“…According to results from this study cultivars had a later optimal time of harvest (16–18 DAA) than breeding lines and wild populations (11–13 DAA). Results of a previous study (Sahramaa and Hömmö, 2000) also supported this finding, which indicated the best harvest time for cultivar Palaton to be 15 DAA. In general, the later the harvest the lower the seed yield and panicle weight and the higher the seed shattering.…”

Problems related to seed production, including yield.

The research material included eight cultivars, tion in RCG for seed production traits. Since RCG is 14 breeding lines, and 53 Finnish wild populations, which were divided an outbreeder, it is highly heterozygous and variable into 10 groups according to their origin. Results indicated that populations of reed canarygrass differed markedly in seed production traits. for many traits.

“…Na problémy s často i extrémně nízkou klíčivostí semen této trávy upozorňuje například Wheaton (1993). Sahramaa a Hömmö (2000) odůvodňují nízkou klíčivost nerovnoměrným dozráváním semen této trávy či špatně zvoleným termínem sklizně. V rychlosti klíčení vynikal druh Elymus elongatus, jehož semena začala klíčit vždy po 3 dnech od založení pokusu.…”

In order to gain a sufficient amount of phytomass for the needs of eco-energetics, there are monocultural grasslands established on the arable land. In the context of the changing climate and more frequent periods of drought, it is important to look for grass species and varieties that are able to withstand these stress conditions. Influence of droughtness on germination of four selected energy grass species is decribed in paper. The investigated species were tall meadow oat (Arrhenatherum elatius L.) -the Median variety, orchard grass (Dactylis glomerata L.) -the Padania variety, tall wheatgrass (Elymus elongatus) -the Szarvasi-1 variety and reed canary grass (Phalaris arundinacea L.) -the Chrastava variety. Although the species differed in the germinability (p < 0.001), the significant differences in their drought resistence were not found (p > 0.05) Keywords: Drought resistance, energetical plants, germinability, grassland, water stress Abstrakt Za účelem získání dostatečného množství fytomasy pro potřeby ekoenergetiky jsou dnes na orné půdě zakládány monokulturní porosty trav. V souvislosti s měnícím se klimatem a častějšími obdobími sucha je důležité hledat druhy a odrůdy, jež jsou schopny těmto stresovým podmínkám odolat. V článku jsou popsány výsledky vlivu sucha na klíčení semen čtyř vybraných travních druhů vhodných pro energetické využití.
