Mean and SD are the arithmetic mean and standard deviation, respectively, and n is sample number across the nine treatments with three replicates.
* Different lower-case letters indicate significant difference (P < 0·05) based on one-way ANOVA and least significant difference post-hoc test among seven groups.
