Percentage data were arcsine-square root transformed to normalize
variance before ANOVA analysis. All data were subjected
to analysis of variance using Statistica 6.0 software.
Mean values
of treatments were compared by using Fisher’s protected LSD test
and judged at P
≤
0.05 level. In all cases, experiments were repeated
twice and average was shown. Data in the graphs are untransformed
