P values derived from the ANOVA for effects of nursery fertilization (NF), excision treatments (E), and their interaction (NF×E) on Quercus variabilis seedling morphological attributes at nursery phase.

Seedling RCD, ratio of height to diameter (H/D), root dry mass, stem dry mass, total dry mass, root surface area and the number of first order lateral roots with diameter larger than 1 mm at the taproot junction (FOLR (D>1 mm)) were investigated and analyzed.
