Regen-eration was carried out by rinsing the cation-and anion IER bags several times in 4% HC1 or 3% ... The latter is true eg for Scots pine (Arnold, 1992; Boxman and Roelofs, 1988), Douglas fir (Gijsman, 1991; Kamminga-Van Wijk, 1993) and Norway spruce (Ingestad, 1979 ...

In areas where metal contaminated soils are used for food crop production, metals relatively mobile within the plant, such as cadmium (Cd) and zinc (Zn) can easily come into the food chain with great risks for human health. Since bioavailability of heavy metals in soils varies with soil and plant characteristics, e.g., mineralogical and organic matter properties of the soil and plant metal susceptibility, prediction of heavy metal uptake by plants by the common soil and plant chemical analysis techniques is often unreliable. Recently, the use of biomarkers has been suggested to be a suitable technique complementing chemical soil analysis. Therefore, the usefulness of the biomarker phytochelatin (PC), a non‐protein thiol, specifically induced in plants suffering from heavy metal stress, was tested. Maize (Zea mays L.) plants were exposed to excess copper (Cu) or Cd in nutrient solution sy...

We aimed to assess the short- and long-term effects of a wide range of N inputs, and of grazing versus mowing, on net CH4 emissions of grasslands in the Netherlands. These grasslands are mostly intensively managed with a total

We varied tissue N concentration by supplying N at different rates by adding nitrate in different, exponentially increasing amounts to the nutrient solution on which the tomato plants were grown.

Plants with varying nitrogen availability were grown by adding N daily in exponentially increasing amounts to a nutrient solution at different rates. Leaves of plants grown at low nitrogen availability had a high leaf C/N ratio

Tomato plants (Lycopersicon esculentum) were grown at six levels of nitrogen availability. When nitrogen availability increased, plant relative growth rate increased, but tissue carbon/nitrogen ratio in the second oldest true leaf and
