in this study, the amount of total phenol, chlorogenic acid, catechin, quercetin, phloridzin, cyanidin and antioxidant activity of apple (malus domestica) skin and flesh of six iranian cultivars, including: ‘golab kohanz’, ‘sib torsh dirras’, ‘ghara yapragh’, ‘torkman’, ‘ghezel alma’ and ‘abbasi mashhad’, and four commercial cultivars including: ‘golden delicious’, ‘red delicious’, ‘braeburn’ a...

fruit browning and tissue softening due to damages during handling, quality losses and water loss are the major limiting factors reducing postharvest life of early ripening apples. in this study, the effect of salicylic acid (sa) on fruit quality of apple cv ‘golabe-kohanz’ during postharvest life were investigated. harvested fruits were immersed in zero, one, two and four mm sa and were mainta...

the effects of a nano-emulsion chitosan-based coating on enhancing the shelf-life and quality of golab kohanz apples were studied. the nano-emulsion coating containing chitosan with a concentration of 2000 ppm was applied for coating of golab kohanz apples. coated and uncoated apples were packed in normal packaging cardboards and kept at 2 ± 1 °c with a relative humidity within 80-85%. flesh fi...

the internal infections of erwinia amylovora have important roles for disease beginning in the spring and dissemination of inoculum through infected vegetative planting material and nursery trees. in this study, we survey internal infection of erwinia amylovora in symptomless commercial apple cultivars in karaj and damavand cities, using optimized diagnostic methods such as plating on semi sele...
