“…Similarly like in our experiment, Castellano (1996) and Garbaye and Churin (1997) reported an indifferent impact of fungal inoculation on the survival and growth of outplanted seedlings. However, a stimulative effect of inoculation on seedling growth in some fungus-tree species-environment combinations was observed as well (Marx 1991;Castellano 1996;Garbaye, Churin 1997).…”

“…However, a stimulative effect of inoculation on seedling growth in some fungus-tree species-environment combinations was observed as well (Marx 1991;Castellano 1996;Garbaye, Churin 1997). Querejeta et al (1998) pointed out that the inoculation effect (spores and forest soil) on seedling development depends on the mechanical preparation of soil and a positive response of seedlings to fungus application is more feasible in a water stress period.…”

Bareroot and containerized seedlings (seedling type) of Norway spruce, Scots pine, European larch, European beech, and sycamore maple were outplanted in autumn 2008 and in spring 2009. Roots of a half of the seedlings were dipped into the commercial fungal product Ectovit prior to spring outplanting. Fifty seedlings were planted for each tree species and seedling type in each of 3 treatments (Autumn, Spring, Spring+Ectovit) and 3 replications (4,500 seedlings in total). Eighty-one per cent of containerized and 75% of bareroot seedlings (most -89% of bareroot spruce, least -59% of bareroot pine seedlings) survived after the first growing season. Planting time and Ectovit did not have a marked effect on survival, with the exception of the lower survival of containerized beech and spruce in autumn than in spring. The most extensive damage caused by game and mechanical weed control was found out in both broadleaves; most of the dry leading shoots occurred in beech. Besides beech, higher annual height increment of seedlings was observed in autumn than in spring planting time. Effect of Ectovit on seedling growth was not obvious.

“…Ectomycorrhizal symbioses may improve water status of saplings [49] and probably also trees under drought, by means of increased absorbing surface, of efficient conduction through mycelial strands, of enhanced hydraulic conductivity at the soil-root interface or of hormonal and nutritional effects modifying stomatal regulation of the tree [18,61,62]. Development of mycorrhizal roots considerably increases the exchange surface of the root system.…”

Temperate forest trees and stands under severe drought: a review of ecophysiological responses, adaptation processes and long-term consequences

-The extreme drought event that occurred in Western Europe during 2003 highlighted the need to understand the key processes that may allow trees and stands to overcome such severe water shortages. We therefore reviewed the current knowledge available about such processes. First, impact of drought on exchanges at soil-root and canopy-atmosphere interfaces are presented and illustrated with examples from water and CO 2 flux measurements. The decline in transpiration and water uptake and in net carbon assimilation due to stomatal closure has been quantified and modelled. The resulting models were used to compute water balance at stand level basing on the 2003 climate in nine European forest sites from the CARBOEUROPE network. Estimates of soil water deficit were produced and provided a quantitative index of soil water shortage and therefore of the intensity of drought stress experienced by trees during summer 2003. In a second section, we review the irreversible damage that could be imposed on water transfer within trees and particularly within xylem. A special attention was paid to the inter-specific variability of these properties among a wide range of tree species. The inter-specific diversity of hydraulic and stomatal responses to soil water deficit is also discussed as it might reflect a large diversity in traits potentially related to drought tolerance. Finally, tree decline and mortality due to recurrent or extreme drought events are discussed on the basis of a literature review and recent decline studies. The potential involvement of hydraulic dysfunctions or of deficits in carbon storage as causes for the observed long term (several years) decline of tree growth and development and for the onset of tree dieback is discussed. As an example, the starch content in stem tissues recorded at the end of the 2003's summer was used to predict crown conditions of oak trees during the following spring: low starch contents were correlated with large twig and branch decline in the crown of trees. drought / water balance / time lag effect / hydraulic properties / dieback Résumé -Arbres et peuplements forestiers tempérés soumis à sécheresse : une revue des réponses écophysiologiques, des processus d'adaptation et des conséquences à long terme. La sécheresse exceptionnelle de 2003 a été l'occasion de faire le point de nos connaissances sur les mécanismes écophysiologiques permettant aux arbres de traverser un tel évènement climatique extrême. L'analyse a été conduite à l'échelle de l'arbre et du peuplement, tandis que l'intensité de la sécheresse a été quantifiée à l'aide d'un calcul de bilan hydrique sur neuf sites forestiers européens contrastés du réseau CARBOEUROPE. Le rôle du couvert dans les échanges avec l'atmosphère est rappelé puis intégré dans l'analyse des réductions de bilan d'eau et de carbone en 2003 dus à la régulation stomatique. Les caractéristiques du complexe sol-racine, important à la fois pour l'accès à la ressource et à l'efficience de son absorption, constituent un des premiers traits d'ada...

Plant genetic effects on soils under climate change

Background In the face of climate change, shifts in genetic structure and composition of terrestrial plant species are occurring worldwide. Because different genotypes of these plant species support different soil biota and soil processes, shifts in genetics are likely to have cascading effects on ecosystems. Scope We explore plant genetic effects on soil function in the context of climate change, and selection by soils, soil biota and plant-soil feedbacks. We propose categories of genetically-based plant traits that should be prioritized in research on genetic-based effects on soil processes including plant productivity and C allocation, tissue quality, plant water-use, and rhizosphere mutualisms. Additionally, we posit that soil community responses to climate change should be considered in concert with plant genotype because of sensitivity of soil communities to climate. We use two case studies to highlight these points. Conclusions We argue that the effects of climate change as an agent of selection on plants may cascade to affect soils, and ultimately the structure, composition and function of ecosystems. Understanding the ecological and evolutionary potential of plant-soil linkages may help us understand and mitigate the extended consequences of global change for ecosystems worldwide. Accordingly, we conclude with experimental approaches for examining genetically-based plant-soil interactions across climate change gradients.Plant Soil (2014) 379:1-19 DOI 10.1007/s11104-013-1972-x Responsible Editor
