摘要：利用不同浓度Zn处理菊芋幼苗,研究Zn在菊芋幼苗生长期间,对其幼叶中过氧化物酶(POD)同工酶、株高、叶绿素含量及细胞膜通透性的影响。结果表明:低浓度的Zn(0～5 mg/L)对菊芋幼苗的生长具有促进作用;随着Zn浓度的不断增加,菊芋幼叶中诱导型POD活性增强,增加了2种同工酶的表达;菊芋叶片中叶绿素含量呈下降趋势,细胞膜透性则持续上升。
Helianthus tuberosus seedlings were treated by Zn with different concentrations,the effects of Zn on the peroxidase isoenzymes,plant height,chlorophyll content and membrane permeability in young-leaves were researched.The results showed that low concentration Zn（0-5 mg/L） can stimulate the growth of Helianthus tuberosus seedlings.With the increase of Zn concentration,the activity of induced peroxidase isoenzymes in young-leaves and the expression of two kinds of isoenzymes increased,the chlorophyll content had decline trend,the membrane permeability increased continuously.
