Differences in variables among treatments were tested using factorial analysis of variance (ANOVA). Values are means ± standard deviation. In each row, means followed by different letters are significantly different (P < 0.05). SE-M3 non-osmotic medium (control) and SE-M9 osmotic medium. Software ImageJ.
