The concentrations (mean values + 1 SD, n = 6) of tannin (A), total phenolics (C), total flavonoids (E), saponins (G) and alkaloids (I) in different-aged invasive B. pilosa plants infected and not infected by C. australis, and the PR of tannin (B), total phenolics (D), total flavonoids (F), saponins (H) and alkaloids (J) in stems of the different-aged B. pilosa plants to the parasitic C. australis. Different letters indicate significant difference between host plants of different ages at P < 0.05. F-value and significance levels are given. Asterisks indicate significant difference in means between plants within the same age class at *P <0.05, **P <0.01 and ***P < 0.001, respectively.
