The trial was carried out during the season 2014, on grapevines
of Al-Baladi. Al Baladi, 20 years old, grafted onto rootstock, and trained in the trellis way, to study the influence of different levels of 4 times/season soil applied seaweed extract , on some qualitative and quantitative characteristics of Al-Baladi grapes.
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 p
ercent, 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.
