Modeling of bud break of Scots pine in northern Finland in 1908–2014
Bud break and height-growth of Scots pine (Pinus sylvestris L.) in the northern boreal zone in Lapland, Finland, was followed through the entire growing seasons in the periods 2001-2003 and 2008-2010 in sapling stands in two different locations in northern Finland set some 250 km apart along a latitudinal transect. Field measurements continued at the southern site also in 2011-2013. Air tempera...
متن کاملNatural Regeneration of Scots Pine and Norway Spruce Close to the Timberline in Northern Finland
Two different datasets were analyzed in order to clarify the factors that affect regeneration success of Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) in the climatically extreme areas in northern Finland. First, pine seed maturity and the number of cones in the trees were investigated at five pairs of study sites during the period 1997–2003. Secondly, the rate of seedling estab...
متن کاملPotential litterfall of Scots pine branches in southern Finland
Litter input drives dynamic soil models that are used to understand the flows and stocks of soil carbon. In estimation of above-ground litterfall, much of the uncertainty lies in the turnover rate of branches. The objective of this study was to develop a model for estimating the branch litterfall of Scots pine stands. Here the potential litterfall of branches was modelled as a function of tree ...
متن کاملThe effect of temperature and PAR on the annual photosynthetic production of Scots pine in northern Finland during 1906–2002
The annual photosynthetic production of Scots pine (Pinus sylvestris) was simulated for 1906–2002 for a location in northern Finland. We used the PhenPhoto model, which combines two key features of photosynthesis: the response to instantaneous radiation and the acclimation to the annual cycle. The input data for the PhenPhoto model include instantaneous photosynthetically active radiation (PAR)...
