Data presented as mean ± SD (n = 5). For each year, values for the same parameter evaluated (within the same column) followed by different lowercase letters are significantly different at p < 0.05, according to Tukey’s test. Uppercase letters indicate differences between the harvest years (p < 0.0001). DW, dry weight.
