Effects of genotype, seed maturation treatment (‘Maturation’), seed imbibition light (‘Imbibition’) and their interactions on germination proportions, based on logit-linked generalized linear models. Likelihood ratios (LRs) were tested based on χ². Reference levels were white light for maturation, Ler for genotype and white light for imbibition light. The residual d.f. in each imbibition temperature = 117. To aid in interpretation of significant effects, see Tables 2 and 3; Tables S2–S4.
