Peach is a climacteric highly-perishable fruit whose post-harvest preservation relies largely on cold storage. The combination of the last with other technologies allows to extend the shelf life of this product. One alternative is the utilization of salicylic acid, a natural compound involved in many physiological phenomena such as resistance against diseases and ripening. Considering these facts, the objective of the present work was to evaluate the effect of pre-harvest application of salicylic acid solutions on the quality of ‘Chimarrita’ peaches during post-harvest cold storage. The experiment was conducted at the Federal University of Pelotas/RS, in the campus of Capão do Leão/RS - Brazil. The application of salicylic acid solutions was performed by direct pulverization on the fruits, 30 days prior to harvest. The concentrations were: 0,0 (control); 1,0; 1,5; and 2,0 mM. After harvest, the fruits were stored in a cold chamber at 1,0 ± 0,5°C and 85-90% RH, for 30 days. The analyses were performed at the following cold storage periods (plus 2 days at room temperature of 20°C to all treatments, in order to simulate commercialization conditions): 10 (+2) days; 20 (+2) days; e 30 (+2) days. The variables evaluated were: mass loss (%); flesh firmness (N); DA index; color (L, a*, b* and hue angle); wooliness incidence (%); rot incidence (%); total soluble solids (°Brix); pH; titrable acidity (% of organic acids); and ratio. The salicylic acid doses and/or the cold storage periods had significant effects on all the evaluated parameters. For most of the parameters analyzed, the intermediate dosis of 1mM (and also 1,5mM) of salicilic acid showed the most promising results. Therefore, the application of salicylic acid solutions 30 days prior to harvest is a technique which can be combined to cold storage in order to shift the quality and the shelf-life of ‘Chimarrita’ peaches.

Spraying Roomy Red grapes with benomyl 15 days before harvesting was effective than the control in decreasing decay percentage during 77 days cold storage(2-3°C). On the other hand, it was of meaningless effect on shattering and bleaching. Adding sodium bisulfite at a rate of 0.25 and 0.50 gms/skgs fruits just before storage minimized decay and shattering percentage. Simultaneously, no significant influence could be detected concerning its influence on bleaching. Sodium bisulffite reduced losses in grapes, weight as well as total soluble solids and acidity than the control and benomyl treatments. The studied parameters in grapes treated with benomyl and solium bisulfite as a pre and post-harvest treatment did not differ statistically than that of those treated with sodium bisulfite alone.

Melatonin (N-acetyl-5-methoxytryptamine) is a nontoxic biological molecule produced naturally in a pineal gland of animals and different tissues of plants. Melatonin acts as an antioxidant during postharvest storage and augments the shelf life of fruits and vegetables. Our review highlighted the role of pre and post harvest application of melatonin in extending post harvest shelf life and alleviating chilling injury in fruits and vegetables in cold storage. Review also included available information regarding biosynthesis of melatonin in plants and mode of action of melatonin in maintaining post harvest quality.
