Oxygen permeability of the chorion in relation to diapause termination inBombyx eggs

Experientia Aims and scope Submit manuscript

Summary

Oxygen permeability of the chorion of the silkworm,Bombyx mori, was measured in relation to embryonic diapause. It did not change appreciably when the eggs were freed from diapause by being kept under long chilling. This finding suggests that the increase in oxygen permeability of the chorion is not a pre-requisite for the termination of the diapause and resynthesis of glycogen from 2 polyols.
