Relationship between chromatic and achromatic leaf cues and plant size, density, number of flowers and location.

Correlations between colour and plant size, density and C:N are Spearman’s rank correlations (ρ). Differences in colour between plants with and without flowers and between plants in different counties were analysed using ANOVA (F) and Kruskal-Wallis tests (χ2). For correlations between colour and C:N, n = 179. For all other analyses, n = 548. Significant results following correction with the Benjamini-Hochberg procedure (FDR = 0.05) are in bold (P values shown are unadjusted).Relationship between chromatic and achromatic leaf cues and plant size, density, number of flowers and location.
