Results are means of 3 replicates for each treatment; the value is the standard error of the mean. Values below the detectable levels are indicated in the graphs as ND (not detected); NA (not applicable)
ND not detectable, NA not applicable
Different superscripts in the same column are significantly different (P < 0.05) based on the ANOVA
