Results of generalized mixed-effects linear models performed to assess the effect of shade (open vs. shaded), watering (watered vs. non-watered) and its interaction on the onset, end, duration and relative production of R. nudiflora chasmogamous flowers (Flowers), chamosgamous fruit and cleistogamous fruit (CH Fruit, CL Fruit)

The variables ‘onset’ and ‘end’ were fitted to gamma models, and the rest to Poisson models. Statistically significant differences are highlighted in bold.
