中文摘要:
      通过室内盆栽试验,在苗期连续干旱胁迫下,测定了与抗旱性有关的7项指标,运用五级评分法对20份野生鸭茅种质资源(Dactylis glomerataL.)抗旱性进行了综合评价,根据综合评价值的大小,确定了20份野生鸭茅的抗旱性强弱顺序为:ZXY03P-173>ZXY03P-191>ZXY04P-4>ZXY04P-226>ZXY03P-22>ZXY04P-201>ZXY03P-122>ZXY03P-227>ZXY04P-207>ZXY04P-75>ZXY04P-136>ZXY04P-57>ZXY04P-101>ZXY04P-189>ZXY04P-148>ZXY04P-239>ZXY04P-22>ZXY03P-69>ZXY04P-155>ZXY04P-89。
英文摘要:
      Eleven indices of drought tolerance at seedling stage were examined in greenhouse under drought stress,and the drought tolerance of 20 wild Dactylis glomerata L.germplasm was comprehensively evaluated with five level grade methods.According to the result of the evaluation,the relative drought resistance of 20 wild Dactylis glomerata L.germplasm is:ZXY03P-173>ZXY03P-191>ZXY04P-4>ZXY04P-226>ZXY03P-22>ZXY04P-201>ZXY03P-122>ZXY03P-227>ZXY04P-207>ZXY04P-75>ZXY04P-136>ZXY04P-57>ZXY04P-101>ZXY04P-189>ZXY04P-148>ZXY04P-239>ZXY04P-22>ZXY03P-69>ZXY04P-155>ZXY04P-89.
