摘　　要：通过对水稻旱作条件下渗透调节物质和激素含量的试验研究 ,结果表明 :叶片和根系质膜相对透性 > > ,差异显著 ;脯氨酸含量 > > ,差异极显著 ;可溶性糖含量 、 均高于 ;生长素、赤霉素和细胞分裂素 、 与 之间差异不显著 ,脱落酸 > > ,差异极显著。提出运用产量、脯氨酸含量、质膜相对透性、单株有效分蘖数。It indicated that the research result on the permeability regulation matter and hormone content of dry cultivation rice was as following: the relative permeability of plasma membrane in root and leaf wasⅠ>Ⅱ>Ⅲ, and it has significant difference; the order of free proline content wasⅡ>Ⅲ>Ⅰ, and it has very significant difference. The soluble suger content ofⅡand Ⅲ was higher than that ofⅠ. There was no significant difference betweenⅠ,Ⅱand Ⅲ of IAA,GA3 and CTK content, but that of ABA has significant difference. The synthetical indicators with the yield, the free proline content, the membrane relative permeance rate, the effective tillers per plant and the seed set rate were chosen for the selection of drought endurance cultivars.\;
