Effect of Cool Storage Period and Wrapped on Fruit Losses of Two Local Grape Varieties (Balady and Helwany)

This study was conducted to examine the effect of storage period and fruit wrapped of two local grapes varieties (Balady and Helwany) using polyethylene bags of 50 μm thickness on some losses of grapes berry . the study estimated the weight loss percent, berry shatter, berry spoilage and the total losses for the varieties as a function to storage period and packing of grapes berry. Results showed that there is a high correlation between the storage period and the weight loss, berry shatter, spoilage and the total losses of fruits, where this action started after 3 weeks of the beginning of storage. The average percents of weight loss after 100 days storage were 11.75 % and 8.43% for Balady and Helwany respectively, the berry shatter percents were 6.20% and 5.52% respectively for Balady and Helwany, the spoilage percents were 9.50% and 7.20% for Balady and Helwany respectively and the total losses for tow varieties were 20.1% and 13.63% for Balady and Helwany respectively. The previous values decreased clearly by using bags of polyethylene of 50 μm thickness as follows: 9.47% and % 6.82 for weight losses, 3.10 % and 1.8% for berry shatter, 7.20% and 3.51% for spoilage and the total losses 16% and 10.1% for Balady and Helwany respectively.

Effect of Spraying Calcium Chloride CaCl2 Treatments on Sugar Beet (Beta vulgaris L.) Manufacturer Traits of Roots in Storage

The study was conducted on winter date (15th of Febraury), during 2015 and 2016 seasons, to study the effect of spraying calcium chloride CaCl2 concentrations (2, 4, and 6%), on the manufacture traits assigned in randomized completely block design (RCBD) with four replicates.
