摘　　要：以3个饲料型刺槐无性系为研究对象,对干旱胁迫下保护酶类的活性差异进行了研究。结果表明,饲料型刺槐无性系在干旱胁迫下调动各种保护酶来清除体内的活性氧,以保护细胞膜不受活性氧的攻击,但不同的无性系对干旱胁迫有着不同的响应。3个无性系中韩国四倍体主要调动POD酶、匈牙利多倍体主要调动SOD、CAT酶、长叶刺槐主要调动POD、CAT酶。MDA的含量随着干旱胁迫的加剧逐渐增加达到最大值,然后出现下降。The plastic shed test in 2006 with 3 clones of feeding Robinia pseudoacacia shows the feeding Robinia pseudoacacia clones can transfer all kinds of protective enzymes to clear alive oxygen for protecting cell membrane from attacking by alive oxygen. Different clones have different response to the condition of drought stress, Among 3 clones Korea tetraploid mainly transfers POD enzyme, Hungary polyploid mainly transfers SOD enzyme and CAT enzyme and long leaf Robinia pseudoacacia mainly transfers POD enzyme . With strengthening of drought stress, MDA content gradually increases and reaches to maximum, then decreases.
