چکیده
به­منظور ارزیابی کیفیت و کمیت ارقام مهم تجاری انار ایران در شرایط اقلیمی یزد، میوه­های 12 رقم شامل: ارقام اردستانی مه­ولات، بجستانی، شیشه­کپ فردوس، نادری بادرود، قجاق قم، گل تفتی، شیرین شهوار، رباب نی­ریز، ملس یزدی، ملس ساوه، ملس یوسف­خانی و خزر بردسکن در مرحله بلوغ تجاری برداشت و از نظر صفات مهم کمی و کیفی بررسی شدند. نتایج نشان داد بین ارقام از نظر وزن میوه، خصوصیات رنگ پوست و آریل (CIE L*, a*, b* و زاویه هیو)، مقدار مواد جامد محلول، درصد اسید قابل تیتر، فعالیت آنتی­اکسیدانی و مقدار آنتوسیانین عصاره تفاوت­های مشخصی وجود داشت. در این بین بیشترین وزن میوه در رقم شیرین شهوار اندازه­گیری شد، این رقم همچنین دارای کمترین درصد اسید قابل تیتر و بیشترین شاخص طعم در بین ارقام بوده و رنگ روشنی نیز نشان داد، هرچند روشن­ترین رنگ در بین ارقام در رقم نادری بادرود ارزیابی شد. در همین حال رقم ملس یزدی بر اساس خصوصیات رنگی پوست و آریل، مقدار آنتوسیانین عصاره و خصوصیات طعم بهترین رقم در بین ارقام بود. هرچند ارقامی همانند شیشه­کپ فردوس نیز خصوصیات کیفی مناسبی نشان دادند. همچنین همبستگی بین صفات بررسی و روابط معنی­داری بین خصوصیات رنگ و مقدار آنتوسیانین و یا بین ظرفیت آنتی­اکسیدانی و مقدار فنل و یا مقدار آنتوسیانین مشاهده شد.

چکیده English

In order to evaluate the quality and quantity of some important commercial Iranian pomegranate cultivars, in the climatic conditions of Yazd, the fruits of 12 cultivars including: Ardestani Mahvalat, Bejestani, Shishekap Ferdows, Naderi Badroud, Qajaq Qom, Gel Tafti, Shirin Shahvar, Robab Neyriz, Malase Yazdi, Malase Saveh, Malase Yousefkhani and Khazar Bardaskan were harvested at commercial maturity stage and were evaluated for important quantitative and qualitative traits. The results showed, there were significant differences among the cultivars in terms of fruit weight, skin and aril color properties (CIE L *, a *, b * and Hugh angle), soluble solids content, titratable acidity, antioxidant activity and anthocyanin content. Meanwhile, the highest fruit weight was measured in Shirin Shahvar cultivar, this cultivar also had the lowest titratable acidity and the highest taste index among the cultivars, and also this cultivar showed a bright color, however, the brightest color among the cultivars was observed in Naderi Badroud. Based on the skin and aril color properties, anthocyanin content and fruit taste, Malase Yazdi was the best among the cultivars. However, cultivars such as Shishekap Ferdows, also showed good quality characteristics. Also the correlations between traits was investigated and significant relationships were observed between color properties and amount of anthocyanin or between antioxidant capacity and amount of phenol or amount of anthocyanin.
