Rates of harvest damage in various vegetable crops has been linked to soil water content at harvest and the resulting cell turgor. Casual observation in sugar beet suggests that rates of surface cracking at harvest are similarly linked to soil water content. The rates of damage during harvest and handling of sugar beet has also been linked to their...

Soilless cultivation of vegetables with digestate fertilizer from biogas production as a nutrient source is a promising method for integrating food production and organic waste management. In this study, bok choy (Brassica rapa var. chinensis) was cultivated in a hydroponic nutrient film technique system with biogas digestate as the only fertilizer...

Artificial light is used for many horticultural crops produced in greenhouses, not least ornamental pot plants. New technologies such as LEDs will possibly replace high intensity discharge lamps as the main technology for lighting in horticulture. However, LEDs are quite different from discharge lamps as regards the handling of waste heat. They hav...

In this study, the green microalga Chlorella vulgaris was exposed to monochromatic light at six different wavelengths in order to study the effect on biomass productivity and fatty acid content. A significantly higher amount of biomass by produced in the treatments with yellow, red and white light compared with blue, green and purple light. There w...

This study investigated the effects of pH and nitrogen form and concentration on cadmium (Cd) uptake by potato (Solanum tuberosum L.) grown in hydroponic culture. Potato plants grown for 10 d in pH-buffered nutrient solution were exposed for 24 h to 25 nM CdCl2 labelled with 109Cd. Plants showed a significantly higher Cd uptake and accumulation at...
Article
The effect of different levels and forms of nitrogen (N) fertilizer on cadmium (Cd) concentrations in potato (Solanum tuberosum L.) tubers, a large component of the northern European diet, was investigated with the aim of decreasing the Cd content. A high and a low Cd-accumulating cultivar were used in two field trials and a pot experiment. The N f...

In order to test the potential effect of prior exposure to different Cd concentrations on Cd uptake and accumulation, plants of Arabidopsis thaliana, including a phytochelatin‐deficient mutant, cad1‐3, and the wild type, were compared. For Cd uptake experiments, plants were grown for 1 week in nutrient solution containing different Cd concentration...

Plants are most often exposed to multiple environmental stress, rather than single stress phenomena. Therefore, the aim of this study was to investigate plant response to two potential stress factors. We also wished to determine whether one of the stress factors would be dominant, and to assess the outcome in terms of the importance for plant survi...

The possible interaction of two stresses, UV-B radiation and cadmium, applied simultaneously, was investigated in Brassica napus L. cv. Paroll with respect to chlorophyll fluorescence, growth and uptake of selected elements. Plants were grown in nutrient solution containing CdCl2, (0, 0.5, 2 or 5 μM) and irradiated with photosynthetically active ra...
