摘 要:作者用含微量的Cd2+,Hg2+,Cr6+和敌枯双的四种药物,处理布氏轮藻(C.baruni)和普生轮藻(C.vulgarisVais.exL.)后,经一年多的实验与观察,发现上述四种约物对轮藻藏卵器的大小和着生位置都有影响,以藏卵器大小变化尤为显著,进一步研究证明,这些变化是不稳定的.因此,轮藻的分类应考虑水域环境的影响.In was repored the oogone length of C.braunii and C.vulagaris had changed greatly compared with the contrast group after chara braunii and chara vulgaris Vail exl were treated by trace elements:Cd^2+,Hg^2+,Cr^6+ and pesticide∶Dikushuang in the conditon of simulated nature.It was fully proved that the oogone length of same species of C.would chang in the different ecological environment.Therefore,it isn’t proper to differentiate the species,variety,subspecies and variant only according to the length of oogone.
