Dragan-Bularda, M. | Pascu, Monica (Universitatea Babes-Bolyai, Cluj, (Romania))
Evolution of the activity of five polysaccharides (amylase, inulase, cellulase, dextranase and levanase) was studied in relation with physicochemical soil properties and season, in three soil types (leached chernozem, brown forest soil and alluvial soil), the samples of which were collected in each season of 1996. It was found that all five polysaccharisade activities were present in the studied soils, with differences depending on the season, on the soil type and soil properties. The most intensive activity was the amylase one, followed by inulase, dextranase and levanase activities, the less marked being the cellulase activity. The soil types exhibited differences concerning their polysaccharisade activity. The leached chernozem had the most intensive polysaccharisade activity. Generally, polysaccharisade activity also depending on the season, having a high value in spring an autumn, a lower value in summer and the lowest level in winter.
