Abstract EN
Morphological and functional leaf traits like leaf toughness and nutrient content are essentially influenced by the environment, especially through light and climatic conditions.
Varying light conditions have been identified as a significant predictor for the variation of many leaf traits.
However, the leaf acclimation to light is suggested to be of secondary importance.
The aim of the experimental study was to analyse environmental effects (microclimate and soil moisture), which are present in upper canopies of forest stands, on leaf traits of juvenile Fagus sylvatica L.
(European beech; Fagaceae), Acer pseudoplatanus L.
(sycamore maple; Sapindaceae), and Carpinus betulus L.
(hornbeam; Betulaceae).
The experimental design managed to imitate two distinct microclimates causing different temperature and air humidity conditions.
Furthermore, the irrigation treatment with different levels of applied water caused distinct soil moisture conditions in the trial pots.
As a result of the treatments, leaves of C.
betulus showed a tendency of decreased specific leaf area (SLA) caused by the treatment with warmer and drier microclimate.
The environmental effect on SLA was even stronger with lower soil moisture conditions.
Chlorophyll content showed lower values in treatments with higher soil moisture conditions in both greenhouses for F.
sylvatica and A.
pseudoplatanus.
The trends are in accordance with combined effects of temperature, air humidity, and soil moisture on SLA, and increased leaf chlorophyll content caused by slight drought stress.
Plants in the greenhouses were exposed to full sunlight indicating a microclimatic environment comparable to upper canopies in forest stands.
The comparable SLA and chlorophyll content between leaves of mature F.
sylvatica trees in upper canopies and juvenile trees of the greenhouses suggest similar environmental conditions instead of ontogenetic effects that are responsible for the formation of leaf trait characteristics.
