Natural Sources of Spraying to Preserve Apple Fruit Quality during Post-Harvest

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...

Effect of calcium chloride treatment on post harvest quality of peach fruit during cold storage

This study was carried out on the effectiveness of calcium chloride (CaCl2) treatments on the post harvest quality of peach fruits during cold storage at 10oC and 75 ± 5% RH. Different solutions of CaCl2 such as 1% (T1), 2% (T2) and 3% (T3) were prepared and the fruits were dipped for five minutes, while (To) was left with out calcium chloride treatment as control. The fruits were packed in cor...

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 ...

On the Use of the Own Plant's Defence Compounds to Maintain the Post- Harvest Fruit Quality

This work demonstrates that the own plant defence compounds, like resveratrol in grapes, can be used as a natural and ecological alternative to chemical pesticides. An extract from vine leaves was used to maintain the quality of post-harvested grapes. Specifically, an extract (95% water and 5% ethanol) of such leaves was prepared and, subsequently, different bunches of grapes were immersed in i...
