- Abstract:
- ... CONTEXT : Genetic diversity of sessile oak (Quercus petraea) populations in Hungary was assessed close to the retracting, low-elevation, low-latitude (xeric) distribution limits. OBJECTIVE : We aimed at tracing an assumed effect of climatic factors on genetic diversity, particularly at the southern, low elevation limits of distribution. METHODS : Genetic diversity at isozyme-coding loci was analys ...

- Abstract:
- ... CONTEXT: J. regia timber is appreciated for high-value wood products. In new plantations, biotic or abiotic events which could affect wood quality should be monitored. Autumn frosts could affect annual shoot development, with consequent loss of timber value or even tree death. In southern Europe, climate change forecasts include erratic and severe autumn frost events. AIMS: The relationship betwee ...

However, growth responses of these tree populations to those stressors may vary along climatic gradients. AIMS : To analyze growth responses to climate and drought using dendrochronology in rear-edge Pinus nigra populations located along an aridity gradient. METHODS : Tree-ring width ch ...

The magnitude of maturation stress differs between longitudinal and tangential directions, and between normal and tension woods. AIMS : We aimed at evaluating patterns of maturation stress on eucalypt plantation trees and their relation with growth, with a focus on tangential stress evaluation. M ...

- Abstract:
- ... CONTEXT : Natural regeneration with broadleaved species and reforestation with coniferous trees are two widely practiced forest regeneration strategies after timber harvesting. They lead to different tree species composition and may cause different understory biodiversity, but the effects on ground bryophyte composition and diversity are not well-known. AIMS : We tested whether natural regeneratio ...

CONTEXT : Warmer temperatures and anthropogenic N depositions are altering soil nutrient cycles and plant nutrition worldwide and are projected to rise dramatically in the future, particularly at the high latitudes. How much will such alterations affect symbiotic organisms such as ectomycorrhizae (ECM)? AIMS : The aim was to investigate the short-term effects of warmer soil temperatures and N-enri ...

AIM : The objective of this work is to evaluate the effect of first thinning on growth and cone production in an artificially regenerated stand in order to determine optimum intensity. METHODS : A thinning trial was installed in 2004 to compare two thinning r ...

So far, little is known about the waterlogging tolerance of boreal tree species during their winter dormancy. AIM : The aim was to quantify the degree of waterlogging tolerance of 1-year-old dormant Norway spruce (Picea abies (L.) Karst.) seedlings. METHODS : The seedling ...
