شبهگونههای تریکودرما از مهمترین آنتاگونیستهای قارچهای بیمارگر گیاهی میباشند که شناسایی و تعیین توان آنتاگونیستی آنها کمک زیادی به مطالعات کنترل زیستی میکند. هدف اصلی از این مطالعه تعیین توان کنترلزیستی جدایههای بومی تریکودرما، جدا شده از مزارع چغندرقند، علیه گونههای phytophthora drechleri و p. cryptogea عوامل پوسیدگی ریشه چغندرقند میباشد. طی دو فصل زراعی (1386 و 1387)، 85 جدایه از گو...
Differential sensitivities to the cell wall stress caused by Congo red (CR) have been observed in many fungal species. In this study, tolerances and CR was studied with an assorted collection of species from three phylogenetic classes: Sordariomycetes, Dothideomycetes, Eurotiomycetes, orders, eight families. These grouped into different ecological niches, such as insect pathogens, plant saprotr...
Fifteen fungal and three bacterial biological control agents (F-BCA B-BCA, respectively) were isolated from the canola production areas of Western Australia to investigate their potential for controlling sclerotinia stem rot (SSR) caused by Sclerotinia sclerotiorum under in vitro field conditions. The capacity these isolates inhibit mycelial growth sclerotia formation S. was assessed dual cultu...
Towards assessing the biodiversity and biogeography of Trichoderma, we have analyzed the occurrence of Trichoderma species in soil and litter from four areas in China: North (Hebei province), South-East (Zhejiang province), West (Himalayan, Tibet) and South-West (Yunnan province). One hundred and thirty five isolates were grouped according to tentative morphological identification. A representa...
Trichoderma spp., which widely exist in nature, are always used as plant growth-promoting stimulants. However, there is little reporting about the combined use of strains to promote growth plants. We explored two different (Trichoderma atroviride LX-7 and citrinoviride HT-1) a mixture on effects pakchoi. In this study, vitro-promoting traits were determined, six treatments used: T. LX-7, HT-1, ...
