本试验用不同浓度的水杨酸对玉米幼苗进行处理,研究水杨酸对玉米幼苗生长和发育的影响.结果表明,一定浓度的水杨酸处理对玉米幼苗的鲜莺、苗高、叶绿素含量、SOD、POD的活性以及MDA、相对外渗率都有明显影响,在水杨酸浓度为1.5mg/L时效果较好,鲜重和苗高分别比对照增加了45.6%和28.2%,叶绿素含量、SOD和POD的活性也分别比对照组增加了147.7%、53.8%和25.3%;而MDA和相对外渗率分别比对照下降9.6%和17.3%.

The corn seedlings were treated by different concentrations of salicylic acid in the experiment to study how its growth and development affected.The results showed that fresh weight,seedlings height,chlorophyll content,activities of SOD and POD,MDA and electrolyte leakage rate were significantly affected by the treatment.The growth and development of seedlings were promoted after 1.5 mg/L treatment.The fresh weight and seedlings height were increased by 45.6%and 28.2%respectively.Also,Chlorophyll content,activities of SOD and POD were increased by 147.7%,53.8% and 25.3% respectively.The MDA and electrolyte leakage rate were decreased by 9.6% and 17.3% respectively.
