چکیده

عامل‌های مهم مدیریتی پیش از برداشت تأثیر مهمی بر عمر انبارمانی و کیفیت پس از برداشت محصولات دارد. یکی از موارد مهم در این راستا میزان آبیاری محصول است. این تحقیق به‌منظور بررسی تأثیر میزان آبیاری در مزرعه روی کیفیت و مدت نگهداری قطعه‌‌های برش خوردۀ هندوانۀ رقم کریمسون سوییت انجام شد. تیمار آبیاری در دو سطح 100 درصد (شاهد) و 75درصد آب قابل‌دسترس و مدت نگهداری در پنج سطح 0، 5، 10، 15 و 20 روز در دمای 5 درجۀ ­سلسیوس در نظر گرفته شد. نتایج نشان داد، تیمار کم آبیاری باعث افزایش مواد جامد محلول، فنول کل، کاروتنویید کل و کاهش سفتی بافت شد. در طی بیست روز نگهداری برش­های تازۀ میوه، مواد جامد محلول، pH، شاخص طعم، سفتی، a*، خلوص رنگ (کروما)، میزان لیکوپن و ترکیب‌های کاروتنوییدی کاهش معنی­داری داشتند، اما در همۀ این صفات به‌جز خلوص رنگ تفاوت معنی­داری بین روز صفر و پنج دیده نشد؛ درحالی‌که اسید قابل عیارسنجی (تیتراسیون)، کاهش وزن، L*، زاویۀ هیو و فنول کل به‌طور معنی­داری افزایش یافتند. هرچند نمونه­های تنش دیده در روزهای صفر و پنج نگهداری مواد جامد محلول بیشتری داشتند، اما از لحاظ آماری تفاوت معنی­داری بین نمونه­های شاهد و تیمار کم آبیاری در روزهای صفر و پنج نگهداری مشاهده نشد. بنا بر این نتایج تنش کم آبیاری موجب بهبود برخی شاخص‌های کیفیت محصول و حفظ آن‌ها در مدت نگهداری شد، بنابراین آبیاری به میزان 75درصد آب قابل‌دسترس و 5 روز نگهداری برای قطعه‌‌های نیمه برش خوردۀ هندوانه با بیشینه حفظ کیفیت توصیه می­شود

چکیده [English]

Important pre-harvest management factors have a massive impact on increasing storage life and post-harvest quality of produces. One of the most important factors in post-harvest management is the amount of plant irrigation. This study conducted in order to evaluate the effect of irrigation level in the field on quality and storage duration of fresh cut watermelon (Crimson Sweet cultivar). The irrigation treatment was %100 (control) and %75 of available water (AW) and storage duration treatment was in 5 stages including 0, 5, 10, 15 and 20 daysin 5°C. Results showed that water stress treatment increased amount of total soluble solids (TSS), total phenols, total carotenoids and decreased texture firmness. During 20 days of storage fresh cut, TSS, pH, flavor index, firmness, a*, chroma, lycopene and total carotenoid contents significantly decreased, but all of these traits except chroma had not significant difference between 0 and 5 days. Whereas, titratable acidity, weight loss, L*, hue angle and total phenolic compounds increased significantly. Although, water stress increased TSS in 0 and 5 days, this was not statistically significant compared with control. According to these results, water stress treatment improved some quality parameters of produce and stability made stable in storage. So, %75AW and 5 days of storage for maximum quality of half fresh cut watermelon could be recommended.
