Ecophysiological aspects of Cirsium arvense

Abstract

Even if an existing agricultural holistic production system works without specific measures of control of Cirsium arvense (L.) SCOP. scientific questions of pedogene probiotic aspects are left to be answered. Changes in soil structure and pH-Value are not as much due to the conditions of soil but depend on the influences of the Creeping thistle. Investigations of soils with/without thistles at the University of Hohenheim show high differences which hint at saprotroph contributions to nutrition. Thistle growth, rhizome dormancy and subterranean embryogeny are discussed as a nutrition model of thistles as mixotroph plants which can take advantage of organic substances in the soil.
