* Values are means ± SE (n = 10). Mean values in each column with the same letters were not significantly different at p ≤ 0.05. a, b, c, d, e, f, g, h: Different letters next to the mean values in each column indicate significant difference (LSD p ≤ 0.05). * and ** indicate different at p value <0.05, 0.01 probability level respectively, “ns” indicate non-significant.
