Response variables: vegetative biomass (BIO) flower attempts (FA), changes in bolting (BOLT), days to flower (DTF), duration of flowering (DUR), male reproductive measures, pistil function, and self-fertility. Values in boldface type indicate significance at P < 0.05. Lack of a value indicates no significance and na indicates no measurement taken.
