Changes in radiocaesium uptake and distribution in wheat during plant development: a solution culture study
Spring wheat plants were grown in a 137Cs labelled nutrient solution, either in the presence or absence of NH4 as a secondary N source. Between 11 and 64 days after sowing (DAS), plants wereExpand
Effect of external potassium supply and plant age on the uptake of radiocaesium (137Cs) by broad bean (Vicia faba): interpretation of results from a large-scale hydroponic study
Abstract Experimental results are presented from a 60 day hydroponic experiment which investigated the simultaneous effects of potassium concentration in solution and plant age on both potassium andExpand
Effects of external potassium supply on compartmentation and flux characteristics of radiocaesium in intact spring wheat roots
TLDR
Results obtained in this study suggested that the inhibitory effect of potassium on the net uptake of radiocaesium by the plant root may be partially ascribed to the fact that at higher external potassium concentrations Cs + efflux rates were much higher. Expand
The biology of mycorrhiza in the Ericaceae: XVII. The role of mycorrhizal infection in the regulation of iron uptake by ericaceous plants.
TLDR
The role of the ericoid mycorrhizal endophyte Hymenoscyphus ericae (Read) Korf & Kernan in the regulation of iron uptake by ericaceous plants is investigated and the involvement of a hydroxamate siderophore in the absorption of Fe by M plants at low [Fe]ext is suggested. Expand
Effect of potassium starvation on the uptake of radiocaesium by spring wheat (Triticum aestivum cv. Tonic)
Short term experiments were carried out to investigate the effect of internal tissue potassium concentration on the uptake of radiocaesium by spring wheat (Triticum aestivum cv. Tonic). The resultsExpand
Effect of potassium (K) supply on the uptake of 137Cs by spring wheat (Triticum aestivum cv. Tonic): a lysimeter study
TLDR
Results showed that the uptake of radiocaesium by spring wheat was reduced by the addition of potassium, but this inhibitory effect was less marked at later stages of plant growth due to factors such as the spatial variability of potassium within the soil. Expand
The biology of mycorrhiza in the Ericaceae XVI. Mycorrhiza and iron uptake in Calluna vulgaris (L.) Hull in the presence of two calcium salts.
TLDR
The nutritional implications of the results are explored, special emphasis being placed upon the possible role of mycorrhizal infection in soils of high calcium content and in situations where iron is present in sparingly soluble mineral combination with,phosphates. Expand
The biology of mycorrhiza in the Ericaceae. XIV. Effects of iron and aluminium on the activity of acid phosphatase in the ericoid endophyte Hymenoscyphus ericae (Read) Korf and Kernan
TLDR
L'endophyte en culture pure est traite avec des concentrations variables en Fe 2+ , Al 3+ et P. inorganique dans l'alimentation phosphoree des Ericaceae dans des ecosystemes naturels. Expand
The effect of spray volume on spray partitioning between plant and soil
Applications of chlorsulfuron (11.25 g ai ha-1) were made to wheat, flax, canola and lentils at spray volumes of 48, 108 and 217 1 ha-1, and with metsulfuron methyl (6.00 g ai ha-1) at spray volumesExpand
