Effect of aqueous leaf extracts of 8 allelopathic tree species viz., Accacia nilotica (L.) Willd ex Del., Alstonia scholaris (L.) R. Br., Azadirachta indica (L.) A. Juss., Eucalyptus citriodora Hook, Ficus bengalensis L., Mangifera indica L., Melia azedarach L. and Syzygium cumini (L.) Skeels was studied on germination and seed-borne mycoflora of wheat (Triticum aestivum L.). Wheat seeds were s...
Safflower (Carthamus tinctorius L.) is one of the multi-purpose oilseed crops which has a high adaptation to different conditions such as resistance to drought and it is suited to be grown in arid and semi-arid regions such as Isfahan province. Root rot disease is an important soil-borne disease of safflower in Isfahan, which can be caused by different pathogens. The objective of this study was...
We investigated the sexual reproductive mode of the two most important etiological agents of soybean sudden death syndrome, Fusarium tucumaniae and Fusarium virguliforme. F. tucumaniae sexual crosses often were highly fertile, making it possible to assign mating type and assess female fertility in 24 South American isolates. These crosses produced red perithecia and oblong-elliptical ascospores...
This paper reported on the various filamentous fungi strains that were isolated from a wild grown Catharanthus roseus. Based on the morphological characteristics and molecular technique through a Polymerase Chain Reaction and DNA sequencing method using internal transcribed spacer (ITS), these fungi had been identified as a Colletotrichum sp., Macrophomina phaseolina, Nigrospora sphaerica and F...
در این پژوهش زوال گیاهان زینتی از نظر آلودگی به عوامل بیماریزای قارچی و شبهقارچی بررسی گردید. نمونهبرداری طی سالهای 1390 و 1391، از گیاهان بیمار در مناطق مختلف و گلخانههای شهر شیرازکه علائم پژمردگی، پوسیدگی ریشه و طوقه داشتند انجام گرفت. در بین این عوامل، Fusarium solani، F. oxysporum، F. equiseti، F. culmorum، F....
Diseased fibrous roots of blighted citrus trees were collected from 12 locations throughout the Central Florida citrus growing area. Sixty-five isolates of Fusarium solani (Mart.) Appel & Wr. emend. Snyd. & Hans, cultured from these roots were examined for their ability to produce phytotoxic compounds. When grown as shake cultures on a mineral salts-glucose medium with NH4NO3 as the N source, a...
Abstract Background Pathogenicity of entomopathogenic fungi (EPF) depends mainly on their ability to produce efficient enzymes, which degrade insect’s integument and other cellular components. Lipases are the first enzymes secreted by these fungi, then proteases, phospholipases, chitinases. Results Twenty-six fungal strains, isolated from aphids, Aphis sp., Linnaeus (Homoptera, Aphididae), toma...
گل ها و گیاهان زینتی، نه تنها در محیط های خارج از محل زندگی بلکه در داخل محیط های مسکونی نیز از اهمیت ویژه ای برخوردارند. همچنین در سال های اخیر صادرات گل و گیاهان زینتی زمینه های بسیار مناسبی را در امر کارآفرینی و ارزآوری فراهم کرده است. از طرفی بیماری پژمردگی این گیاهان و پوسیدگی ریشه و طوقه آن ها سال هاست که به طور گسترده در شهرستان شیراز وجود دارد، لذا به-دلیل اهمیت این گیاهان و نگهداری منا...
