Growth-regulator-induced alleviation of chilling injury in green and red bell pepper fruit during storage.

 

Capsicum annuum cv. Maor plants were sprayed at full bloom with paclobutrazol (50 or 100 mg/litre), uniconazole (20 or 50 mg/litre) or mefluidide (20 or 50 mg/litre). Mature-green and red fruits were harvested 4 and 8 weeks after spraying, respectively. Paclobutrazol and uniconazole, but not mefluidide, affected plant growth and fruit morphology. All 3 growth regulators alleviated chilling injury that developed on green and red fruits after storage for 28 days at 2 deg C. Potassium leakage was lower from tissue discs, and weight loss less, from treated than from control fruits. Ethylene and CO2 production at 20 deg were similar in control and paclobutrazol-treated fruits after 28 days at 2 deg . These results are consistent with previous findings which showed that these growth regulators are able to increase tolerance to low temperatures in whole plants.
