Table 4.
Two-way ANOVA for the level of photoinhibition after combined drying and light exposure in Lobaria pulmonaria and Platismatia glauca from different habitats, and exposed to four levels of desiccation (see Fig. 2)

Photoinhibition was expressed as Fv/Fm as a percentage of the start values. Factors were RH drying (0%, 35%, 55% and 75% RH) and habitat types specified in Table 3 for each species.
