∗, , and indicate significant differences at the 0.05, 0.01, and 0.001 levels of probability, respectively. In each column and for each factor or interaction, different letters indicate significant differences according to Duncan’s multiple range test at the 95% confidence level. TPI: total phenolic index and YAN: yeast-assimilable nitrogen.
