Analysis on Salt Tolerance of Transgenic Maize（Zea mays L. ） Crosses with BcWRKY I Gene in Seedling Stage

为了明确外源基因提高玉米耐盐性的效果，以6份转BcWRKYI基因的玉米杂交组合及其对应的6份非转基因对照组合为试材，对其发芽率、耐盐级别、株高、干重、脯氨酸含量等7个指标进行分析。结果表明：耐盐级别、发芽率、干重、叶绿素舍量和相对电导率的变化均达到显著水平，株高的变化达到极显著水平，脯氨酸含量转基因与非转基因组合间差异不显著。In order to analyze the effect of salt tolerance improvement by exogenous gene transformation, six transgenic maize crosses with BcWRKYI gene and six respective non-transgenic control of them were used to identify salt toleranc in seedling stage. Seven indicators such as the germination rate, salt resistance level, plant height,dry weight,proline content and so on were analyzed to evaluate the effect of the transformation of Bc- WRKYI gene on improving the salt resistance. The results indicated that salt resistance level,germination rate, dry weight,chlorophyll content, relative electric conductivity appeared significant differences, plant height appeared extremely significant differences,however,the difference of proline content was not significant.农业部转基因重大专项资助项目0423-2
