Results are expressed as means ± standard errors. Different superscript lowercase letters in a column represent statistically significant differences between mean values for each main effect at p < 0.05 obtained by a two-way ANOVA and Tukey’s test. First (Cv. × CP, Cv. × L, CP × L) and second order interactions (Cv. × CP × L) are presented. Significance: ***—p < 0.001, **—p < 0.01, *—p < 0.05. DW—dry weight.
