Description
| - An unusual disorder occurred on spring barley seedlings in southern a central Bohemia in April 2005. Affected seedlings showed conspicuous bleached or straw-coloured areas on tips of the first leaves. There were very sharp, distinct, horizontal boundaries between green basal and colourless tip parts of the leave blades. It was remarkable that these horizontal boundaries were in a similar position on each first leaves of all affected seedlings originating from the same fields. Field examination showed an individual, random distribution pattern of affected seedlings in a number of approximately five symptomatic plants per 10 m2. Based on meteorological data, it can be concluded that the colour abnormality on emerging barley seedlings in the CR in 2005 was associated with specific environmental stresses, being effective in certain chronological order on sensitive plant tissues during the sixth to eight days after seeding. These stresses include frosty mornings followed by clear days with high solar radia

- V roce 2005 se v jižních a středních Čechách vyskytla v porostech jarního ječmene na vzcházejících rostlinách neobvyklá barevné abnormalita. Na postižených rostlinách odrůdy Tolar a Prestige CPG byly nápadné souvislé vybělené nebo slámově žluté plochy na vrcholech prvních listů. Příznakové rostliny byly náhodně rozmístěny po celém porostu v množství okolo 5 rostlin na 10 m2. Porucha zbarvení listů souvisela se specifickými povětrnostními stresy působícími v určité posloupnosti v citlivé vývojové fázi rostlin během šestého až osmého dne po zasetí. Těmito stresy byla mrazivá rána, po nichž následovaly jasné dny s vysokým slunečním zářením a vysokým indexem UV-záření. Hlavní klíč. slova: ječmen jarní, barevné abnormality, podmínky prostředí, UV záření, ČR (cs)
