Table 5 Mean values and standard deviation of the variables of growth [length (cm) and biomass (mg)] of the seedlings of Cistus ladanifer. The seeds were exposed to a heat shock of 100ºC for 10 minutes. The seeds were left to germinate under different treatments Con: control; ↑Lit: high load of litter; ↓Lit: low load of litter; ↑Ash: high load of ash; ↓Ash: low load of ash. Half of the seedlings were removed after 2 months and the growth variables related to length and biomass were measured. The same procedure was repeated after 4 months with the remaining seedlings. Different letters show the significant differences in the growth of the seedlings (P ≤0.05) among the treatments according to the pairwise comparison using Bonferroni’s correction and the one-way ANOVA if the data were normally distributed, or the non-parametric Kruskal-Wallis test if they were not
