Fig 6. Bar plot of the percent composition of embryonic developmental stages at week 1 under the different conditions.

L⁺ T⁺ = high light–high temperature, L⁺ T^- = high light–low temperature, L^- T⁺ = low light–high temperature, L^- T^- = low light–low temperature. I = embryos with 4 primary rhizoids, II = embryos with 8 rhizoids, III = embryos with short apical hair/s, IV =: mbryos with long apical hair/s.
