Adaptation strategies to climate change - the seed vigour

Popis výsledku v původním jazyce

Seed vigour is the ability of seeds to germinate and form the basis for a new plant under stress conditions (drought, low temperatures, the lack of nutrients). In rapidly changing climatic conditions seed vigour become increasingly important seed characteristics. Vigorous seeds are able to withstand stressful environmental conditions at an early stage of growth (e.g. so-called "drought escape"). The aim of the study was to evaluate the seed vigour of barley (Hordeum vulgare L.) and winter wheat (Triticum aestivum L.) in dry and cold conditions and to quantify the relationship between seed vigour and root system size. The vigour of the seeds was evaluated in the laboratory under the influence of drought stress -0.5 MPa in a water solution of polyethylene glycol (PEG 6000) and temperature of 10 oC. Testing of relationships between the size of the root system and the vitality of seeds did not yield conclusive correlation. However, a closer correlation can be expected only in dry years. Th
