Values are presented as the mean ± SD, and data with different lowercase letters indicate significant differences at the 0.05 level.
WT, wetting time; SR, suspension rate; Ki (column m) = the sum of the number in column m corresponding to the ‘i ‘index; R, range; R (column m) = the difference between the maximum and the minimum in each average of column m K1, K2, etc.
