    Evaluation of barley seed vigour and its relationship with fungi infection

  • Original language description

    The quality of spring malting barley caryopses (Hordeum vulgare L.) was examined using several parameters. Thirty six seed lots obtained from variety trials harvested in 2002 were evaluated. Vigour estimated as germination under stress conditions, i.e. low temperature and water stress, showed large differences among seed lots, which ranged from 20,5 to 100 % of germinated seeds. However the influence of location (i.e. environmental conditions) on vigour was much higher than that of cultivar, statistically significant differences among cultivars were found. Another criterion was a fungi infection characterised by the presence and quantity of ergosterol. Significant negative correlation between vigour and ergosterol content suggests that the ergosterol analysis may contribute to the description of seed quality.

    Vitalita osiva ječmene ke vztahu k houbovým infekcím

  • Czech description

    Kvalita 36 vzorků osiva jarního sladovnického ječmene byla hodnocena pomocí několika ukazatelů. Pro sledování vitality byla použita metoda klíčení za stresových podmínek, nejnižší klíčivost byla 20,5 % a nejvyšší 100 %. Vitalita byla ovlivněná jak místempěstování, tak odrůdou. Dalčím kriteriem bylo hodnocení výskytu plísní na osivu pomocí stanovení obsahu ergosterolu v zrnu ječmene. Byla zjištěna statisticky průkazná záporná korelace mezi vitalitou osiva a množstvím erosterolu.
