| 摘 要： | 有机锡对海洋微藻的毒性效应研究主要侧重于对各种微藻生长半抑制浓度的比较(赵丽英等,1990)和富集能力的测定(Beaumant and Newmen,1986),以及对微藻固碳能力(Callow and Evans,1981)和色素含量的影响(高尚徳等,1994),而对海洋徽藻的细胞器损伤方面的研究相对较少。本文以半抑制浓度的TPTC处理等鞭金藻细胞,观察其超微结构的变化,为研究有机锡对海洋微藻的毒性效应提供了细胞学方面的基础资料。

| Abstract: | Electron Transmission examination of the ultrastructure of Isochrysis galbana cells exposed to TPTC at half effective concentration (EC50) showed that the mitochondria was swollen,and that ridge was damaged. In the chloroplast, the thylakoids were piled up and the reticulate structure of the photosynthetic lamellae was damaged. The nuclear and vacuole membrane was partially damaged, the cytoplasm was vaculated. Cell membrane was folded and partially damaged. |
