“…8). Similar total mean isoprenoid flux rates (28.9-81.5 μg m -2 h -1 ) were also measured from the Pinus sylvestris forest floor in the hemiboreal (Estonia coast) and boreal climates (northern Finland) (Kivimäenpää et al, 2018). Our results were supported by a previous study, where the monoterpene emission rate from decomposition of Pinus sylvestris litter was from five to nearly ten times higher than from decomposition of Picea abies litter within the first 77 days (Isidorov et al, 2010).…”

Emissions of biogenic volatile organic compounds (BVOCs) cool down the global climate via their impacts on aerosol and cloud formation. Climate change will likely have a major impact on BVOC fluxes from the biosphere, including soils, due to temperature-driven plant biosynthesis of volatile organic compounds (VOCs), compound volatility and microbial activity. Soils are a poorly quantified source of VOCs, where the diversity of driving factors creates high spatial and temporal variability in soil VOC fluxes. The aim of this study was to analyse the magnitude and variability of forest floor VOC fluxes, to determine the role of the boreal forest floor in the forest stand BVOC exchange and to estimate plant ecophysiological and microbiological processes, which drive forest floor VOC exchange. Forest floor VOC exchange was determined using a steady-state flow-through chamber technique coupled with mass spectrometry in the boreal and hemiboreal climates. We revealed that the boreal forest floor contributes significantly to forest stand fluxes, but its importance varies between seasons. The forest floor accounted only a few per cent of the total forest stand fluxes of monoterpenes in summer, while in spring and autumn it could be up to 90%. The forest floor VOC exchange was stable between years, while fluxes had clear seasonal dynamic. Monoterpenes and oxygenated VOCs originated from fresh litter, microbial activity, and ground vegetation VOC biosynthesis. Air inside soil layers was found to contain diverse compounds. Forest floor VOC fluxes varied strongly depending on climate and tree species. Atmospheric chemistry may be strongly affected by soils during periods when plant-related BVOC biosynthesis and fluxes are low. In the future, we need continuous and simultaneous VOC exchange measurements from forest floors and forest stands in various ecosystems and climate zones. The global budget for soil VOC emissions should also be defined based on existing studies.

“…Pinus sylvestris is an important source of biogenic volatile organic compounds, which emission rate and profile affect air quality, climate forcing, plant stress tolerance, and thus the growing conditions of forests (Kivimäenpää et al, 2018). The reaction of P. sylvestris to various stress factors (low temperatures, industrial pollution, and action of fungi) showed changes in the content and composition of secondary metabolites (phenols, resins, essential oils).…”

Objective – to investigate the influence of drought on allelopathic activity of Pinus sylvestris L. plants in conditions of M.M. Gryshko National Botanical Garden of the NAS of Ukraine. Material and methods. The choice of study objects was due to their habitat: plants of P. sylvestris grew in compliance with the necessary agricultural technology including regular irrigation at site 1 (control) and in the conditions of drought at site 2 that models natural ecosystems (experiment). The allelopathic activity of leaves and soil was determined. In the model experiments, Lepidium sativum L. ‘Azhur’, Triticum aestivum L. ‘Poliska 90’, Amaranthus caudatum L. ‘Rothschwanz’ were applied as the test plants. Results of the current study revealed that the allelopathic potential of needles and rhizosphere soil of P. sylvestris depends not only from the species but also from drought conditions. The inhibitory effect was stronger against root elongation than shoot elongation of seedlings. Conclusion. This study provides a laboratory-based evidence of the allelopathic effect of P. sylvestris exudates under drought stress on model plants. Studies showed that plants grown under conditions of lower soil moisture exhibit stronger inhibitory effect or slightly stimulate the growth of test objects in comparison with plants that had better water supply. This testifies to the relationship between soil moisture and seasonal allelopathic activity of the plants.

“…Furthermore, some plant species such as woody shrubs (Himanen et al 2010;Mofikoya et al 2018) growing in the understory can act as significant emission sources. On the forest floor, important BVOC emission sources include leaf, needle and wood litter Mäki et al 2017;Kivimäenpää et al 2018) and the root systems of living (Lin et al 2007;Rasheed et al 2017) and dead trees (Haapanala et al 2012;Kivimäenpää et al 2012). BVOC synthesis and emissions by soil microbes in temperate and boreal forests still need similar assessment as in tropical forests (Bourtsoukidis et al 2018).…”

Living trees are the main source of biogenic volatile organic compounds (BVOCs) in forest ecosystems, but substantial emissions originate from leaf and wood litter, the rhizosphere and from microorganisms. This review focuses on temperate and boreal forest ecosystems and the roles of BVOCs in ecosystem function, from the leaf to the forest canopy and from the forest soil to the atmosphere level. Moreover, emphasis is given to the question of how BVOCs will help forests adapt to environmental stress, particularly biotic stress related to climate change. Trees use their vascular system and emissions of BVOCs in internal communication, but emitted BVOCs have extended the communication to tree population and whole community levels and beyond. Future forestry practices should consider the importance of BVOCs in attraction and repulsion of attacking bark beetles, but also take an advantage of herbivore-induced BVOCs to improve the efficiency of natural enemies of herbivores. BVOCs are extensively involved in ecosystem services provided by forests including the positive effects on human health. BVOCs have a key role in ozone formation but also in ozone quenching. Oxidation products form secondary organic aerosols that disperse sunlight deeper into the forest canopy, and affect cloud formation and ultimately the climate. We also discuss the technical side of reliable BVOC sampling of forest trees for future interdisciplinary studies that should bridge the gaps between the forest sciences, health sciences, chemical ecology, conservation biology, tree physiology and atmospheric science.
