In Verzy forest (near Reims, France), seeds were sampled from some tortillard beeches (Fagus sylvatica L. var. tortuosa Pépin) after free pollination. After a dormancy breaking treatment performed in laboratory, seeds were sown in nursery and seedlings were cultivated for 4 years. The purpose of this study is to examine the fertility of tortillard beech and the occurrence of its phenotype during the first years of development. According to our experimental conditions, full and empty seed ratios, germination rate, and seedling annual survival rate were not significantly different from those reported for the European beech in literature. Among 486 tortillard maternal descendants, after 4 years, 25% of the individuals showed a special shape, characterized by reiterations, and could be considered as "tortillards". This phenotype appeared progressively during the second year of seedling development. The number of tortillards increased from one year to the next and their typical shape became more pronounced until they were 4 years old. These results show that the tortillard variety is no less fertile and vigorous than the European beech. Key words: Fagus sylvatica var. tortuosa, morphology, growth, fertility, strength.

Global change increases the risk of extreme climatic events. The impact of extreme temperature may depend on the tree species and also on the provenance. Ten provenances of Fagus sylvatica L. were grown in a common garden environment in Belgium and subjected to different temperature treatments. Half of the one year old seedlings were submitted to a high thermal stress in the spring of the first year, and all plants were exposed to a late spring frost in the second year. The high-temperature treated plants displayed reduced growth in the first year, which was fully compensated (recovery with exact compensation) in the second year for radial growth and in the third year for height growth. Frost in the spring of the second year damaged part of the saplings and reduced their growth. The frost damaged plants regained the pre-stress growth rate one year later (recovery without compensation). The high temperature treatment in the first year and the frost damage in the second year clearly influenced the phenological responses in the year of the event and in the succeeding year. Little population differentiation was observed among the provenances for growth and for phenological responses. Yet, a southern provenance, a non-autochthonous provenance (original German provenance that was planted in Belgium about a century ago) and a more continental provenance flushed earlier than the local Atlantic provenances in the year of the frost event, resulting in more frost damage. Some caution should therefore be taken when translocating provenances as an anticipation of the predicted climate warming.

Mg Content

The paper informs of N, P, K, Ca and Mg-contents in the selected organs (tissues) of 4-year old Norway spruce (Picea abies /L./ Karst.) and 3-year old European beech (Fagus sylvatica L.) transplants after two years of Mg fertilization (100 kg Mg.ha−1.year−1) in the form of magnesium sulphate, and N fertilization (100 kg N.ha−1.year−1) in the form of ammonium sulphate. Analyses of buds, needles/leaves, bark and wood of above-ground part, fine roots (≤ 1 mm) and small-diameter roots (> 1 mm) showed that the greatest amounts of uptaken nutrients are in both tree species stored in assimilatory organs and in buds. The increased supply of nitrogen showed most in small-diameter roots (spruce), and in root-wood, and wood of stem and branches (beech). The two species responded to the increased supply of magnesium by increasing the bioelement content in root-wood and in fine roots. The increase of Mg-content in leaves occurred only in the second year of the fertilization.

European beech (Fagus sylvatica L.) trees are becoming vulnerable to drought, with a warming climate. Existing studies disagree on how radial growth varies in European beech in response to droughts. We aimed to find the impact of multiple droughts on beech trees’ annual radial growth at their ecological drought limit created by soil water availability in the forest. Besides, we quantified the influence of competition and canopy openness on the mean basal area growth of beech trees. We carried out this study in five near-natural temperate forests in three localities of Germany and Switzerland. We quantified available soil water storage capacity (AWC) in plots laid in the transition zone from oak to beech dominated forests. The plots were classified as ‘dry’ (AWC < 60 mL) and ‘less-dry’ (AWC > 60 mL). We performed dendroecological analyses starting from 1951 in continuous and discontinuous series to study the influence of climatic drought (i.e., precipitation-potential evapotranspiration) on the radial growth of beech trees in dry and less-dry plots. We used observed values for this analysis and did not use interpolated values from interpolated historical records in this study. We selected six drought events to study the resistance, recovery, and resilience of beech trees to drought at a discontinuous level. The radial growth was significantly higher in less-dry plots than dry plots. The increase in drought had reduced tree growth. Frequent climatic drought events resulted in more significant correlations, hence, increased the dependency of tree growth on AWC. We showed that the recovery and resilience to climatic drought were higher in trees in less-dry plots than dry plots, but it was the opposite for resistance. The resistance, recovery, and resilience of the trees were heterogeneous between the events of drought. Mean growth of beech trees (basal area increment) were negatively impacted by neighborhood competition and positively influenced by canopy openness. We emphasized that beech trees growing on soil with low AWC are at higher risk of growth decline. We concluded that changes in soil water conditions even at the microsite level could influence beech trees’ growth in their drought limit under the changing climate. Along with drought, neighborhood competition and lack of light can also reduce beech trees’ growth. This study will enrich the state of knowledge about the ongoing debate on the vulnerability of beech trees to drought in Europe.
