Data is presented as means of three replicates ± SD and HSD values. F ratio values, * indicates significance at p ≤ 0.05 and ** indicates significance at p ≤ 0.01). Different letters on the table indicate that mean values of treatments are significantly different at p < 0.5 according to Tukey’s multiple comparison.
