Changes in A) trypsin and B) chymotrypsin inhibitory activities. Changes in A) trypsin and B) chymotrypsin inhibitor activities in tomato leaves harvested at different time points after the following treatments: Control, A. solani inoculation, 0.2% sodium alginate pretreatment, 0.2% sodium alginate pretreatment followed by A. solani infection; 0.4% sodium alginate pretreatment, 0.4% sodium alginate pretreatment followed by A. solani infection; 0.6% sodium alginate pretreatment, 0.6% sodium alginate pretreatment followed by A. solani infection The values represent the mean ± standard error of the mean (n = 3). The asterisks (*, **, ***) indicate that the mean values are significantly different from those of the control at the same time point; ***P < 0.001, **P < 0.01, and *P < 0.05, ns: not significant based on Student’s t-test.
