The values are Mean ± Standard error of mean (n = 3). Capital letter superscript compares between means in column, and means with similar capital letters represent no significant difference, whereas means with different capital letters are significantly different at p < 0.05. Small letter superscript compares between means in row, and means with similar small letters show no significant difference, whereas means with different small letters show significant difference at p < 0.05. ‘ZD’ is zero diameters
