Appendix 3
Result of a one-way Ancova with stage of architectural development (ASD = 2) as main factor and relative irradiance (DPFrel, %) as covariables applied to Tachigali melinonii (Harms) Barneby. F -value, level of significance (P) and coefficient of determination (r2) of the model are given. DPFrel, LMA and Jmax a were log transformed prior to analysis.Values of adjusted means (± standard error) were also given (covariate mean = 21%) for the three stages of Architectural development (ASD). Cm and thickness were analyzed with a separate slope model. Vcmax m, Jmax m and Rd m were not linearly correlated with DPFrel and thus they were analyzed with a one way ANOVA. Significant levels: ns, P > 0.05; * P < 0.05; ** P < 0.01 and *** P < 0.001.
