Changes of EUF-extractable nitrogen (N) (nitrate, ammonium, organic N) in 20 arable bare soils, subsequently planted with ryegrass (Lolium multiflorum L.) and cutting three times were investigated in pot experiments. All 20 soils responded qualitativ

The relationship between the apoplastic pH in young sunflower roots (Helianthus annuus L.) and the plasmalemma ferric chelate reductase (FC-R; EC 1.16.1.7) activity in roots was investigated. The hypothesis was tested that a high apoplastic pH depres

It is generally accepted that soil microorganisms play an important role in producing siderophores which enhance the availability of soil Fe to higher plants. There is not much direct experimental evidence to support this supposition, however, becaus

The hypothesis of this investigation is that a substantial proportion of nitrogen (N) released by roots of entire plants into the soil are amino acids which are transported from upper plant parts to roots via phloem and from the phloem released into

High concentrations of Fe in the roots of plants grown in calcareous soil have been found in a variety of plants, which, nevertheless, show Fe deficiency symptoms. In the present work, energy dispersive X-ray (EDX) analysis at the cellular level has

The main objective of the present work was to clarify the causal relationship between leaf apoplastic pH increase and Fe chlorosis under alkaline growth conditions. It has been shown that nitrate supply in contrast to ammonium supply induced a pH inc

It is well known from earlier work that water stress and salinity results in depressed plant growth and high fruit quality of tomato (e.g. increased sugar and acid levels), but generally is associated with a low marketable fruit yield. In the present

It has been hypothesized that under NO3 − nutrition a high apoplastic pH in leaves depresses Fe3+ reductase activity and thus the subsequent Fe2+ transport across the plasmalemma, inducing Fe chlorosis. The apoplastic pH in young green leaves of su

A fluorimetric ratio technique was elaborated to measure apoplastic pH in the outer root cortex of maize (Zea mays L.) grown hydroponically. A newly synthesized fluorescent probe, fluorescein boronic acid (pK(a) = 5.48), which covalently binds to the

The objective of the investigation was to identify the most important organic N-containing fractions extracted from soils by electroultrafiltration (EUF) or a CaCl2 solution, respectively, and their importance for nitrogen mineralization. The investi
