P-values obtained using mixed models for plant growth traits. Significant (P < 0.05) factors and interactions are high-lighted in bold. RGRplant (relative growth rate of the whole plant); DWplant (plant dry weight); TLA (total plant leaf area); R:S (root to shoot ratio); TLA:TRL (total leaf area to total root length ratio).
