كمك به شناسايي گونه‌هاي Pseudocercospora در ايران

CONTRIBUTION TO THE IDENTIFICATION OF Pseudocercospora SPECIES IN IRAN

به منظور شناسايي گونه هاي جنس Pseudocercospora نمونه‌برداري از مناطق مختلف استان هاي شمالي كشور در طول تابستان و پاييز سال 1389 انجام شد. علاوه بر اين نمونه هاي موجود در مجموعه قارچ هاي وزارت جهاد كشاورزي واقع در موسسه تحقيقات گياه پزشكي كشور نيز مورد بازبيني قرار گرفتند. گونه هاي Pseudocercospora atromarginalis (روي Solanum nigrum)، P. cruenta (روي Vigna sinensis)، P. griseola (روي Phaseolus vulgaris)، P. heteromalla (روي Rubus sp.)، P. kaki (روي Diospyros lotus D. kaki)، P. punicae (روي Punica granatum)، P. salicina (روي Salix alba) و P. vitis (روي Vitis sylvestris) شناسايي شدند. از بين اين گونه ها، P. heteromalla و P. salicina براي اولين‌بار از ايران گزارش مي شوند. هم‌چنين نام Phaeoisariopsis griseola به Pseudocercospora griseola تغيير يافت. نام ساير گونه ها در فهرست قارچ هاي ايران آمده است.

Eight collections of Pseudocercospora species from different localities in Northern provinces of Iran were obtained and examined during Summer-Autumn of 2010. Furthermore all of specimens belonging to the genus Pseudocercospora deposited in fungal collection of Ministry of Jihad-e-Agriculture in Iranian Research Institute of Plant Protection were re-examined. Eight species on nine host plants were identified including: Pseudocercospora atromarginalis (on Solanum nigrum), P. cruenta (on Vigna sinensis), P. griseola (on Phaseolus vulgaris), P. heteromalla (on Rubus sp.), P. kaki (on Diospyros lotus, D. kaki), P. punicae (on Punica granatum), P. salicina (on Salix alba), P. vitis (on Vitis sylvestris). Among these, P. heteromalla and P. salicina are new records for mycobiota of Iran. The name of Phaeoisariopsis griseola changed into Pseudocercospora griseola.Other species were already been reported from Iran.
