Novotná K., Klem K., Holub P., Rapantová B., Urban O. 2016: Evaluation of drought and UV radiation impacts on above-ground biomass of mountain grassland by spectral reflectance and thermal imaging techniques. -Beskydy, 9 (1-2): 21-30Drought represents one of the major factors limiting productivity of managed and natural ecosystems. Under natural field conditions drought is often associated with other stress factors such as high temperature and UV radiation, which may result in enhancement or vice versa alleviation of drought impact. Remote sensing methods have a large potential to evaluate impacts of drought on plant production at regional scale. The main objective of this study was to analyse the potential of ground-based measurement of spectral reflectance and thermal imaging for monitoring the impacts of drought and UV radiation on above-ground biomass production of mountain grassland ecosystem. Experimental rain-out shelters were used to manipulate incident precipitation and UV radiation for 7 weeks (May-July). A canopy spectral reflectance, thermal images, and total aboveground biomass were determined at the end of drought and UV treatment. Results show that drought led to a significant reduction of above-ground biomass, particularly under ambient UV radiation. In contrary, UV had only negligible effect on biomass production. Canopy temperature as well as selected spectral reflectance indices showed significant response to drought stress and also significant relationships to above-ground biomass. However, the relationship between canopy temperature and above-ground biomass is modified by UV radiation. Best prediction of changes in biomass caused by drought stress was provided by vegetation index NDVI.

“…), an increase in the amount of antioxidant enzymes has also been reported in response to UV-B irradiation in laboratory conditions (Kim et al, 1996). Furthermore, studies conducted so far indicate that the effects of UV-B radiation together with other environmental variables, such as enhanced CO 2 (Bjőrn et al, 1997), high temperature (Mark and Tevini, 1996) and water deficit (Alexieva et al, 2001) are both additive and interactive. However, little attention has been paid to possible simultaneous changes at the level of plant hormones, such as abscisic acid (ABA).…”

“…Over the past two decades these ranged from simple growth room studies of individual plant effects, to outdoor manipulations where UV-B was either screened (Ballaré et al 2001;Day et al 2001;Phoenix et al 2002;Robson et al 2003;Albert et al 2011) or artificially enhanced via fluorescent light frames. Outdoor UV-B enhancement experiments were initiated across the globe and utilised a range of lighting systems from simple square wave (on/off) step-wise control to sophisticated temporal and seasonally modulated systems (Björn et al 1997;Markham et al 1998;Phoenix et al 2001;Musil et al 2002;Caldwell et al 2003;Rozema et al 2006 etc.). UV-B enhancement experiments were most relevant to high latitude regions in relation to ozone depletion impacts.…”

This study investigated the effects of longterm-enhanced UV-B, and combined UV-B with elevated CO 2 on dwarf shrub berry characteristics in a sub-arctic heath community. Germination of Vaccinium myrtillus was enhanced in seeds produced at elevated UV-B, but seed numbers and berry size were unaffected. Elevated UV-B and CO 2 stimulated the abundance of V. myrtillus berries, whilst UV-B alone stimulated the berry abundance of V. vitis-idaea and Empetrum hermaphroditum. Enhanced UV-B reduced concentrations of several polyphenolics in V. myrtillus berries, whilst elevated CO 2 increased quercetin glycosides in V. myrtillus, and syringetin glycosides and anthocyanins in E. hermaphroditum berries. UV-B 9 CO 2 interactions were found for total anthocyanins, delphinidin-3-hexoside and peonidin-3-pentosidein in V. myrtillus berries but not E. hermaphroditum. Results suggest positive impacts of UV-B on the germination of V. myrtillus and species-specific impacts of UV-B 9 elevated CO 2 on berry abundance and quality. The findings have relevance and implications for human and animal consumers plus seed dispersal and seedling establishment.
