Cultivar and fruit size influence bruise susceptibility and some physical properties of apple fruit

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...

Apple Fruit Pectic Substances.

1. The pectic substances of apple have been extracted and separated into a pure pectinic acid and a neutral arabinan-galactan complex by precipitation of the acidic component with ethanol and with cetylpyridinium chloride. 2. The composition of the fractions has been determined. The pectinic acid contained galacturonic acid, arabinose, galactose, rhamnose, xylose and several trace sugars. 3. Tr...

Shade effects on growth, flowering and fruit of apple

Light is a critical resource needed by plants for growth and reproduction. A major portion of the apple (Malus x domestica Borkh.) tree’s canopy is subjected to shade during most daylight hours each day and such shade may affect productivity. The current research determined effects of morning, afternoon, and all-day shading on processes that are significant to orchard productivity. In 1996 ‘Gin...

Tissue-specific expression of SORBITOL DEHYDROGENASE in apple fruit during early development.

Sorbitol, the primary photosynthate and translocated carbohydrate in apple (Malusxdomestica Borkh.), is converted to fructose by sorbitol dehydrogenase (SDH; EC 1.1.1.14) which is active in apple fruit throughout development. In the apple genome, nine SDH genes have been isolated and their sequences characterized, but their individual expression patterns during apple fruit set and development h...
