    Effect of some postharvest treatments and controlled atmosphere (ca) storage on basic quality criteria of peaches and nectarines
    (International Society Horticultural Science, 2003-01-01) Verlinden, B.E.; Nicolai, B.M.; DeBaerdemaeker, J.; Akbudak, B; Eriş, A; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; Verlinden, BE; Nicolai, BM; DeBaerdemaeker, J
    The peach (Flavorcrest and Red Top) and nectarine (Fantasia and Fairlane) cultivars used in this study were stored in normal (NA) and controlled atmosphere (CA) conditions [(CO2%:O-2%) 3:3, 5:2, 10:2] consisting of 0+/-0.5degreesC temperature and 90+/-5% relative humidity in three years. Peaches and nectarines were subjected to some treatments (fungicide solution, low O-2 and intermittent warming treatment) either before or during storage. Physical and chemical changes (weight loss, respiration rate, fruit flesh firmness, titratable acidity, total sugar, overall appearance) were recorded at 15-day intervals during 45 day storage and after 10 day shelf life at the end of the storage. The results show that fruits of cv. Flavorcrest were stored more successfully in 5:2, fruits of cv. Red Top in 5:2 and partially 10:2, and fruits of cvs. Fantasia and Fairlane in 10:2 atmosphere combinations, compared with other treatments.

    Physical and biochemical changes during controlled atmosphere (CA) storage of cv. Granny Smith
    (International Society Horticultural Science, 2003-01-01) Özer, Mecid Hakan; Akbudak, Bülent; Verlinden, BE; Nicolai, BM; DeBaerdemaeker, J; Ertürk Ümran; ÖZER, MECİD HAKAN; ERTÜRK, ÜMRAN; Akbudak, Bülent; Uludağ Üniversitesi; Verlinden, BE; Nicolai, BM; DeBaerdemaeker, J; AAH-4101-2021; AAG-7343-2021; EJP-0187-2022
    In order to determine the possibility of controlled atmosphere (CA) storage of apple (Malus communis L. cv. Granny Smith), two trials were carried out with the fruits taken from the same place during the successive two years. Following the harvest, fruits were transported to the cold storage and then they were stored in plastic cells of 120-L volume in which the inner atmosphere could be controlled. Having completed the precooling treatment, the fruit cv. Granny Smith were stored at 0+/-0.5degreesC and 90-95% relative humidity (RH) storage conditions under different CA combinations [(CO2%:O-2%) 0:21; normal atmosphere (NA)-control, 3:1, 3:1.5, 3:2 and 3:2.5]. After the storage period, they were kept at 20+/-2degreesC and 60-65% RH for 5 days so as to determine their shelf life. Some physical and biochemical analyses such as weight loss (%), respiration rate (Mg CO2/kg h), titratable acidity (TA) (%), pH, water soluble solids (WSS) (%), fruit flesh firmness (FFF) (lb), pectin esterase (PE) activity (ml/h), fruit skin colour (L, a, b) were conducted on samples which were taken at certain intervals during storage and shelf life periods. As a result, all CA applications were found better compared with the control application in cv. Granny Smith stored for 210+5 days. Among CA applications, 3:1.5 combination was determined to be better than the others.
