Two-way ANOVA (p-value)
Salinity 0.001 - - - -
Heat stress 0.001 - - - -
Interaction 0.001 - - - -

Means ± S.E. in the same column with different small or capital letters differ significantly either before or after the heat stress (p < 0.05). The asterisk (*) refers to significant differences between the same groups before and after heat stress (p < 0.05)
