运城盐湖植物有机渗调剂的比较研究

Comparative Study of Organic Osmotic Substances in Plants of Yuncheng Saltlake

本文测定了生长在运城盐湖的 1 0种植物体内的有机渗透调节剂的含量 ,结果表明 ,盐生植物地上部的总有机物及氨基酸含量均低于非盐生植物 ;除独行菜外 ,单子叶植物地上部的可溶性糖含量高于双子叶植物 .根据各种植物积累可溶性糖和氨基酸的相对量 ,对植物进行了分类 .

The content of organic solutes in plants of Yuncheng saltlake was determined. The results showed that a lower content of total organic solutes and amino acids in halophytes than in non halophytes and a higher content of soluble sugars in monocotyledons than in dicotylendons exlept Lepidium apetalum willd. According to their capacity to accumulate soluble sugars and amino acids, plants can be derided into three main groups.
