In Mo17, the POD activity of the 0.25% chitosan
treatment was higher than that of the control but
higher concentrations of chitosan did not significantly
affect POD activity (Table 5). There was no significant
effect of chitosan treatment on the CAT activity
of this variety either.
In HuangC, seed priming with 0.50% chitosan
had no significant effect on POD activity, but significantly
increased CAT activity in comparison with
the control (Table 5). Between the three chitosan
treatments there was no significant difference in CAT
activity
