“…In addition, calcium protects cell walls against degrading enzymes (Manganarys et al, 2007). Addition of calcium improves rigidity of cell wall and prevents enzymes such as polygalacturonase from reaching their active sites (John, 1987), therefore increasing firmness, retarding tissue softening and prolonging harvest season (Cheour et al, 1991;Marzouk and Kassem, 2011). This effect can be explained by the formation of cross links between the carboxyl groups of polyuronide chains found in the middle lamella of the cell wall.…”

Chinese jujube is among the important medicinal plants grown in Iran. Its valuable fruit have a short post-harvest life. Delaying of quality reduction for few days can help maintaining the shelf life of fresh jujube fruit. The current study was conducted to investigate the possible effects of pre-harvest foliar application of salicylic acid (0, 2 and 4 mM) and calcium nitrate (0, 1 and 2%) on physico-chemical characteristics and shelf life of fresh jujube fruit during storage at 10-days intervals, for 40 days. Results indicated that salicylic acid and calcium nitrate played an important role in maintaining and extending post-harvest quality of fresh jujube fruit, as both substances increased fruit firmness, titrable acidity, total phenolic content, antioxidant activity, ascorbic acid and catalase enzyme, but reducing total soluble solids. The highest total phenolic content (2.38 µg gallic acid/gFW), antioxidant activity (76.73 mmol Trolox/g), ascorbic acid (222.4 mg/100g FW) and catalase enzyme (16.67 U. mg -1 protein), as well as the lowest total soluble solids content (23.11%) were observed when salicylic acid 4 mM was used. Furthermore, maximum fruit firmness (4.22 N) was obtained in the treatment containing calcium nitrate 2%. Treatment containing salicylic acid 2 mM and calcium nitrate 2% had the highest amount of titrable acidity TA (0.45 %). Based on the results, reducing trends of some components like ascorbic acid, antioxidant and phenol, were very fast, even when using salicylic acid and calcium nitrate; their application could cause a delay in these processes, but the quality reduction found could not be compensated. In other characteristics that had a slower quality reducing trend, the application of salicylic acid and calcium nitrate could cause at least a 10-day delay in the reduction of the amounts of these attributes.

“…However, it was evident that the most effective concentration in this concern was 200ppm. It should be realized that the obtained results for GA3 may be related to a part role played by GA3 in lowering the respiration rate, 30,31 it's striking effect in delaying the senescence, 32,33 increasing the content of cuticle and sustain the integrity of membranes, 30,31,34 which reduce the water loss and increasing the cell-wall thickness that protect the fruits from the fungal infection, 35,36 delaying the loss of chlorophyll and consequently retarded the appearance of brown color. [37][38][39][40][41][42] Concerning the changes occurred in the chemical characteristics, it is obvious that GA3 kept comparatively the favorite highest contents of T.S.S, total sugars, inulin, ascorbic acid and lowering the enzyme activity of polyphenol oxidase during all the storage periods.…”

“…[37][38][39][40][41][42] Concerning the changes occurred in the chemical characteristics, it is obvious that GA3 kept comparatively the favorite highest contents of T.S.S, total sugars, inulin, ascorbic acid and lowering the enzyme activity of polyphenol oxidase during all the storage periods. These results may be attributed to the depression in moisture loss, respiration rate 35,36,43,44 by GA3 and conversion of insoluble solids to simpler forms. 42,45 Considerable attention has been paid to the obtained results of potassium sorbate, where the treatment of potassium sorbate ranked second showing less unmarketable percentage, higher visual quality, less color degradation, higher contents of T.S.S, total sugars, inulin, ascorbic acid and less polyphenol oxidase activity.…”

Fresh-cut heads of globe artichoke cultivar "French Hyrious" were dipped in solutions of Gibberellic acid (GA3) at 100, 200 and 300ppm, Potassium sorbate (PS) at 1, 2 and 3% and edible coating Chitosan at 1, 2, and 3 % for 5 minutes then placed in polyethylene trays that covered with polypropylene film which closed thermally and stored at 0ºC and 95% R.H. GA3 exhibited comparatively the most obvious results during storage in lessening the deterioration of loss in weight, unmarketable percentage, T.S.S, inulin beside lowering the activity of polyphenol oxidase enzyme. The maximum T.S.S % was obtained from gibberellic acid at 200ppm, potassium sorbate 1% and chitosan 3%. The application of gibberellic acid led to keep the highest total sugars content at 200ppm followed by potassium sorbate at 1% and finally chitosan at 2%. The maximum inulin content happened due to the application of gibberellic acid at 200ppm followed by potassium sorbate 3% and at least was chitosan at 3%. The highest ascorbic acid was obtained from the application of GA3 at 200 ppm, 3% potassium sorbate and 2% chitosan respectively. Gibberellic acid at 200ppm followed by potassium sorbate 1 % exhibited the least enzyme activity while chitosan at 1 %reflected the highest activity during the various storage periods.

“…), which is the most economically important postharvest disease of grapes 7 . Foliar sprays of CaCl 2 twice at the pea and veraison stages of berry development improved the berry firmness, shelf life, and fruit quality of grapes 20 , whereas Ca application after veraison was less effective in improving berry Ca concentration and fruit quality during storage 7 . A contradictory result was also shown; foliar and soil applications of CaCl 2 had no effect on leaf or fruit Ca concentration, yield, and berry sugar concentration 5 .…”
