Drivers of fine root phenology of boreal trees in changing climate (RootPheno)

RootPheno

The aim is to study how different extrinsic and intrinsic drivers affect fine root phenology of boreal tree species, Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) Karst.), silver birch (Betula pendula Roth) and pubescent birch (Betula pubescens Ehrh.). We draw conclusions about the effects of root phenology and its changes on growth and productivity of trees under changing climate conditions during winter and growing season. According to the results we develop a model for fine root phenology. A novel non-destructive method will be developed for root studies that is based on electrical properties of roots. We carry out new experiments in controlled conditions and utilize data of our previous experiments carried out in field and controlled conditions.
