The data are the means ± SDs of three replications. Use different letters to indicate significant differences in average values between the treatments within each individual time (P ≤ 0.05) based on Duncan’s multiple range test.

Control, 75–80% of the MWHC; T1, 55–60% of the MWHC; T2, 40–45% of the MWHC; T3, 20–25% of the MWHC.
