During the study on endophytic fungi of stone fruits including apricot, peach and nectarine in W Azarbaijan (NW Iran), a large number of isolates with Alternaria characteristics were isolated from different parts of these plants and studied taxonomically. Isolation was made based on endophytic fungal isolation method and following surface sterilization procedure. From 100 different plant samples, 102 isolates with Alternaria characteristics were obtained. Based on morphological characteristics, 10 species viz. Alternaria  alternata, A. arborescens, A. atra, A. consortialis, A. destruens, A. dumosa, A. infectoria, A. japonica, A. pseudorostrata, and A. tenuissima were identified. Alternaria tenuissima, A. alternata and A. arborescens with 30, 25 and 16 isolate had the highest frequency respectively. All the identified species were isolated for the first time as endophytic fungi from apricot, peach and nectarine worldwide. Alternaria consortialis and A. pseudorostrata are new to mycoflora of Iran.

Abstract [Persian]

در مطالعه انجام گرفته روی قارچ‌های اندوفیت درختان میوه هسته‌دار شامل زردآلو، هلو و شلیل در استان آذربایجان غربی، تعداد قابل توجهی از جدایه‌های جنس Alternaria از بخش‌های مختلف این درختان جداسازی شده و مورد مطالعه تاکسونومیکی قرار گرفتند. عمل جداسازی قارچ‌های اندوفیت مطابق با روش جداسازی این قارچ‌ها و طی روند ضد عفونی سطحی چند مرحله‌ای انجام گرفت. از تعداد 100 نمونه گیاهی مورد بررسی، تعداد 102 جدایه قارچی متعلق به جنس Alternaria جداسازی شد. براساس مطالعات ریخت‌شناختی،10 گونه شامل: Alternaria alternata، A. arborescens، A. atra، A. consortialis، A. destruens، A. dumosa،A. infectoria، A. japonica، A. pseudorostrata و A. tenuissima شناسایی شدند. گونه‌های A. tenuissima، A. alternata وA. arborescens به ترتیب با 30، 25 و 16 جدایه بیشترین فراوانی را در میان گونه‌های شناسایی شده به خود اختصاص دادند. تمامی گونه‌های شناسایی شده برای نخستین بار به عنوان قارچ‌های اندوفیت از درختان زردآلو، هلو و شلیل در دنیا و گونه‌هایA. consortialis و A. pseudorostrata به عنوان گونه‌های جدید برای فلور قارچی ایران گزارش می‌شوند.
