Fig. 2. Daily developmental differences among treatments. Lines terminate on the
day the first embryo hatched in each treatment. Values are means ±
s.e.m.; N=50. Reference lines at stages 32 and 38 facilitate
recognition of the divergence of developmental trajectories among treatments.
At stage 32, embryos in the 18.8 kPa treatment were approximately 1 day in
development ahead of embryos in the 1.8 kPa treatment, whereas at stage 38
this difference had increased to 4 days.
