Kahlschlagbedingte Veränderungen im Wurzelraum eines Buchenniederwaldes auf Rendzinawiss Jura (Basel-Land) on a clearcut stand of 19 a. Selected observations like beech root vitality and contents of soil water and soil elements in stand compared to the cleartcut area are presented in this paper. After one year of tree removal, soil water contents on the clearcut area were significa

Der Einfluß von Bodenbearbeitung und N-Düngung auf die Verteilung von 14C-markierten Assimilaten aufo respond to nutrient limiting conditions. Estimation of rhizodeposition for field-grown oilseed-rape plants (. L.) using .C-pulse labelling technique was the objective of our present work. Treatments consisted of two soil tillage systems (ploughing/surface tillage, ‘Horsch’) and two N rates (0 and

Verhältnis von Sproß und Wurzel bei der Expression von Genen der Sulfatassimilation in ,ides for the first time the possibility to analyse the expression patterns of almost all the genes of sulfate assimilation and cysteine biosynthesis in plants. Thus the troublesome assay of the notoriously low activities and labile enzymes of the pathway is avoided. Quantification of steady-state mR

H. B. K. (Pfirsichpalme): Besonderheiten der Morphologie und Anatomie der Wurzelns. Despite the low nutrient availability in most tropical soils biomass production of . is high. It must be assumed that . has a high nutrient acquisition efficiency. The morphology and anatomy of the roots of . were examined here as these parameters may play an important role in nutrient acquisitio

C- und N-Verbindungen aus Bioabfallkomposten und ihre Bedeutung für die N-Nachlieferungential of N immobilization in soil with repeated biowaste compost application was lower as that of the soil with mineral N fertilization. These results show that a repeated biowaste compost fertilization has a quantitative and qualitative influence on the N mineralization potential of soils.

Frühe physiologische Reaktionen zur NH,,-ausgelösten Toxizität — eine vergleichende Untersuchung zwiectively. From these results we conclude that in maize prolonged reduction of the tonoplast H. gradient may play an important role in ammonium toxicity. In rice, this reduction is still smaller as rice effectively restored raised vacuolar .H under conditions of increased NH. permeation into the vacuole (... 1998).
