Urunlerin depoya alinmalarindan sonra muhafaza suresi icerisinde urunlerde ozellikle latent enfeksiyon kaynakli fungal gelisimlerin gozlemlenmesi mumkundur. Hastalik gelisimi icin uygun olan muhafaza sartlarinda urunlerde ticari kayba neden olan curumeler ve deformasyonlar meydana gelebilmektedir. Bunlari onlemek icin hastalikli meyvelerin depo kosullarinda tespit edilerek izole edilmesi oldukca onemlidir. Bu calismada Diplocarpon mespili enfeksiyonu gorulen armut meyvelerinin depo kosullarinda saglikli meyvelere hastalik tasimasinin ve inokulum kaynagi olmasinin onune gecilmesi icin goruntu isleme yontemleri ve destek vektor makinesi kullanilarak bir leke analiz algoritmasi gelistirilmistir. Gelistirilen yontem ile armut meyvesinin yuzeyinde gelisimine devam eden ve lezyon capi gelisen aktif alanlarin pasif leke alanlarina gore daha yuksek bir dogrulukla saptanabildigi tespit edilmistir.

Different concentrations of sodium hypochlorite, peracetic acid, hydrogen peroxide and Citrox® were used in in vitro experiments whereby the toxicity of disinfectants on B. cinerea and P. expansum spore germination and germ tube elongation was investigated. Citrox® was the only disinfectant containing organic acids and flavonoids. The in vitro experiments demonstrated that disinfectants were effective in inhibiting spore germination and germ tube elongation. In in vivo experiments, fruits were inoculated with a suspension containing 1 × 10 6 cfu/mL B. cinerea and P. expansum spores and hydrocooled with appropriate disinfectant concentrations. Total microbial, fungal, and bacterial populations on fruit surfaces and in the water used for processing were reduced by all disinfectant applications. Fruits were packed in modified atmosphere packages and stored at 1°C for 30 days and for 4 additional days on a shelf at 20°C. During cold storage, fruits were evaluated in terms of phytotoxicity, and it was observed that Citrox®, hydrogen peroxide, and ozonated water applications cause phytotoxicity in the both the stem and fruit. In contrast, no phytotoxic reaction was observed in sodium hypochlorite and peracetic acid applications. Fruit decay did not occur during cold storage but was seen during the shelflife period. Fruit decay was significantly reduced by sodium hypochlorite and peracetic acid applications. Sodium hypochlorite and peracetic acid applications within a hydrocooler were found to be efficient in preventing postharvest diseases of sweet cherries.

Urunlerin depoya alinmalarindan sonra muhafaza suresi icerisinde urunlerde ozellikle latent enfeksiyon kaynakli fungal gelisimlerin gozlemlenmesi mumkundur. Hastalik gelisimi icin uygun olan muhafaza sartlarinda urunlerde ticari kayba neden olan curumeler ve deformasyonlar meydana gelebilmektedir. Bunlari onlemek icin hastalikli meyvelerin depo kosullarinda tespit edilerek izole edilmesi oldukca onemlidir. Bu calismada Diplocarpon mespili enfeksiyonu gorulen armut meyvelerinin depo kosullarinda saglikli meyvelere hastalik tasimasinin ve inokulum kaynagi olmasinin onune gecilmesi icin goruntu isleme yontemleri ve destek vektor makinesi kullanilarak bir leke analiz algoritmasi gelistirilmistir. Gelistirilen yontem ile armut meyvesinin yuzeyinde gelisimine devam eden ve lezyon capi gelisen aktif alanlarin pasif leke alanlarina gore daha yuksek bir dogrulukla saptanabildigi tespit edilmistir.
