Silver birch (Betula pendula Roth) allocates substantial resources to the production of glandular trichomes. If these trichomes can protect trees from temperature and water stress, their would be expected increase under conditions. We studied how trichome density number in leaves two-year-old silver plantlets respond single combined treatments elevated (+1 °C) three different levels soil moisture (low, normal, excess watering). Moreover, we quantified seasonal variation mature long-shoot...
Abstract In the absence of chemical control with its negative side effects, fungal pathogens can cause large yield losses, requiring us to develop agroecosystems that are inherently disease resistant. Grassland biodiversity experiments often find plant species diversity reduce pathogen pressure, but whether incorporating high levels in agricultural fields have similar effects remains largely unknown. We tested if undersown could barley disease, and effect was mediated through above- or...
Abstract Despite active research, antiherbivore activity of specific plant phenolics remains largely unresolved. We constructed silver birch ( Betula pendula ) lines with modified phenolic metabolism to study the effects foliar flavonoids and condensed tannins on consumption growth larvae a generalist herbivore, autumnal moth Epirrita autumnata ). conducted feeding experiment using in which expression dihydroflavonol reductase DFR ), anthocyanidin synthase ANS or ANR had been decreased by...

Abstract Accumulation of certain phenolics is a well‐known response plants to enhanced UVB radiation (280–315 nm), but few experiments have compared the relative importance different phenolic groups for resilience. To study how an altered profile affects responses and resilience silver birch ( Betula pendula ) UVB, we used RNA interference (RNAi) targeting dihydroflavonol reductase (DFR), anthocyanidin synthase (ANS), or (ANR) change accumulation phenolics. The unmodified control line...
