摘　　要：采用盆栽法,在干旱胁迫下,测定转基因草坪草与对照株在不同水分胁迫下的根系活力、脯胺酸含量、叶绿素含量和SOD酶活性等抗旱生理指标。以期综合评价该转基因草坪草的抗旱性能和所选指标作为筛选抗旱性指标的可行性。结果表明,转基因草坪草在抗旱性能上普遍优于对照株。同时,SOD酶活性和脯胺酸含量可以作为转基因草坪草抗旱性鉴定指标;根系活力和叶绿素含量为参考指标。The pot experiment was conducted to study on Root system activity,Pro content,chlorophyll content, SOD activity to evaluate comprehensively the drought resistance of transgenosis NAS gene turf grass in different stress and feasibility of these indexes.The result showed the transgenosis turf grass was obviously better than the compared one. SOD activity and Pro content could be regarded as screening index.Root system activity and chlorophyll content were reference indexes.
