Table 1 Results of ANOVAs for the morphological and biochemical/physiological traits measured in three harvesting years (* for the SLA, only 2 years, 2014 and 2015, were considered) using the harvesting year, root pruning status, and planting density as the factors. F and p values are included, and nonsignificant interactions are excluded

Trait | Value | Year (df = 2) | Root pruning (df = 1) | Seedling density (df = 1) | Year × root pruning (df = 2) | Year × seedling density (df = 2) | Root pruning × seedling density (df = 1) | Year × root pruning × seedling density (df = 2) |
