چکیده
فندق به عنوان یکی از مهمترین میوه‌های خشکباری حاوی مجموعه با ارزشی از آنتی­ اکسیدان­ها و مواد مغذی است. کیفیت مغز فندق به شدت تحت تأثیر ترکیبات آن قرار دارد. ظرفیت آنتی­اکسیدانی و ترکیبات بیوشیمیایی مغز فندق بیشتر به رقم، شرایط اقلیمی و اثر متقابل شرایط آب و هوایی و ژنوتیپ بستگی دارد. مطالعه حاضر، به منظور بررسی خصوصیات کیفی از جمله میزان ویتامین ث، فعالیت آنتی­ اکسیدانی، فنل کل، فلاونوئید کل و عناصر معدنی در 11 رقم و ژنوتیپ شامل هفت رقم وارداتی به نام­های روند دوپیمونت، نگرت، سگورب، سیوری، مورفینسکی، فرتیل دکوتارد، سوچی، و چهار ژنوتیپ بومی به نام‌های اشکور1، اشکور2، اشکور3 و اشکور4 در منطقه اشکورات رودسر در سال 1396 انجام شد. نتایج تجزیه واریانس داده‌ها نشان داد در کلیه صفات مورد مطالعه در بین ارقام و ژنوتیپ‌های فندق اختلاف معنی­داری (P≤0. 01) وجود دارد که این امر نشان دهنده تنوع ژنتیکی بالا در بین ارقام و ژنوتیپ­های مورد مطالعه است. تجزیه همبستگی صفات نشان دهنده وجود ارتباط مثبت و منفی معنی­داری در برخی از صفات مهم بود. با توجه به دندروگرام حاصل از تجزیه خوشه­ای به روش "وارد"، در فاصله اقلیدسی 27، ارقام و ژنوتیپ­های فندق در چهار خوشه اصلی دسته بندی شدند.

چکیده English

As one of the most important nuts, hazelnut (Corylus avellana L. ) contain a valuable set of antioxidants and nutrients. The quality of hazelnut kernel was strongly affected by kernel compounds. The antioxidant capacity and biochemical compounds depends more on the cultivar, climatic conditions and the interaction between climatic conditions and genotypes. The present study was conducted to determine the quality properties including vitamin C, antioxidant activity, total phenol, flavonoid and mineral element in 11 cultivars and genotypes included seven imported cultivars (Ronde dupimont, Negreta, Segorbe, Sivri, Morfineski, Fertile decotard and Sochi), and four local Iranian genotypes (Eshkevar1, Eshkevar2, Eshkevar3 and Eshkevar 4) in the Rudsar Eshkevarat region in 2017. Analysis of variance results were showed that there was significant difference (P≤0. 01) among examined cultivars for all characters and showed high genetic variation in all of the studied cultivars. Correlation analysis showed the existence of significant positive and negative correlation among some important traits. According to the cluster analysis dendrogram performed by "Ward" method, cultivar and genotypes of hazelnut in Euclidian distance 27 were classified into four clusters.
