Effect of domestication status (progenitor vs. wild) and individual seed mass on a range of functional traits

Data in the second column show the magnitude of difference between primary progenitors and other wild species. Data in the third column show the effect of logged individual seed mass on the trait, including the size of the slope, when relevant. Three‐way interactions are with status and stand type (monoculture vs. mixture). Asterisks denote significant differences: * = p <.05, ** = p <.01, *** = p <.001. All variables were natural log transformed, except for RGR, sRGR, germination success and seeding survival.

^aThis interaction was not significant after the removal of a datapoint of the crop progenitors, which had much lower NAR than other crop progenitors.
