Table 2.
GLM results for germination tests of Rhododendron taxa: (A) Maximum germination success after 10 weeks; Germination data were rank transformed prior to analysis. (B) Cumulative germination success expressed by repeated measures ANOVA with factor time. The mixed model was performed with populations as random factor nested within taxon and three replicates each per temperature level (n = 270). P GG adj = P values for Greenhouse–Geisser adjustment.
