Prohexadione-calcium Inhibits Apple, but not Peach, Tree Growth, but Has Little Influence on Apple Fruit Thinning or Quality

Fruit Self-Thinning: A Trait to Consider for Genetic Improvement of Apple Tree

In apple (Malus×domestica Borkh), as in many fruiting crops, fruit maintenance vs abscission is a major criteria for production profitability. Growers routinely make use of chemical thinning agents to control total fruit load. However, serious threats for the environment lead to the demand for new apple cultivars with self-thinning properties. In this project, we studied the genetic determinism...

Tree Growth Yield and Fruit Quality of Different Apple Cultivars Trained as Super Spindle

This study was carried out on Topaz, Cooper 39 and Muscat apple cultivars grafted on M27 rootstocks under Tokat ecological conditions during 2008 2010. The trees planted in 2.0 m x 0.5 m row spacing (10,000 trees ha-1) and trained to super spindle (SS) training system. The vegetative development, yield and fruit quality performances of the trees supported by wire – pole combination were observe...

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...

The Influence of Pine Vole Damage on Apple Tree Vigor and Fruit Yield

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...
