Codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae) is a major fruit feeding pest of apples. Understanding susceptibility differences of various apple cultivars to CM oviposition is an important step in developing resistant varieties as well as monitoring and management strategies for this pest in apple orchards planted with mixed-cultivars. In this context, oviposition preferenc...

fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in dr. nakhjavani field station, orumieh, iran, in 2008 and 2009 growing seasons. apple cultivars included: red spur, red chief, golden spur, yellow spur, fujii, red delicious, cooper spur, red cooper spur, jonathan, golden delicious, oregon spur, jonagold. the experimental desi...

The content of chlorogenic acid was studied in three scab resistant apple cultivars (‘Topaz’, ‘Gold Rush’, ‘Goldstar’) and two scab susceptible ones (‘Golden Delicious Weinsberg’, ‘Golden Delicious Clone B’) growing in Laboratory Field of the Biotechnical Faculty in Ljubljana. The leaf samples were collected four times in 30 day intervals between 12 June and 10 September 2001 and analysed using...

this study was carried out to examine the effects of kaolin spray for reducing the adverse effects of high radiation and temperature, especially on fruit sunburn in apple. treatments were four concentration of kaolin (0, 2, 4, and 6%) and two important and commercial apple cultivars in fars province; ‘golden delicious’ and ‘starking delicious’. trees physiological parameters, fruit sunburn and ...

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...

In the present study, evolution of apple color (L* and a/b), the accumulation of anthocyanins and the activity of the related enzymes, phenylalanine ammonia-lyase (PAL), chalcone isomerase (CHI), dihydroflavonol4-reductase (DFR) and UDP-Glucose: flavonoid-3-O-galactosyl transferase (UFGT), were investigated in bagged non-red apple cultivars ('Granny Smith' and 'Golden Delicious') and red apple ...
