چکیده

پژوهش حاضر با هدف بررسی تأثیر دو نوع پاکت کاغذی سفید تک‌لایه و سبز دولایه بر آفتاب‌سوختگی و کیفیت میوۀ انار رقم رباب نیریز انجام شد. پاکت‏ها 35 روز پس از تمام‌گل روی میوه‏ها قرار گرفتند. نتایج نشان داد که قرار‌دادن پاکت سفید سبب افزایش اندازه و وزن میوه و وزن دانه نسبت به تیمار شاهد شد. در مقابل قرار‌دادن پاکت سبز سبب کاهش اندازه و وزن میوه‏ها نسبت به تیمار شاهد شد. در‌حالی‌که تیمار پاکت سبز سبب کاهش محتوای آب پوست شد، بین تیمارها اختلاف معناداری در محتوای آب هسته مشاهده نشد. پاکت سبز رسیدن را به تأخیر انداخت. محتوای آنتوسیانین کل و فنل کل با پاکت‌گذاری کاهش یافت. فعالیت آنتی‌اکسیدانتی میوه‌های پاکت سفید افزایش و پاکت سبز کاهش یافت. در بین تیمارهای انجام‌شده، بالاترین آفتاب‌سوختگی در تیمار شاهد مشاهده شد. پاکت‏های سفید و سبز سبب کاهش شدت و درصد آفتاب‌سوختگی نسبت به تیمار شاهد شدند. بنابراین، استفاده از پاکت سفید به‌دلیل افزایش کیفیت و همچنین کاهش آفتاب‌سوختگی در انار رقم رباب نیریز می‏تواند مفید باشد. پاکت سفید تک‌لایه می‏تواند به‌منزلۀ ابزاری مفید برای افزایش کیفیت میوه و کنترل آفتاب‌سوختگی برای تولید‌کنندگان انار استفاده شود.

چکیده [English]

Experiments were conducted to test the effects of two different paper bags, white single- and green double-layers, on fruit quality and sunburn of pomegranate (Punica granatum cv. Rabab Neiriz). Young fruits, at 35 days after full bloom, were covered by bags. The results showed that white single layer bag increased size and weight of fruits and aril weight in comparison to those of control. In contrary, green bag reduced size and weight of fruits. Green bag reduced peel water content; however, there were no significant differences in aril water content. Green bag delayed fruit ripening. Results indicated that bagging significantly reduced total phenolics and anthocyanin content. Antioxidant activity increased in white bags covered fruits, and reduced in those of green bag covered ones. Bagging treatments decreased sunburn intensity and sunburn areas. White bag was the most effective treatment for increasing quality and reducing sunburn in pomegranate fruit cv, Rabab Neiriz. Therefore, the use of white bags, due to the enhancing of quality and decreasing of sunburn, can be useful for pomegranate cv. 'Rabab Neiriz'. This could then serve as a useful tool for pomegranate growers to use white single layer bags to increase fruit quality and control sunburn.
