摘　　要：报道了在栽培条件下，微量的Ｃｄ２ ＋ 、Ｈｇ２ ＋ 、Ｃｒ６ ＋ 和故枯霜对普生轮藻（ Ｃｈａｒａ Ｖｕｌｇａｌｉｓ Ｖａｉｌｌ．ｅｒｌ．） 产生不同程度的影响，使其托叶长度发生较大的生态变异。试验结果表明：药物影响的大小和药物剂量及作用时间有密切关系，并指出以托叶长度作为轮藻分类的依据有特进一步研究。The paper reports on the different efects of trace drugs(Cd,Hg,Cr and“Dikushuang”)on the growth of the Stipulode of Chara Vulgaris .exl .under the cultivated conditions and the four drugs cause its leaf to produce ecological variation.The essay shows that this kind of effects has a close relationship with the dosage and the acting time of the four drugs.Hence,whether to use the length of the Stipulode as the basis of Chara classification or not is worth of our further discussion.
