A PLURIENNIAL EXPERIENCE IN CONTROLLING PEACH FRUIT RIPENING USING DIFFERENT NATURAL SUBSTANCES

摘要

AVG and PA were applied to Redhaven peach and Stark Red Gold nectarine trees grown under field conditions. Several concentration and application times were tested over a four years period of time. Both AVG and PA controlled ethylene emission, delayedfruit flesh softening and fruit abscission. The other fruit quality parameters studied were affected as related to substances, cultivar and application schedule. The obtained results were also investigated and tentatively discussed at biochemical and molecular levels.
