1.1. 39项实验结果表明，掌纹海参和带海参在胚胎早期发育过程中呼吸作用持续增强。这种增加在原肠胚形成前较慢，在原肠胚形成末期和神经节形成期间更为迅速。致命杂交组合triton palmatus♀×Salamandra atra♂或triton taeniatus♀×Salamandra atra♂在囊胚晚期的关键阶段表现出较低的耗氧率。在后期，呼吸频率仍然很低，发育不超过早期原肠期。基于本研究结果和对黑腹果蝇3种致死性突变体的观察。讨论了致死率代谢的一般方面：Ltr、lgl和lme。
1.1. The results of 39 experiments performed onTriton palmatusandtaeniatusindicate that there is a continuous rise of respiration in the early embryonic development. Such an incrase is slower until gastrulation, and more rapid at the end of gastrulation and during neurulation.2.2. The lethal hybrids of the combinationTriton palmatus♀ ×Salamandra atra♂ orTriton taeniatus♀ ×Salamandra atra♂ show a lower rate of oxygen consumption than the controls in the critical phase i.e. in the advanced blastula stage. In later stages the respiratory rate remains low and the development does not exceed the early gastrula stage.3.3. Based on the results of the present study and those observed on the three lethal mutants inDrosophila melanogasteri.e.ltr,lgl, andlme, the general aspects in the metabolism of lethality are discussed.
