摘　　要：用不同浓度的乙草胺分别对中华大蟾蜍 4个不同发育时期的早期胚胎作用 5小时 ,结果发现 ,不同浓度的乙草胺可以导致中华大蟾蜍早期胚胎不同程度的发育成原肠外突和畸胎。不同发育时期的中华大蟾蜍早期胚胎对乙草胺的敏感程度和耐受程度都有所不同 ,其中 ,原肠胚期的胚胎对乙草胺最为敏感。实验表明乙草胺对中华大蟾蜍早期胚胎发育具有明显的致畸致死效应。Early embryos at four different development stages of Bufo bufo gargarizans were treated with acetochlor of different concentration for 5 hours.It was found that acetochlor can make embryos exogastrulation or death,yet embryos at different stages show different sensitivity to acetochlor.Among the four stages,gastula period is the most sensitive stage.Results demonstrate that acetochlor possess distinct deformative and deadly effect on development of early embryos of Bufo bufo gargarizan.
