摘　　要：实验结果表明,通过导入拟南芥AtDREB1A基因优化了银新杨对干旱、高盐和低温的耐受性。在相同的干旱、高盐或低温处理下转基因植株的抗坏血酸过氧化物酶(ascorbate peroxidase,APX)和过氧化氢酶(catalase,CAT)活性,均高于对照植株,且差异显著。The results of experiment showed that by introducing gene AtDREB1A, the tolerance of Yinxin poplar to dehydration, high - salt and low temperature were optimized. Transgenic plants had higher ascorbate peroxidase and catalase activity than control plants in the same dehydration, high salt or low temperature conditions, and the difference was significant.
