Objetivo TO GENERATE SCIENTIFIC INFORMATION IN ORDER TO ELUCIDATE TO WHAT EXTENT ENVIRONMENTAL LIMITING FACTORS MODIFY THE PLANT RESPONSE TO AIR POLLUTANTS. UNDER CONTROLLED AND REPRODUCTIBLE CONDITIONS IN CLIMATIC CHAMBERS, AND IN AN OPEN TOP UNIT FUMIGATION EXPERIMENTS WITH CHRONIC EXPOSURES TO 03, SO2 AND NO2, SINGLY AND IN COMBINATION, WILL BE CARRIED OUT. IF CORRELATED WITH FIELD EXPERIMENTS IN THE SO2 ACCENTUATED FICHTEL GEBIRGE AND IN THE O3 ACCENTUATED SOUTHERN BLACK FOREST, THE RESULTS MAY HELP TO EXPLAIN THE INFLUENCES OF THE POLLUTANTS MENTIONED ABOVE ON THE INTERRELATIONS BETWEEN PLANT, PATHOGENICS AND CLIMATICAL STRESS. INFLUENCED BY AIR POLLUTANTS AND BY BOTH BIOTIC AND ABIOTIC STRESS, THE VITALITY OF THE TEST PLANTS - PINTO BEAN (PHASEOLUS VULGARIS), SPINACH (SPINACEA OLERACEA) AND SPRUCE (PICEA ABIES KARST.) - WILL BE ANALYSED USING THE FOLLOWING RESPONSE CRITERIA : -DIAGNOSIS OF PHOTOSYNTHESIS AND RESPIRATION -DETERMINATION OF THE REDUCTION EQUIVALENTS NAD, NADH, NADP, NADPH2 -DETERMINATION OF THE NUCLEOTIDS ATP, ADP, AMP TO MEASURE THE ENERGY BALANCE OF THE PLANT -DETERMINATION OF THE PROTEIN, CARBOHYDRATE AND PIGMENT CONTENTS -DETERMINATION OF THE ACTIVITY OF THE ENZYMES PEROXIDASE AND ACID PHOSPHATASE Ámbito científico natural sciencesbiological sciencesmicrobiologymycologyengineering and technologyenvironmental engineeringair pollution engineeringnatural sciencesbiological sciencesbiochemistrybiomoleculescarbohydratesnatural sciencesbiological sciencesbiochemistrybiomoleculesproteinsenzymesnatural sciencesbiological sciencesbotany Programa(s) FP1-ENVPROT 4C - Multiannual research and development programmes (EEC) in the field of the environment - Protection of the environment -, 1986-1990 Tema(s) Data not available Convocatoria de propuestas Data not available Régimen de financiación CSC - Cost-sharing contracts Coordinador Universität Gesamthochschule Essen Aportación de la UE Sin datos Dirección Henry-Dunant-Straße 65 45131 Essen Alemania Ver en el mapa Coste total Sin datos
