现有的试验条件下，以黑龙江硬质早熟禾作为供试材料，采用连续干旱处理的方法，与国外引进品种印第安酋长和统治者进行比较，研究3个早熟禾细胞内渗透调节物质与抗旱性相适应的关系。结果表明：3个草种体内的可溶性糖及脯氨酸含量均升高，复水后降低；可溶性蛋白呈下降趋势，复水后呈上升趋势。三者表现出的积累速度和恢复能力为：硬质早熟禾>印第安酋长>统治者。
Abstract:
In order to study the relationship between cell osmotic regulator and bluegrass drought resistance mechanism，taking two introduced varieties of Poa sphondylodes L.from aboard(Reubens and Ruler)and one wild growth Poa sphondylodes T.in Heilongjiang as test materials.The intracellular osmolyte of soluble sugars,free proline and soluble protein of Poa sphondylodes L.and the relationaship were researched by continuous drought stress.The results showed that intracellular osmolyte of soluble sugars and free proline of three varieties all increased under drought stress,but decreased when rewatering.Soluble protein decreased under drought stress,while increased after rewateing.The accumulation speed and recovery ability was that Local bluegrass>Reubens>Ruler.
