Growth suppression for prolonged marketability of tomato transplants

Vegetable transplants grown in commercial high-density trays can quickly outgrow the optimal size for shipping and transplanting, limiting transplant performance, and marketing flexibility for commercial nurseries. Abscisic acid (ABA) and uniconazole can suppress shoot growth by inducing stress-adaptive responses and inhibiting gibberellin synthesis, respectively.

Researchers at the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) evaluated the effectiveness of the two growth regulators in prolonging marketability of ‘Florida 91’ and ‘Mariana’ tomato (Solanum lycopersicum L.) transplants at commercial nursery greenhouses in Texas and Florida.
