Summary of the results of statistical analyses (GLM, p values of nested ANOVA)
| Effect | df | F V/F M | Total phenolics | Chlorophylls a + b | V + A + Z | Other primary carotenoids | Deepoxidation state |
|---|---|---|---|---|---|---|---|
| UV treatment | 1 | <0.0001 | 0.0012 | 0.9884 | 0.0813 | 0.2829 | 0.0473 |
| Strain | 2 | 0.0001 | 0.0037 | 0.0816 | 0.0058 | 0.0129 | 0.0022 |
| Petri dish (strain) | 6 | 0.0319 | 0.5595 | 0.15 | 0.3896 | 0.2545 | 0.3961 |
| Strain × treatment | 2 | <0.0001 | 0.0404 | 0.9163 | 0.7539 | 0.3247 | 0.0776 |
‘UV treatment’ and ‘strain’ were considered as fixed effects, ‘Petri dish’ was considered as a random effect
Petri dish (strain) Petri dish nested in strain, F V /F M PS II efficiency, V + A + Z xanthophyll cycle pigments, Deepoxidation state the ratio (A + Z)/(V + A + Z)
