چکیده
Some ۳۵۰ Trichoderma isolates were obtained from soil samples collected from different parts of Iran. Cultures were purified on ۲% water agar by hyphal tip method prior to identification. Obtained isolates were identified using morphological features including colony characters (pigmentation and growth rate on PDA) and microscopic characters such as shape of conidiophores, shape and size of conidia and phialides. Microscopic features of conidiophores and shape and size of conidia were studied and recorded ۳–۵ days after inoculation on cultures grown on ۲% MEA at ۲۰°C under ambient laboratory conditions by using light microscopy and scanning electron microscopy (SEM). Ten species including T. citrinoviride, T. longibrachiatum, T. saturnisporum, T. hamatum, T. harzianum, T. inhamalum, T. tomentosum, T. virens, T. asperellum and T. koningii were already identified and reported from Iran (ZAFARI et al. ۲۰۰۲) and three new species, T. ghanense (Fig. ۱), T. spirale (Fig. ۲) and T. atroviride (Fig. ۳) from sections Longibrachiatum, Pachybasium and Trichoderma, respectively, are reported here. Trichoderma atroviride is known as one of the most important biocontrol agents against plant diseases caused by some pathogenic fungi.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
