I am using the concept of plant functional traits (Cornellisen et al., 2003) in a paper. Considering descriptions for whole plant traits (life history; life form; growth form; plant height; clonality; spinescence; branching architecture, root-mass fraction (Pérez-Harguindeguy et al., 2013), where does "phytochemical profile" fit in? I can see how it isn't considered a "whole plant trait", and that it influences trait expression, but is that the extent of it? I guess I am trying to make sure that I am thinking about this correctly.
