Effect of low temperature stress on proline, malondialdehyde contents and electric conductivity of maize seedling
Jing Hou · Dongbei Nongye Daxue xuebao · 2008
Changes of Pro, MDA contents and relative electric conductivity in Dongnong250, Simi21 and Tunyu88 seedling leaves were studied under the condition of low temperature stress. The results showed that under different low temperature stresses, MDA content and relative electric conductivity of different varieties were all increased, the incremental range of Tunyu88 was significantly higher than that of Dongnong250 and Simi21, Pro content was also increased, but the incremental range of Dongnong250 was significantly higher than that of Simi21 and Tunyu88. Among the three tested cultivars, the order of cold damage resistance from higher to lower was Dongnong250, Simi21 and Tunyu88.
