Length of roots of tomato seedlings growing for 24 h in water (control) or in phytotoxic cocktails of 100% or 50% digestive fluids from fed and unfed traps of pitcher plants. Due to the lack of significant differences, we did not separate data obtained after treatment, the division into crude and heat-treaded fluids was not included. Values are average ± SD of three replications. Homogenous groups (a, b) were evaluated using Fisher’s LSD post hoc test with p < 0.5.
