This article reflects on three recent publications dealing with broadside ballads in the Czech lands. These include a publication from regional museum collections and two exhibition catalogues. It presents the various ways of comprehending this interdisciplinary phenomenon and current research trends (research into the materiality of the prints, reflection on the musical component, multilingualism and the like). It also presents terminological considerations and reflects on the broadside ballad as part of 18th and 19th century popular culture.
This study was conducted to assess whether silicon (Si) supply can alleviate the harmful effects of severe salinity in barley (Hordeum vulgare). Plants were grown on non-saline (0 mM NaCl) or saline (200 mM NaCl) nutrient media supplemented or not with 0.5 mM Si. Salinity impacted plant morphology and induced sodium and chloride accumulation within plant tissues. It significantly affected almost all measured parameters. Interestingly, Si supply alleviated salt stress effects on plant morphology, growth (up to +59%), water status (up to +74%), membrane integrity (up to +35%), pigment contents (up to +121%), and the activity of the two photosystems (PSI and PSII) by improving their yields, and by reducing their energy dissipation. Si beneficial effect was more pronounced on PSI as compared to PSII. As a whole, data inferred from the present study further confirmed that silicon application is an effective approach to cope with salinity.
