【摘要】温度、pH、酶抑制剂H2O2和KCN均对转SOD基因烟草及其子代(S1和F1)的SOD活性有影响。在这些不利条件下,转基因SOD高表达烟草品系的SOD耐性明显优于对照品系,且其S1、F1能很好地保持亲本的这种优势。更多还原

【Abstract】 The conditions such as temperature,pH,enzymatic inhibitor H₂O₂ and KCN affected SOD activities of the leaves in near isogenic tobacco lines（including transgenic lines with SOD gene in chloroplast and non-transgenic line）and their S1 progenies or F1 hybrids. Under these unsuitable condition,transgenic tobacco lines with overexpressed SOD gene showed obvious advantages in SOD tolerance over that of non-transgenic line,and these advantages could be passed down to their S1 progenies or F1 hybrids.更多还原
