↵a Values represent the mean shoot apical meristem diameter ± standard error of plants collected simultaneously at the onset of bolting (see Methods).
↵b The percentage of plants showing a distinct ring shape to the meristem.
↵c The percentage of plants showing a severe loss of organogenesis.
↵d n indicates the number of measurements used to determine size.
