Different letters indicate significant differences as shown by Tukey’s HSD test at p < 0.05. Values with different letters “a–e” (in the rows) indicate significant difference for different biomass at the same storage options, and “u–z” (in the columns) indicate significant difference for the same biomass in different storage options; both at p ≤ 0.05 in Tukey’s HSD test.
