From: Functional response of Quercus robur L. to taproot pruning: a 5-year case study
Changes of morphological traits along year, seedling planting density, and taproot pruning status. a Specific leaf area (SLA). b Specific stem length (SSL). c Specific root length (SRL). One-way ANOVA results were obtained for values within an experimental year, then Tukey’s test was performed: a SLA (fourth year F = 1.30, p = 0.280; fifth year F = 0.44, p = 0.720); b SSL (second year F = 0.34, p = 0.792; fourth year F = 4.12, p = 0.009; fifth year F = 0.45, p = 0.716); c SRL (second year F = 1.36, p = 0.265; fourth year F = 1.23, p = 0.304; fifth year F = 0.51, p = 0.674). Treatments were matched as follows: seedling density per container (four or eight) and pruning status (C = control and P = seedlings with pruned taproots). Number of analyzed seedlings; 2012—4C = 24, 4P = 24, 8C = 24, 8P = 16; 2014—4C = 24, 4P = 8, 8C = 32, 8P = 32; 2015—4C = 12, 4P = 8, 8C = 16, 8P = 16
