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。
The conditions such as temperature,pH,enzymatic inhibitor H2O2 and KCN affected SOD activities of the leaves in near isogenic tobacco lines（including transgenlc lines with SOD gene in chloroplast and nontransgenic 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.
