Effect Of Harvest Date and Packaging In Polyethylene Films on Quality and Weight Loss In 'Golden Delicious' Apples During Cold Storage

Apple Fruits (Malus domestica Bork. cv. 'Golden Delicious') were harvested at three successive dates with intervals of one week between each date. The fruits were packaged with polyethylene films and then stored at 0±1 oC to study the effect of these factors on the quality of the fruits and their role to reduce weight loss after harvest. The natural loss of the fruit weight and quality indices: fruit firmness, total soluble solids, titrable acidity and starch content were studied.

Possibility of reducing frost injury on apple (Malus domestica cv. Golden Delicious) using Vitamin E (α-Tocopherol) and Glycerine

This study was conducted on flowering apple shoot of Golden Delicious, in order to study the effect of application of some chemical substances, α- Tocopherol (0.25%) and a mixture of α-Tocopherol (0.25%) and Glycerine 5%, at 24, and 48 hr before freezing incidence, and on best time of application on apple trees to reduce the effect of freezing.
