Apple Harvest and Problems in Turkey

Nondestructive Determination of ‘golden Delicious’ Apple Quality and Harvest Maturity

The usefulness of nondestructive methods for measuring chlorophyll content in skin of ‘Golden Delicious’ apples and for evaluating quality parameters and fruit maturity using optical reflectance spectrometry was studied. The fruit weight, firmness, total soluble solids content and titratable acidity during vegetation period and short-term storage at 10°C of ‘Golden Delicious’ apples were measur...

Post Harvest Physical and Nutritional Properties of Two Apple Varieties

Effects of Harvest Date on Apple Fruit Quality at Harvesting and after Cold Storage

    Different dates for apples fruit harvest (Malus domestica Borkh. Cv. Fuji) were studied to determine physiochemical changes during the storage. Fuji apples were harvested from 9 September till 23 October, at five different times and stored at 0±0.5 °C and 95% relative humidity for 120 days. To determine the best harvest date for maximum quality and storability, physical and chemical paramet...

The Physiology of Apple Pre-harvest Fruit Drop

As apples ripen they begin to produce large amounts of the ripening hormone, ethylene. Ethylene stimulates fruit softening and the formation of an abscission zone in the stem. Ethylene stimulates the production of enzymes (cellulase and polyglacturonase) that break down the cell walls and the glue that holds cell walls together in the abscission zone of the stem, leaving the fruit connected to ...

Soil respiration in apple orchards, poplar plantations and adjacent grasslands in Artvin, Turkey.

In this study influence of land-use type on soil respiration was investigated in poplar plantation, apple orchard (apple trees with understory grasses) and adjacent grassland sites in Seyitler Area, Artvin, Turkey. Soil respiration was measured approximately monthly in three sampling plots in each land use type from January 2005 to November 2005 using the soda-lime technique. Mean daily soil re...
