* Means within the same column differ significantly from the control at p ≤ 0.05. ^a,b Means within the same column differ significantly (p ≤ 0.05) according to Newman–Keuls mean comparison (only in the case of significant DxT interaction). ¹ Data represent mean values of seven replications per treatment. SEM = SD divided by the square root of the replication number, n = 7. ² Designations for the treatments as for Table 2.
