Table 3.
Effect size (%) on the physiological and biochemical parameters relative to the control condition in each of the experimental phases (Phase1: nitrogen enrichment; Phase 2: nitrogen enrichment + thermal stress; Phase 3: recovery). (↑) indicates increased levels, (↓) indicates decreased levels, and (–) indicates non-significant changes.
