An attempt has been made to assess the UV-B-protective capacity of phenolic compounds accumulated in superficial structures of plants using apple fruit as a model. Two apple (Malus domestica Borkh.) cultivars (Braeburn and Granny Smith) differing in response to high fluxes of solar radiation were selected and exposed to increasing doses of UV-B radiation. The extent of UV-B-induced damage to ph...

Single warmings of ‘Cortland’, ‘Delicious’, ‘Granny Smith’ and ‘Pacific Rose’ apples to 20°C for 0–9 days after cold storage of 0–27 days were tested as a potential non-chemical method to control superficial scald development. Only in ‘Granny Smith’ was scald development reduced to commercially acceptable levels by warming, and even for this cultivar the response varied among growing regions. W...

Bagged fruits of green apple cultivar "Granny Smith" have been found to turn cardinal red after debagging during fruit-ripening in the Loess Plateau region of China. To understand this phenomenon at post-transcriptional level, we have investigated the roles of microRNAs (miRNAs) in response to debagging. Three small RNA libraries were primarily constructed from peels of "Granny Smith" apples su...

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 ...

Apple is one of the most important fruits in temperate zones with a long post-harvest life during cold storage. A factorial experiment, in a randomized completely block design was used to investigate the preharvest application of Iron (0, 500 and 1000 mg Fe-EDDHA per tree) and nitrogen (0, 48 and 96 g ammonium nitrate per tree( on some postharvest qualitative characteristics in "Red spur" and "...

The possible relationship of branching habit to cytokinin content of apple shoots (Malus domestica Borkh.) was investigated. One-year old apple shoots are acrotonic (distal branching), more strongly so in Granny Smith than in Braeburn. In the ®rst trial, long, 1-year old Granny Smith and Braeburn apple shoots were sprayed on 29 August 1995 to break rest with dinitro-o-cresol (DNOC) oil (5%). Th...

We compared the eating quality of a new apple cultivar, ‘GoldRush,’ with ‘Golden Delicious’ (one of its parents), ‘Fuji,’ and ‘Granny Smith’ (the latter two often used for fresh-cut apple slices). We also compared a commercial with an in-house processing treatment, NatureSeal for apples and Produce Quality and Safety Laboratory (PQSL), respectively. Intact apples that had been stored for about ...
