Pseudomonas aeruginosa produces, under conditions of iron limitation, a high-affinity siderophore, pyoverdine (PVD), which is recognized at the level of the outer membrane by a specific TonB-dependent receptor, FpvA. So far, for P. aeruginosa, three different PVDs, differing in their peptide chain, have been described (types I-III), but only the FpvA receptor for type I is known. Two PVD-produc...
Adventitious root formation in stem cuttings is affected by exogenous and endogenous factors. The study assessed the effect of Fe(III)-EDDHA (ethylenediamine-N,N-bis 2-hydroxyphenyl acetic acid) on rooting 4 indol-3-butyric acid (IBA)-treated hardwood aromatic medicinal species Rosmarinus officinalis. Cuttings treated with 0, 1000, 2000 or 3000 mg L?1 IBA were placed pots filled sand:perlite mi...
یکی از مهم‌ترین معضلات کشت ناترک در استان خوزستان بیماریهای پوسیدگی طوقه و ریشه میباشد. عمدهترین عامل بیماری در این استان قارچ Fusarium solani است. در گلخانه ضمن مطالعه بیماری‌زایی قارچ F. solani روی ناترک، اثرات سطوح مختلف pH (8 و 6)، کلات کننده EDDHA (صفر، 10 و 20 میلیمول در لیتر) و کلسیم (صفر و 12 میلی اکیوالان بر لیتر) روی صفات مختلف (میانگین وزن خشک و تر بخش هوایی گیاه، وزن تر ریشه و ...
This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...
in vitro propagation of az x m9 new apple rootstock resulted of breeding program of vegetative apple rootstock in iran was investigated. nodal explants were inoculated in murashige and skoog (ms) medium supplemented with various concentrations of 6-benzylaminon purine (bap) (0.4, 0.8 and 1.2 mg/l) alone or with naphthalene acetic acid (naa) (0.1 mg/l). we examined the effect of different concen...
Nutrition management in growth season has a main effect on production and accumulation of secondary metabolites in grapevine berries. In this research the effects of foliar application of potassium sulfate (K; 0, 1.5, and 3%) and iron chelate (Fe; 0, 0.5, and 1%) on accumulation of resveratrol and viniferin and antioxidant capacity of ‘Bidaneh Sefid’ grape berries was evaluated. This study was ...
In order to determine the best source of iron fertilizer for green pepper under alkaline conditions, the experiment was conducted as factorial with three factors include of iron fertilizer (control, Fe-EDDHA and nano iron chelate), sodium bicarbonate (0 and 10 mM) and two cultivars (Bonanza and Griffaton) with three replications. Plants were treated with bicarbonate 45 days after planting for 2...
پایه های رویشی پسته قزوینی و ucb-1 از ارقام شناختهشده در دنیا هستند که به لحاظ سازگاری به خشکی و شوری (قزوینی) و سرما و بیماری های ورتیسلیومی (ucb-1) دارای اهمیت هستند. به منظور بهبود کیفیت رشد رویشی و میزان ساقه زایی و همچنین افزایش راندمان ریشه زایی، اثر اسکوپولتین و منبع آهن (fe-eddha و fe-edta) همراه با پژوهش تغییرات فعالیت آنزیم پراکسیداز بررسیشد. همچنین بررسی خصوصیت های کینتیک با استفاد...
