The phenomenon of desiccation tolerance involves numerous poikilohydric groups such as algae, lichens, mosses, cyanobacteria, fungi, seeds and spores under dormancy and vascular plants. In contrast to this, most of the higher plants are not able to survive desiccation. However, the capability to cope with the harmful effect of the lack of water supply requires the complex integration of many adaptation mechanisms. Vascular plant species belonging to the same desiccation-tolerance strategy group produce different reactions, which reflect the degree of their adaptation ability. The main questions of the proposed project are: reveal of the regeneration ability of desiccation tolerant plant species following to be in long-term (20 years) desiccation state, of the background mechanisms of temporal dynamics referring to photosynthetic and catabolic activities, of the revival ability and investigate the regeneration degree. Investigations will seek identify substances and systems are important in mechanisms take part in maintenance the integrity of membranes and macromolecule structures during desiccation and prevent the oxidative damage during rehydration.
The aim of the research to reveal the changes of the dominance relations in the plant communities of the pastures and meadows caused by climate change using plant physiological and traditional plant coenological methods with measuring the intensity change of ecological parameters. Furthermore, in the hay and grazed plant stock, a significant proportion or it would also involve investigations of the chemical (carbohydrate, protein and lipid) composition of plant species with feed value. For the effects of abiotic factors as stressors, plants as stress response can modify the nature and type of carbohydrate like storage formations inside the cells. These alternations can be intensified with the more expression of the environmental stress factors implying global climate change, which can resulting quality changes in hay component forage and cereals. In veterinary aspects, it also can be pointing forward on feeding and disease diagnosis as in avoidance of pasture-associated laminitis, can point out the periodic inhibition of grazing in the future. It can be conductive to select the adequate plant species in case of feeding purposes of artificial pastures.
