قُطفت ثمار التفاح Bork domestica Malus صنف غولدن ديليشس في ثلاثة مواعيـد متتاليـة
بفارق أسبوع واحد بين الموعد و الآخر و غُلفت برقائق البولي إثيلين و خُزنت في درجـة حـرارة 0±1ْ م
لدراسة تأثير هذه العوامل في جودة الثمار و دورها في خفض فاقد الوزن الحاصل فيها بعد القطاف. درس
الفقد الطبيعي الحاصل في وزن الثمار فضلاً عن مؤشرات الجودة و هي صلابة لب الثمار، المواد الصـلبة
الذائبة الكلية، الحموضة القابلة للمعايرة و محتوى النشاء.
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.
