摘　　要：研究在盐渍环境(0.8%的NaCl)下,不同浓度多效唑浸种对玉米幼苗生长的影响.结果表明,与对照组(蒸馏水浸泡)相比,经不同浓度多效唑浸种后,玉米幼苗株高矮化,根冠比增大;叶片中叶绿素含量增多,丙二醛含量和过氧化物酶活性明显降低.其中经200 mg/L的多效唑浸种后的玉米,在盐胁迫环境下对植株幼苗的影响最为显著.The effects of seed soaking in different concentration of PPsolution on the growth of corn seedlings under salt stress(0.8%NaCl)were studied.The results showed that under salt stress,in comparison with the control groups(soaking of seed in water),the plant height of the soaked seeds were lower,but the rate of root length/plant height were higher;in addition,the chlorophyll content were increased,but MDA contents and POD activity were obviously decreased.The most significant effects were found with the seed soaking in 200 mg/L PP_(333)under the salt stress.
