摘要: 为了探讨视黄酸对蚯蚓再生的影响,用视黄酸处理了从不同部位剪切的蚯蚓体段,观察其存活率、重量和再生长度的变化。结果表明,有头无尾的体段存活率受视黄酸影响较小,而无头有尾的处理受视黄酸影响较大;视黄酸处理后30d,各处理再生长度和存活率均小于对照;视黄酸对蚯蚓再生有明显影响,能延迟和干扰再生,影响头部的形成。视黄酸影响蚯蚓再生的作用方式可能是通过干扰前后体轴的形成,从而影响蚯蚓再生图式形成。

Abstract: To prrobeinto the effects of exogenous retinoic acid (RA) on the regeneration of invertebrate,this paper measured the survival rate,biomass,and regenerated length of E.fetida segments amputated from its different position and treated with RA.The results showed that RA had little effect on the survival rate of anterior segments,but a higher effect on that of posterior segments.After treated with RA for 30 days,the regenerated length was shorter than the control.Exogenous RA disrupted and delayed the regeneration of earthworm and the formation of its head,but not the posterior regeneration.It was suggested that the regional specification during regeneration was distro-proximal,and retinoic acid played an important role in pattern formation during regeneration.
