چکیده
به منظور بررسی قارچ های همراه بذر لاین مادری (لاینAS9) سورگوم هیبرید رقم اسپیدفید در مزارع تولید بذر در استان خراسان رضوی، مطالعات بیماری شناسی بذر روی تعداد 30 نمونه متعلق به دو سال زراعی 1383-1381 انجام شد. جداسازی و مطالعه قارچ های بذرزاد (به جز عوامل سیاهک ها) با روش های بلاتر معمولی، بلاتر انجمادی و پلیت آگار انجام و قارچ های Fusariumverticillioides, Bipolarissorghicola, Cladosporium sp., Alternariaspp., Penicillium spp. و Cephalosporiumacremonium به ترتیب در 0/5، 4/5، 16، 19/25، 21 و 0/75 درصد بذور شناسایی شدند. در روش شستشوی بذر و مطالعه میکروسکوپی تلیوسپورهای عامل سیاهک های بذرزاد، تلیوسپورهای قارچ های Sphecelothecacruenta و Sporisoriumsorghi به تعداد 12 و 42 تلیوسپور در کیلوگرم بذر ردیابی شدند.
