摘　　要：为探究近年来盘锦红海滩翅碱蓬大面积退化的原因,通过水培试验在不同Zn^2+、Cu^2+浓度下测定了翅碱蓬含水率、花青素和叶绿素含量。结果表明,锌和铜作为植物必需的营养元素,低浓度Zn^2+和Cu^2+作用于植物时,对翅碱蓬生长和花青素、叶绿素的合成产生促进作用。当Zn^2+和Cu^2+浓度过高时,翅碱蓬的生长发育就会受到抑制。In order to explore the causes of the death of Suaeda heteroptera in Panjin Red Beach wetlands in recent years,this experiment measured the water content,anthocyanin and chlorophyll content of S.heteroptera by hydroponics at different concentrations of Zn^2+and Cu^2+.The results showed that zinc and copper are essential nutrients for plants.When low concentrations of Zn^2+and Cu^2+acted on plants,they promoted the growth of plants and the synthesis of anthocyanins and chlorophyll.When the concentration of Zn^2+and Cu^2+were too high,the growth and development of S.heteroptera would be inhibited.
