BVOC responses to realistic nitrogen fertilization and ozone exposure in silver birch
Environmental Pollution, Jun 1, 2016

For the first time, BVOC emissions were explored in a forest tree species (silver birch, Betula pendula) exposed for two years to realistic levels of O3 (35, 48 and 69 ppb as daylight average) and N (10, 30 and 70 kg ha(-1) yr(-1), applied weekly to the soil as ammonium nitrate). The main BVOCs emitted were: α-pinene, β-pinene, limonene, ocimene, (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT) and hexanal. Ozone exposure increased BVOC emission and reduced total leaf area. The effect on emission was stronger when a short-term O3 metric (concentrations at the time of sampling) rather than a long-term one (AOT40) was used. The effect of O3 on total leaf area was not able to compensate for the stimulation of emission, so that responses to O3 at leaf and whole-plant level were similar. Nitrogen fertilization increased total leaf area, decreased α-pinene and β-pinene emission, and increased ocimene, hexanal and DMNT emission. The increase of leaf area changed the significance of the emission response to N fertilization for most compounds. Nitrogen fertilization mitigated the effects of O3 exposure on total leaf area, while the combined effects of O3 exposure and N fertilization on BVOC emission were additive and not synergistic. In conclusion, O3 exposure and N fertilization have the potential to affect global BVOC via direct effects on plant emission rates and changes in leaf area.

Trees in the urban environment: response mechanisms and benefits for the ecosystem

In this scenario arbo-riculture and urban forestry should have a main role in the effort to manage urbanization and to create livable cities and it is certain that all green areas, starting from the single tree specimens to periurban forests which, in some way, recall the " concept of nature " , can fulfil a paramount function in improving life quality and in reaching the minimal threshold for human well-being. What is going to happen next – over 10-15 years – will obviously be of the greatest interest to all people concerned with urban environment. This latter poses some constraints to tree growth and survival: drought, poor soil quality and compaction, pollutants, salinity, pathogens, light heterogeneity, and conflicts with human activities often cause premature plant death or limit plant growth, thus reducing the net benefit by urban green areas. It is therefore important to better understand the dynamics leading to tree decline in the urban environment, and to develop strategies and techniques aimed at improving the horticultural tolerance (i.e. the capacity to provide benefits, not only to survive, under stressful conditions) of urban trees. These include nursery pre-conditioning techniques and post-planting management techniques, but a key role is played by species selection. Hundreds of species are used in the urban environment, but selection criteria are frequently based upon aesthetics and whether the species are native or not, rather than on the tolerance to typical stresses imposed by the built environment and on the capacity to provide substantial benefits therein.

To test this hypothesis we grew three woody species of the Oleaceae family, the evergreen Phillyrea latifolia (sun‐requiring), the deciduous Fraxinus ornus (facultative sun‐requiring) and the hemi‐deciduous Ligustrum vulgare (shade tolerant) at 30 or 100% sunlight irradiance. We show that neither mesophyll conductance calculated with combined gas exchange and chlorophyll fluorescence techniques (gm) nor CO2 assimilation significantly varied in F. ornus because of sunlight irradiance. This corroborates previous suggestions that species with high plasticity for light requirements, do not need to undertake extensive reorganization of leaf conductances to CO2 diffusion to adapt to different light environment...

That anthocyanins may protect leaves in plants facing biotic or abiotic stressors, an idea dating back to Pringsheim (1879), is arguably the most widely accepted function for foliar anthocyanins, although the mechanism(s) by which they could mitigate effects of stress remains heatedly debated. In addition to the most frequently discussed putative roles of anthocyanins as antioxidants and sunscreens, other less-explored possibilities might equally serve to ameliorate plant function under, for example, under conditions of mineral imbalance. In particular: (i) anthocyanins may serve as metal-chelating agents under conditions of excess edaphic metal ions and (ii) anthocyanin accumulation might delay foliar senescence, which is otherwise usually accelerated in plants growing under macronutrient deficiency. The latter mechanism might be particularly advantageous to prolong plant survival and increase the possibility of reproductive success. 2015 Published by Elsevier B.V.

Effect of increasing nutrient concentration on growth and nitrogen uptake of container-grown peach and olive

Dry matter production of peach was closely related to nutrient supply, whereas olive plants did not correlate with the ionic strength of the nutritive solution. Peach and olive plants exhibited large differences in biomass partitioning: peach always showed a higher root/shoot ratio. As the nitrate supply was increased an enhanced nitrogen absorption was observed in peach. On the other hand, olive appeared to be unable to take up and assimilate such supplies.
