آهن یکی از عناصر ضروری برای رشد گیاه میباشد که در بسیاری از فرایندهای گیاه از جمله فعال کردن آنزیمهای دخیل در انتقال الکترون فتوسنتزی و میتوکندری نقش دارد. در این آزمایش به منظور بررسی و مقایسه اثر منابع مختلف آهن بر عملکرد و خصوصیات فیزیولوژیکی دو رقم کاهو در سیستم هیدروپونیک (لایه نازک محلول غذایی nft) آزمایشی به صورت فاکتوریل و در قالب طرح کاملاً تصادفی اجرا شد. فاکتورها شامل ارقام کاهو (ش...
Bu çalışmada, sera koşullarında ekmeklik ve makarnalık buğday çeşitlerine farklı Fe form (FeSO4.7H2O; Fe-EDTA; Fe-EDDHA) uygulama şekillerinin (toprak, yaprak toprak+yaprak) tane konsantrasyonuna olan etkisi araştırılmıştır. Elde edilen sonuçlara göre; topraktan (0 5 mg kg-1), yapraktan (%0.2 Fe) , toprak + kg-1 %0.2 yaprak) formu (özellikle Fe-EDTA FeSO4) uygulamalarının çeşitlerinin kuru madd...
به منظور تعیین بهترین منابع آهن برای گیاه فلفل دلمه ای در شرایط قلیایی و غیر قلیایی، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با سه فاکتور نوع کود آهن در سه سطح (شاهد (بدون آهن)، نانو کلات آهن و fe-eddha) و بیکربنات سدیم در دو سطح (صفر و 10 میلی مولار) و رقم (بنانزا و گریفاتون) در سه تکرار اجرا شد. گیاهان پس از 45 روز رشد در محیط کشت بدون خاک به مدت 2 ماه تحت تیمار بیکربنات سدیم قرار...
In response to tackling the environmental consequences of fertiliser production, biofertilisers from organic sources are strongly promoted in line with circular economy and maximising resource use. Despite outstanding potential bio-based fertilisers for sustainable development agricultural sector, an investigation these is required replace synthesised fertilisers. Considering importance iron as...
In order to investigate the effect of different iron (Fe) sources on lettuce yield, under the sodium bicarbonate stress conditions, a greenhouse experiment was carried out with two factors including Fe source in three forms (Fe-EDDHA, Fe nano chelate and nanofertile) and sodium bicarbonate at three levels (0, 5, and 10 mM) with three replications. Three weeks after transplanting, seedlings were...
Iron is an essential element for plant growth which is involved in many plant processes such as photosynthesis and activating enzymes involved in mitochondrial and photosynthetic electron transfer. In order to compare the effect of different sources of iron on yield and physiological characteristics of two varieties of lettuce in hydroponic culture, a complete random factorial experiment was do...
Abstract Due to the increase in horticultural production intensive techniques are needed. These generate soil degradation, since natural recovery time between crops is insufficient. The usual way solve this problem use of fertilizers, as they effective short available. Conventional fertilizers highly soluble salts, allowing their absorption by plant roots. However, dumped on soils more quantity...
Substrate grown roses appear to be susceptible to chlorosis, which indicates problems with Fe or Mn uptake and hence yield reduction. In common practice this problem is often treated by the addition of extra Fe-chelate, or the use of Fe-EDDHA instead of Fe-DTPA. In previous tests, it was shown that the pH in the root environment is a major factor in the prevention of chlorosis. Moreover, the ap...
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...
