图2 专食性-广食性天敌比例对喜旱莲子草入侵地种群(浅色)和原产地种群(深色)生长性状的影响。图中标注了专食性-广食性天敌比例与来源地交互作用(SGR × O)的显著性、线性拟合系数以及不同来源地组间差异的显著性: ns, 不显著; * P < 0.05; ** P < 0.01; *** P < 0.001。

Fig. 2 Effect of the specialist-to-generalist ratios on the growth traits between invasive (light) and native (dark) populations of Alternanthera philoxeroides. The significance of the interaction between specialist-to-generalist ratio and origin (SGR × O), the linear fitting coefficient, and the significance of the different origin is marked in the figure. ns, P > 0.1; * P < 0.05; ** P < 0.01; *** P < 0.001.
