Path analysis of the effect of standardized flowering start, and floral display traits (No. of flowers, flower size, scape height) and proportion of damaged flowers and fruits on relative fitness of P. alpicola plants under supplemental hand pollination treatment (n = 165) at Lulang, China in 2016. Model A: Four floral traits play direct effects on relative fitness (χ2 = 153.3, df = 4, P < 0.01, AIC = 2007.7, loglikelihood = −998.8); Model B: Four floral traits play indirect effects on relative fitness through the proportion of damaged flowers and fruits (χ2 = 198.5, df = 9, P < 0.01, AIC = 2441.7 loglikelihood = −1209.8). Significant path coefficients are signed with asterisks (*P < 0.05, **P < 0.01).
