Table 3.
Comparison models testing the difference of the effect of time (simple and quadratic effect, ‘Time’ and ‘Time2’, respectively) on nectar and flower traits between the climate chamber and outdoor treatment (‘group’). Only interaction terms are presented here from the model full results. Statistically significant (P < 0.05) results are presented in bold.
