پوسیدگی طوقه و ریشه از مهمترین بیماریهای کدوییان در جهان است. جهت شناسایی عوامل قارچی مولد این بیماری در سال زراعی 90-1389 از مزارع محصولات جالیزی (هندوانه، خربزه و طالبی) در منطقه شاهرود، میامی و بیارجمند بازدید و نمونههای مشکوک به بیماری پوسیدگی طوقه و ریشه جمعآوری و به آزمایشگاه منتقل شدند. قطعات بافتهای آلوده پس از ضدعفونی سطحی با هیپوکلرید سدیم 1 درصد روی محیط کشت PDA و یا بدون ضدعفون...
Rhizoctonia solani is a plant pathogenic fungus that causes significant establishment and yield losses to several important food crops globally. This is the first application of high resolution X-ray micro Computed Tomography (X-ray μCT) and real-time PCR to study host-pathogen interactions in situ and elucidate the mechanism of Rhizoctonia damping-off disease over a 6-day period caused by R. s...
Rhizoctonia solani is a causative agent of sheath blight, which results in huge economic losses every year. During its life cycle, the formation of sclerotia helps Rhizoctonia solani withstand a variety of unfavorable factors. Oxidative stress is a key factor that induces sclerotium formation. The differentiated and undifferentiated phenotypes of R. solani AG-1-IA were obtained by controlling a...
The effects of six species of phytopathogenic fungi mycelia as elicitors on trichodermin yield by Trichoderma brevicompactum were investigated. Neither nonviable nor viable mycelia of Botrytis cinerea, Alternaria solani, Colletotrichum lindemuthianum, and Thanatephorus cucumeris demonstrated any elicitation on the accumulation of trichodermin. However, the production of trichodermin was increas...
damping off caused by rhizoctonia solani (isolate ag4) constrains growing soybean in the north iranian province of golestan. the pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. the response of soybean cv. williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. on mal...
نماتد مرکبات، Tylenchulus semipenetrans، دارای گسترش جهانی بوده و یکی از عوامل سرخشکیدگی در باغهای مرکبات محسوب میشود. آلودگی توأم نماتد و قارچهای بیمارگر، تأثیر مضاعفی بر رشد گیاه میگذارد. بهمنظور بررسی اثر اکتینومیستها در کنترل نماتد و بیمارگرهای ثانویه، تعداد 30 نمونه خاک آلوده از فراریشه مرکبات شرق استان گیلان و غرب استان مازندران جمعآوری شدند. در نتیجه20 جدایه اکتینومیست با استفاده...
some types of faba bean suspected of root pathogens in lorestan provincec, iran were sampled during years 2007 to 2008. after some pathogenicity tests, 121 samples which suffered from root fungus disease and from chromista were totally isolated. the abundance of fungi, fusarium solani, which caused the faba bean root rot was more than that of the other separated types and as well as the farming...
تأثیر ضد قارچی عصاره های مختلف 23 آرایه بریوفیت شامل 21 گونه خزه و دو گونه هپاتیک (جگرواش) برای نخستین بار در کشور صورت گرفت. بدین منظور، تأثیر عصاره های هر یک از گونه های مورد نظر روی هفت گونه قارچ بیماریزای گیاهی به اسامی:alternaria alternata, f. oxysporum, fusarium solani, macrophomina phaseolina, pythium sp., rhizoctonia solani, وverticillium dahliae بررسی گردید. جهت انجام این کار، ابتدا ن...
ABSTRACT In Mexico, Creole corn has presented problems related to seed rot. Therefore, the objective of this study was determine frequency fungi associated with seeds. From January February 2019, 13 samples were collected from several localities in Guerrero, Mexico. The processed PDA culture medium and each fungus estimated based on cultural characteristics taxonomic keys. Considering symptomat...
