A group of plant geneticists discovers a mutant plant that has a deficiency in gibberellin production. All other hormones, including auxins, cytokinins, florigens, ethylene, and abscisic acid, are produced in normal quantities and are not directly affected by this mutation. Based on this scenario, the mutant plant most likely exhibits:
