  • The values shown are means ± se for 11–18 plants per genotype.

  • a Height 105 d after planting, rather than the final height. Unlike the mutants homozygous for rga-28, which all began bolting immediately after flowering, these plants did not begin bolting until day 65 or later. Only a fraction of the plants (35%, 75%, 38%, and 76% for ga1-3, ga1-3/rgl1, ga1-3/rgl2, and ga1-3/rgl1/rgl2, respectively) had bolted by the end of the experiment.
