Changes in PAL activity are shown in Fig. 2D.
SB treatment induced an increase
in PAL activity reaching the maximum level at 12 h, as compared to the controls.
In
particular, the activity was increased by 1.4- and 2.3-fold as compared to wounded
and unwounded controls, respectively.
An increase in PAL activity was also observed
with time in tissues treated with SC, with the peak at 48 h corresponding to a 1.4-
and 1.9-fold increase, compared to wounded and unwounded controls, respectively
