Influence of nitrogen and phosphorous availability and ozone stress on Norway spruce seedlings.
Four-year-old Norway spruce (Picea abies L. (Karst.)) seedlings were exposed to ambient and elevated (1.5 x ambient in 1997 and 1.6 x ambient in 1998) ozone concentrations [O3] and three nitrogen (N) and two phosphorus (P) availabilities: "optimal" values (control); 70% of the control N and P values (LN and LP); and 150% of the control N value (HN). Treatments were applied in an open-field ozon...
متن کاملSoil temperature, gas exchange and nitrogen status of 5-year-old Norway spruce seedlings.
Five-year-old Norway spruce (Picea abies (L.) Karst.) seedlings were subjected to three simulated growing seasons in controlled environment chambers. Plants were acclimated to a soil temperature of 16 degrees C during the first and third growing seasons, but were allocated at random to soil temperature treatments of 9, 13, 18 and 21 degrees C during the second growing season. Low soil temperatu...
متن کاملOzone detoxification of steam-pretreated Norway spruce
BACKGROUND Pretreatment of lignocellulose for biochemical conversion commonly results in formation of by-products that inhibit microorganisms and cellulolytic enzymes. To make bioconversion processes more efficient, inhibition problems can be alleviated through conditioning. Ozone is currently commercially employed in pulp and paper production for bleaching, as it offers the desirable capabilit...
متن کاملCytokinins in Norway Spruce Seedlings and Forest Soil Pollution
KRAIGHER H. & HANKE D.E. 1996. Cytokinins in Norway spruce seedlings and forest soil pollution. Phyton (Horn, Ausrtia) 36 (3): (57) (60). Cytokinins can correlate with pollution damage in spruce trees and also with different strains and species of their mycorrhizal symbionts. In our study, Norway spruce seedlings were grown in vitro on sterilized or nonsterile soil substrates from two different...
