Název v původním jazyce

The effect of soil drought on the water use efficiency in spring barley (Hordeum vulgare L.)

Popis výsledku v původním jazyce

On the leaves of two modern varieties (Jersey and Malz) and one old variety (Valtický) of spring barley (Hordeum vulgare L.), the stress responses caused by soil drought were studied. The plants were cultivated at 70 % &#952;MKK. The stress was brought about by interrupting irrigation at the beginning of shooting (31.DC) and by gradual drying-up of the substrate for a period of 10 days down to 30 % &#952;MKK. At selected ontogenetic stages (13.DC, 15.DC, 21.DC, 31.DC, 33.DC, 39.DC, 51.DC and 61.DC) relative water content (RWC) and the gas exchange parameters (gs, A and E) were measured, and these data were used to calculate the water use efficiency (WUE). It was found out that WUE can be used to evaluate the drought-resistance of varieties of spring barley. Although with respect to RWC > 80 %, only a mild stress occurred, the examined genotypes manifested contrast responses to the decrement of water in the substrate with respect to WUE. It can be said that the Malz variety can manage w
