The effect of drought on production of dry matter in spring barley (Hordeum vulgare L., cv. Amulet, Krona and historical cv. Nürnberg).

Popis výsledku v původním jazyce

The dry matter production of the spring barley different genotypes was evaluated in selected phases of their ontogeny. Leaf blades mostly had the maximal amount of the dry matter at the beginning of the flowering period, with the subsequent decrease in the phase of the ripening period. Stems usually reached the maximal weight of the dry matter a little bit later, during the milk ripeness phase. When the dry matter content stagnated or began to decrease in vegetative organs, i.e. in the period of ripening between phases of the milk and full ripeness, the generative organs - the spikes - showed an intensive increase of the dry matter. The dynamics of this process was higher in new, modern high-yielding varieties of the spring barley than in the historical variety Nürnberg of 1832. The drought stress was the statistically significant limiting factor of the plant growth of all studied varieties and it critically reduced the growth of the photosynthetic apparatus and prolonged the growth of
