Table 1. F-values and significance levels of three-way nested ANOVAs of the relative growth rate (RGR) and the resources availability of host plants with fixed factors parasitism (present or absent) and origin (invasive or native), and random factor species pairs (nested with origin).

Factors	Degree of freedom (df)	RGR	Specific leaf area (SLA)	Specific fine root length (SFRL)	Specific fine root surface area (SFRSA)
Parasitism (P)	1,64	72.301 ***	45.739 ***	22.095 ***	19.898 ***
Origin (O)	1,4	1.673	2.070	0.383	0.351
P×O	1,64	0.108	5.316 *	0.765	3.245 *
Species pairs (nested with origin)	4,64	21.298 ***	24.585 ***	31.977 ***	13.777 ***

Values in bold are significant at p<0.05; Significance indicated as follows:

^* p<0.05,

^** p<0.01,

^*** p<0.001.
