Pre-harvest and post-harvest techniques to optimize the fruit quality-fruit thinning. Bioregulators.
Objectives:
- Establishment of the bioactive substance effects on fruit chemical composition, flesh firmness, fruit color and chlorophyll fluorescence; studies on the synthesis, transformation and translocation of the assimilates from leaves to fruits, extending the fruit shelf live and improving of the fruit quality;
- Reduction of the vegetative growths on sweet cherry, apple and plum under growth retardants application;
- Fruit set improvement on self-pollinating cultivars/with pollination deficits by application of fruit set stimulators;
- Overcoming the alternate bearing by chemical thinning and crop load adjustment on apple, peach and plum species;
- Extending fruit shelf-life, reducing crop losses during the storage and improving fruit quality;
- Technological parameters optimization in fruit processing to obtain fruit based products with valuable biochemical properties.
Achievements::
-Technological sequences of foliar nutrients application to improve fruit quality before and after harvest;
- Methodology to estimate the fruit senescence during the storage period by chlorophyll fluorescence assessment;
- Establishing optimal technical parameters to maintain fruits quality during the storage;
- Innovative technologies for fruit processing (mainly dehydration and juicing).
