Table 5.

The mean total phenol content and activities of polyphenol oxidase (PPO) and peroxidase (POD) enzymes in sunflower roots in response to colonization with R. irregularis and/or infection with R. solani (28 days after inoculation with R. solani).

Treatment *	Total Phenol Content (mg g⁻¹ Fresh Weight)	PPO (U mL⁻¹ min⁻¹)	POD (U mL⁻¹ min⁻¹)
C	1.813 ± 0.095 ^d	0.213 ± 0.033 ^d	0.153 ± 0.086 ^c
M	2.129 ± 0.046 ^c	0.334 ± 0.045 ^c	0.210 ± 0.061 ^b
P	2.499 ± 0.064 ^b	0.455 ± 0.015 ^b	0.221 ± 0.048 ^b
M+P	2.873 ± 0.191 ^a	0.554 ± 0.012 ^a	0.307 ± 0.027 ^a

C = untreated control, M = colonized with R. irregularis, P = infected with R. solani, M+P = colonized with R. irregularis and infected with R. solani. * Values of each column followed by the same letter are not significantly different according to Tukey’s HSD test (p ≤ 0.05), each value represents the mean of four replicates ± SD.
