چکیده

هدف اصلی این پژوهش، بررسی مقدار تولید قره­قات (Ribes biberistentii Berl. & DC) و نقش آن در اقتصاد خانوارهای روستایی ارسباران است. این پژوهش با استفاده از پژوهش­های کتابخانه­ای و بررسی­های میدانی در تابستان 1396 در جنگل‌های ارسباران انجام شد. با استفاده از پرسشنامه، اطلاعات اقتصادی اجتماعی از 32 بهره­بردار این گونه در روستای کلاسور واقع در حوزۀ آبخیز ایلگنه­چای ارسباران جمع­آوری شد. از تحلیل همبستگی پیرسون بین مشخصه­های مختلف درخت با مقدار میوه تولیدی برای تحلیل رگرسیون انجام شد. با استفاده از مصاحبه با افراد محلی، مشخصه­هایی از قبیل قیمت میوۀ خام و فرآوری­شده، نوع و روش فرآوری، مقدار برداشت و مصرف میوۀ خام و فرآوری­شده، نحوه فروش و بازاررسانی و کاربردهای دارویی این گونه‌ بررسی شد. نتایج اندازه­گیری میوه­های برداشت‌شده قره­قات نشان داد که وزن 1000 میوه قره­قات، 240 گرم بود. مقدار میوه تولیدی هر پایه با مشخصۀ میانگین قطر تاج، بالاترین مقدار همبستگی (767/0) در سطح یک­درصد معنی­داری را داشت. نتایج نشان داد که مهم­ترین مصرف دارویی قره­قات، مربوط به میوه آن بوده که برای درمان فشارخون توسط مردم محلی استفاده می­شود. با توجه به قیمت میوۀ خام و مقدار برداشت، ارزش اقتصادی برداشت قره­قات برای 32 خانوار بهره­بردار در سال 1396، 2/19 میلیون تومان بود. میانگین ارزش اقتصادی سالانه برداشت و فروش سالانه قره­قات برای هر خانوار به‌طور متوسط 6078 هزار ریال بود.

چکیده [English]

The main objective of this research is to study the production of Ribes biberistentii (reddish blackberry) and its role in rural household`s economies of the Arasbaran region. This research was carried out using library references and field surveys in the summer of 2018 in the Arasbaran forests. A questionnaire was used to collect data on socio-economic from 32 harvesters of Kalasur village in Ilgeneh chay watershed of Arasbaran. The collected data were about fruit price, type and method of processing, amount of harvest and consumption of raw and processed fruit, sales and marketing, and medicinal uses. Pearson correlation analysis was performed between different tree characteristics and fruit production. The results showed that the weight of 1000 fruit of reddish blackberry was 240 grams. Fruit production of this species had the highest and positive correlation with the average crown diameter (0.767) at 0.01 significant level. The results showed that its fruit had medicinal uses to treat high blood pressure by local peoples. Concerning the price of raw fruit and the amount of harvest, the economic value of fruit harvested for the entire households was 192 million rials at 2017. The average annual economic value of harvesting and selling of reddish blackberry for each household was about 6078 thousand rials.
