摘要:
Effect of the heavy metals chromium, nickel, copper, zinc, cadmium, mercury and lead on uptake and translocation of K and P by young barley plantsThe uptake of potassium and phosphate into the roots and shoots of 7 days old barley plants from double‐labelled (42K,32P) nutrient solutions containing chromium, nickel, copper, zinc, cadmium, mercury or lead (10−6‐ 10−4moles/1) was measured in a constant environment after 5 hours, in order to compare early stages of toxicity.K and P uptake and translocation were inhibited by the 7 heavy metals to a different extent; K was more affected than P, and translocation of both nutrients into the shoots was more inhibited than uptake into the roots. Plants showed no visible injuries.Mercury had by far the greatest effect, zinc was almost ineffective: K uptake e.g. was reduced to 21% of the control by 10−4moles Hg/l, but only to 97% by the same amount of Zn, and P translocation was reduced to 8% by Hg, but was not affected by Zn. The least significant effect of Hg was detectable at a concentration of 4.10−7moles Hg/l ( = 0,08 ppm) in the nutrient solution, the effect of Zn only above 10−4moles Zn/l ( = 6,5 ppm).Arranging the tested heavy metals according to their effects leads to the sequenceHg>Pb>Cu>Cd>Cr>Ni>Zn which corresponds – apart from two deviations – to the electrochemical serie

摘要:
AbstractNitrogenase activity (by acetylene reduction assay) has been found on the roots and in the rhizosphere‐soil of various plant species collected from dune soils (Table 1.) located on the west coast of Denmark. Out of twelve plant species, five plant species (Deschampsia flexuosa, Ammophila arenaria, Calluna vulgaris, Empetrum nigrumandCorynephorus canescens) revealed a positive nitrogenase activity. Among these five, three were temperate grasses. ExceptAmmophila arenaria, all four plant species were collected from old sand dune and showed nitrogenase activity on roots as well as in their rhizosphere soil,Ammophila arenariawas collected from fresh sand dune and exhibited nitrogenase activity only on roots (Table 2
