摘　　要：在PEG溶液模拟干旱条件下,研究了不同玉米品种(2个转基因品系和各自受体对照)发芽率、伤害率、芽根比、叶片含水量、叶片SOD活性、POD活性和MDA含量,并对其在种子盒、花盆和田间的耐旱性进行了比较。结果表明,萌发期与苗期抗旱性表现基本一致,2个转基因品系(T09100-3和H5T37)分别比各自受体(综31和178)耐旱性高。Under the drought conditions simulated by PEG solution,we researched the germination rate,damage rate,shoot-root ratio,leaf moisture content,leaf SOD activity,POD activity and MDA content of different maize varieties.And their drought tolerances in seed box,pot and field were compared.Results showed that the drought resistances at germination stage and seedling stage were basically the same.The two transgenic strains(T09100-3 and H5T37)showed greater drought tolerance than their own receptors(Zong 31 and 178).
