Fruit cracking impacts the quality of sweet cherry, significantly affecting its marketability due to increased susceptibility to injury, aesthetic flaws, and susceptibility to pathogens. The effect of 1% biofilm (Parka™) application regimes on fruit cracking and other quality parameters in the '0900 Ziraat' cherry cultivar was investigated in this study. Fruit sprayed with water were served as control (U1). Fruit treated only once with biofilm three, two and one week before the commercial harvest were considered as U2, U3 and U4, respectively. Fruit treated with biofilm three, two, and one week before harvest were considered as U5; three and two week before harvest as U6; two and one week before harvest as U7; and fruit treated three and one week before harvest as U8.
In both measurement periods, the lower cracking index was obtained in biofilm-treated sweet cherry fruit. However, the firmness of biofilm-treated fruit was higher than that of the control fruit. The lowest respiration rate was observed in U7, while the highest weight was recorded in U4 and U5 than the control. The biofilm application decreased fruit coloration. The biofilm application also increased the soluble solids content of the fruit. The U2, U3 and U4 applications at harvest showed higher titratable acidity than the control. In both measurement periods, the vitamin C content of the U2, U5, U6, U7 and U8 applications was found to be higher than that of the control. The total monomeric anthocyanin of the U3 and U8 applications was higher than that of the control. Furthermore, the antioxidant activity of the U2, U3 and U5 in the DPPH, and the U7 and U8 in FRAP were measured higher thanthat of the control.
The application of biofilms has the potential to mitigate fruit cracking, prolong postharvest life of sweet cherries, and enhance fruit firmness.
水果裂果会影响甜樱桃的品质，使其易受伤、外观瑕疵和易受病原体感染，从而显著降低其市场价值。本研究旨在探讨 1%生物膜（Parka™）施药方案对‘0900 Ziraat’甜樱桃品种裂果和其他品质参数的影响。喷水处理的果实作为对照（U1）。果实仅在收获前 3、2 和 1 周分别用生物膜处理一次作为 U2、U3 和 U4。果实在收获前 3、2 和 1 周分别用生物膜处理作为 U5；在收获前 3 和 2 周处理作为 U6；在收获前 2 和 1 周处理作为 U7；在收获前 3 和 1 周处理作为 U8。
在两个测量期内，生物膜处理的甜樱桃裂果指数均较低。然而，生物膜处理果实的硬度高于对照果实。U7 的呼吸率最低，而 U4 和 U5 的果实重量高于对照。生物膜处理降低了果实的着色度。生物膜处理还提高了果实的可溶固形物含量。收获时 U2、U3 和 U4 的施用量比对照的可滴定酸度更高。在两个测量期内，U2、U5、U6、U7 和 U8 的施用量均高于对照的维生素 C 含量。U3 和 U8 的总单体花青素含量高于对照。此外，U2、U3 和 U5 在 DPPH 中的抗氧化活性，以及 U7 和 U8 在 FRAP 中的抗氧化活性均高于对照。
生物膜的应用有潜力减轻果实裂果，延长甜樱桃的采后寿命，提高果实硬度。
