Key messageUse of wood ash or a mixture of wood and oil shale ashes increases the concentrations of P and K in the assimilation organs of conifers and stimulates tree growth. Abstract The effect of fertilization with wood ash (10 and 15 t ha−1) and a mixture of wood ash (10 t ha−1) and oil shale ash (8 t ha−1) on the growth (height, root collar diameter, biomass, biomass production) and nutrient...
Key MessageSecondary chemistry ofP. abiespeaks early in shoot development. Condensed tannins accumulate already in late buds while piperidine alkaloid biosynthesis take place in early stage shoots. Abstract Plants protect new vegetative parts with defensive secondary metabolite compounds. We investigated how concentrations of piperidine alkaloids and condensed tannins change during bud...
Key messageBased on time courses of individual antioxidant compounds, bark phenolic metabolism has been recognised to integrate ascorbate–glutathione system as a redox hub in Norway spruce defence againstCeratocystis polonicainfection. Abstract Temporal courses of individual phenolics, thiols and ascorbate were studied in Norway spruce phloem over a 5-month period after inoculation at...
