| 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. | ||

| چکیده [English] | ||
| Mycoflora of hybrid sorghum seeds in line production areas of Khorasan Razavi Seed health analysis was carried out on 30 Sorghum bicolor cv. speed feed(line AS9) seed samples belonging to two growing seasons (2001-2004) which were routinely submitted by Feizabad Research Center, Khorasan Razavi provience to Seed and Plant Certification and Registration Institute, Iran. Applying simple blotter-, deep freezing blotter-, and agar plate- methods for detection of seedborne mycoflora revealed the presence of Fusarium verticilloides, Bipolaris sorghicola, Cladosporium sp., Alternaria sp., Penicillium spp.,and Cephalosporium acremonium in seed samples at the rates of 0.5, 4.5, 16, 19.25, 21 and 0.75 percent, respectively. Using washing test, teliospores of Sphacelotheca cruenta and Sporisorium sorghi at the rates of 12 and 42 teliospores/Kg seed were detectedon the basis of teliospore morphology. | ||
