Abstract

We tested the influence of exogenous application of brassinosteroids (BRs) on survival, growth and biomass production of Scots pine (Pinus sylvestris) seedlings. BRs are natural substances, supposedly having many positive effects on plants such as improving growth, stress tolerance, survival and biomass production. One part of the seedlings was treated with a low concentration of synthetically prepared BRs and the other part was designated as the control without any treatment. Mortality, height and root collar diameter were measured in two subsequent years, the root-to-shoot ratio of biomass volume was determined in autumn 2013. The application of BRs significantly slowed height and radial growth of pine. The height increment of the BRs-treated seedlings was lower by 11% between 2012 and 2013 compared to the control. The increment in root collar diameter (2012-2013) in the BRs-treated seedlings was lower by 13% than in the control. The BRs-treated pines also experienced a significantly higher mortality compared to the control. No significant influence of BRs on biomass production was found.
