Title Of Article :
Effects of Pre-harvest Putrescine Treatments on Cold Storage Life and Quality of Sweet Cherry cv. 0900 Ziraat
Abstract :
Objective: Effects of pre-harvest putrescine (PUT) treatments on storage life and quality of 0900 Ziraat sweet cherry were investigated. Material ve Methods: Different doses (2.5, 5 and 7.5 mM) of PUT and Tween-20 (0.01 %) (as a surfactant) were sprayed on sweet cherry trees as well as distilled water with Tween-20 (pre-harvest control group) 3 weeks before commercial harvest. Sweet cherry fruit were harvested at optimal harvest maturity and placed in modified atmosphere packaging (MAP). Packaged fruit were stored at 0 °C and 90±5 % relative humidity for50 days. The weight loss, soluble solids content, titratable acidity, fruit firmness, fruit stem and skin color, respiration rate, gas composition in packages and sensory evaluation were determined initially and at 10 day intervals. Results: All doses of PUT treatments gave better results than control samples for investigated quality parameters. The best results in term of stem and skin color and sensory evaluation were obtained from fruit treated with 2.5 and 5.0 mM PUT. Conclusion: Fruit treated with PUT could be stored with marketable quality for 40 days but control samples only 30 days. If it is demanded unblemished fruit surface without pitting, these periods can be taken into consideration as 20 and 30 days, respectively.
