摘　　要：研究了不同浓度三丁基氧化锡(Tributyltin oxide,TBTO)对坛紫菜(Porphyra haitanensis)离体细胞生长的影响。结果表明:低浓度(<0.25 nmol/L)的TBTO,在培养前3天,可促进坛紫菜体细胞的分裂,但随着时间的延长则会转变为抑制作用,而高浓度(>1 nmol/L)的TBTO则只有抑制作用。TBTO对坛紫菜细胞72 h的半数致死浓度约为1.9 nmol/L。The effects of different concentrations of TBTO on the growth and development of seperated cells of Porphyra haitanensis were evaluated.The results showed that low concentrations of TBTO(<0.25 nmol/L)could promote somatic cells division for Porphyra haitanensis in the first 3 days after treating.However,the promoting effect would be converted into inhibition for the cell growth with time prolonged.High concentions of TBTO(>1 nmol/L)only possess an inhibition effect on cell growth.The 72 h LC50(half lethal concentration) of TBTO to Porphyra haitanensis cells is about 1.9 nmol/L.
