摘　　要：本实验研究0.05%MES对野生型拟南芥生长的影响。结果表明,含有MES的培养基pH变化较小,其培养10d的拟南芥幼苗干重、鲜重、叶绿素含量和含水量均高于对照组,而叶片PAL和POD活性却低于对照组,说明MES通过影响培养基的pH变化促进拟南芥生长。The effects of MES on the growth ofArabidopsis thaliana were analyzed in this study. The Arabidopsis seedlings were cultured on the medium with and without 0.05% MES, respectively. The results showed that the levels of dry weight, fresh weight, chlorophyll content and water content of Arabidopsis seedlings grown on the medium with 0.05% MES were higher than those without MES. Moreover, the activities of PAL and POD of Arabidopsis seedlings grown on the medium with 0.05% MES was lower than those without MES. These results indicated that MES could promote the growth ofArabidopsis thaliana through keeping the pH value of medium in stabilization.
