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

In order to analyze the effect of salt tolerance improvement by exogenous gene transformation,six transgenic maize crosses with BcWRKY Ⅰ 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,planth eight,dry weight,proline content and so on were analyzed to evaluate the effect of the transformation of Bc-WRKY Ⅰ 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.
