Excess water in the rooting zone critically reduces tree growth and may even kill trees; however, the relative importance of damage to roots versus aboveground parts and the time course of damage are not well understood. We studied the dynamics of fi

Future climate scenarios for the boreal zone project increasing temperatures and precipitation, as well as extreme weather events such as heavy rain during the growing season. This can result in more frequent short-term waterlogging (WL) leading to u

The aboveground parts of boreal forest trees mostly grow earlier, and the roots later, in the growing season. We aimed to experimentally test whether the extrinsic driver of soil temperature or the intrinsic driver (resource competition between plant

Root system health is a key factor for seedling quality and it is a prerequisite for the proper growth of seedlings after out-planting. If the seedlings are moved to freezer storage too early in the season, roots can be damaged and thereby the qualit

In the future management and sustainable use of boreal forests, it is crucial to consider the rate and strength of tree responses to an elevated water table and the concurrent oxygen limitations, especially in peatlands. We examined the response dyna

We demonstrate the effect of water-soluble starch on an electrochemical impedance spectrum with the aim of sensing starch concentration in an aqueous solution. The characteristic form of the relative dielectric dispersion curves with respective loss

A novel non-destructive method is presented for studying the frost hardiness of roots. Principal component analysis from the electrical impedance spectra revealed differences between freezing temperatures, but no clear differences between the mycorrh

To investigate whether root colonisation of Scots pine (Pinus sylvestris L.) seedlings with symbiotic mycorrhizal fungi (Hebeloma sp. and Suillus luteus) could be detected in situ, classification analysis of the electric impedance spectra (IS) of the

Here we consider the optical and the chemical effects of a phosphate buffered saline (PBS), to titanium (Ti) surfaces. Compound (Ti, TiO, TiO 2 and Ti 2 O 3 ) analysis was conducted for native surfaces as well as for ultra pure water exposed and for

Directional dependence of adsorbed human plasma fibrinogen (HPF) and human serum albumin (HSA) on highly ordered pyrolytic graphite (HOPG), on polished titanium (Tip), and on titanium with a light-induced periodic surface structure (TiLIPSS) was inve
