Abstract

Experiments were conducted in Mayagüez, Puerto Rico, to assess the effect of the physiological regulator aminoethoxyvinylglycine (AVG) as a post-harvest treatment on a lowchill peach variety grown in Puerto Rico. Fruits of 'FlordaPrince' were harvested at the 40% green peel color stage and dipped in AVG aqueous solutions (0 and 300 mg/L) for 120 or 300 seconds, allowed to air-dry, and stored at 10 or 20 °C. Five days after exposure to AVG, fruit weight loss, external coloration, acidity, and soluble solids were determined. When fruits were stored at 10° C, there was no detectable difference between AVG-treated and control fruits. However, when stored at 20° C, by five days after treatment fruits exposed to AVG for either two or five minutes were firmer than control fruits. These results indicate that, under the conditions of this research, the benefit of post-harvest AVG treatment in melting flesh peach depended more on post-treatment temperature than on time of exposure to AVG.
