Pollen counts from Kasten corer CON01-603-5 at CONTINENT Ridge.
Sediment slices of 0.5 cm thickness were obtained from gravity core segments and of 1 cm thickness from the Vydrino piston core. Volumetric subsamples of 5 cm3 (10 cm3 in case of the lowermost samples from Continent core) were prepared according to standard procedures, including 7-μm ultrasonic fine-sieving (Cwynar et al., 1979, Fægri et al., 1989 K. Fægri, P.E. Kaland and K. Krzywinski, Textbook of Pollen Analysis (4th edition), John Wiley & Sons, Chichester (1989) 328 pp..Fægri et al., 1989 and PALE Steering Committee, 1994). Two tablets of Lycopodium marker spores were added to each sample for calculating total pollen and spore concentrations (Stockmarr, 1971). Water-free glycerol was used for storage and preparation of microscopic slides. The palynological samples were counted at magnifications of 400–600×, applying 1000× for the identification of difficult pollen types, e.g., including Saxifragaceae, Crassulaceae, and Rosaceae.

The Aim and Innovation of the Research are the Determination and Evaluation of the Multifactorial Effects on Plant Production, Product Quality and Plant Metabolism. The Project Consists of the Following: A.Investigation of Multifactorial Effects of Acid Air Pollutants on Compartments of Grassland Plots under Defined Conditions. B.Investigation of Multifactorial Effects of Acid Air Pollutants on the Agricultural Plants Lolium, Festuca,Hordeum, Zea Mays and Solanum Tuberosum under Defined Conditions.
Schaffung und Erhaltung von Graesersorten, die sich durch herausragende Krankheitsresistenz, Ausdauer und Konkurrenzkraft auszeichnen, sich dadurch bestmoeglich fuer den Futterbau als Komponente umweltschonender Anbausysteme eignen und dank hoher Futterqualitaet zu einer optimalen Umsetzung der betriebseigenen Rauhfutterbasis beitragen.
