Biological characteristics and coverage of Anthriscus sylvestris and Achillea millefolim in permanent grasslands
ZAVÁZALOVÁ, Zuzana
This thesis is focused on the problems connected with grasslands, their division, functions, farming, exploitation and environmental factors which influence the composition of vegetation and forage quality. It also deals with the composition of permant grasslands and their types. One separate chapter is devoted to the importance of herbs in grasslands and there are also stated examples of herbal mixtures. The main goal of this work is to describe the issue concerning milfoil (Achillea millefolium L.) and chervil (Anthriscus sylvestris L.), their biology, ecology and involvement in different types of grasslands. Individual chapters which are dedicated to each specific herb are always preceded by description of their families, their significance and application. Following chapters are about geographical spread and inventory of kinds of these specific herbs (chervil and milfoil), their description, morphology, ecology, cenologiii, forage quality, significance and application in grasslands. In the second part to supplement the findings of research on presence of milfoil and chervil there are written results of my own observation (charts and graphs) showing the projective dominance of milfoil and chervil in different types of grasslands with different farming and their height achieved in different periods of time. The charts and graphs show species composition and projective dominance of grasses, legumes and other herbs including their height at the highest achieved arithmetic average of vegetation height.
