ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...

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 form of the Apple tree is decided by the organ position of the tree, it affects not ONLY the relationship between the vegetative growth and the fruit production, but also the fruit quality. In this research, the continuous growth for 3 years was gotten with polhemus fastrak, and the apple tree model was built in the POV-ray to simulate the interception of the sunlight. A mathematic model wa...

background: it was found that, climatic conditions and fruit ripeness are important factor for the occurrence and intensity of superficial scald. 1-mcp is an inhibitor of ethylene action in plants and inhibits many ripening related processes along with the production of ethylene and volatiles. objective: apples are often held for several months at low temperature either in air (ra) or in contro...

NAD(+)-dependent sorbitol dehydrogenase (NAD-SDH, EC 1.1.1.14), a key enzyme in sorbitol metabolism, plays an important role in regulating sink strength and determining the quality of apple fruit. Understanding the tissue and subcellular localization of NAD-SDH is helpful for understanding sorbitol metabolism in the apple. In this study, two NAD-SDH cDNA sequences were isolated from apple fruit...

Annual yields per tree for ‘Starkspur Supreme Delicious’ apple (Malus domestica Borkh.) trees on nine size-controlling rootstock were related linearly to number of fruit per tree at harvest each year, independent of rootstock. Mean fruit weight was inversely and less closely related to number of fruit per tree when adjusted for tree size (fruit load). Annual yield-fruit count data for 9 years a...

Soluble sugar and malic acid contents in mature fruits of 364 apple accessions were quantified using high-performance liquid chromatography (HPLC). Fructose and sucrose represented the major components of soluble sugars in cultivated fruits, whilst fructose and glucose were the major items of sugars in wild fruits. Wild fruits were significantly more acidic than cultivated fruits, whilst the av...

INTERNATIONAL DWARF FRUIT TREE ASSOCIATION Apple yield and fruit quality are the end result of myriad cultural practices (e.g., pruning, thinning, spraying), environmental inputs (e.g., light, carbon dioxide, water, nutrient supply) and physiological processes (e.g., leaf area development, light interception, photosynthesis, respiration). All of them are truly essential contributors to fruit pr...

BACKGROUND Chlorantraniliprole formulated as a 350 g kg(-1) WG (Altacor 35WG) for management of apple maggot Rhagoletis pomonella (Walsh), blueberry maggot R. mendax Curran and cherry fruit fly R. cingulata (Loew) (Diptera: Tephritidae) was evaluated in laboratory assays and field trials. RESULTS A tarsal contact toxicity bioassay showed that a surface residue of 500 mg L(-1) of chlorantranil...

The proverb “An apple a day keeps the doctor away” addressing the health effects of the fruit. Apple is the most important temperate fruit crop and has been cultivated in Asia and Europe from antiquity. Apple is a fruit of temperate climate and it is native to many parts of Europe and Asia [1]. Worldwide, apple is the four most broad produced short-lived fruits, and in more than 94 countries, i...
