Drought stress can profoundly affect plant growth and physiological vitality, yet there is a notable scarcity of controlled drought experiments focused on herbaceous species the forest understory. In this study, we collected seeds from five forb four graminoid growing in temperate understory Czech Republic. These were germinated under glasshouse conditions subjected to moderate for weeks. We assessed biomass partitioning, stomatal leaf morphology, gas exchange, minimum conductance (gmin),...
Abstract Drought stress can profoundly affect plant growth and physiological vitality, yet there is a notable scarcity of controlled drought experiments focused on herbaceous species the forest understorey. In this study, we collected seeds from five forb four graminoid common in European temperate forests. Seeds were germinated under glasshouse conditions subjected to moderate for 5 weeks. We assessed biomass partitioning, stomatal leaf morphology, gas exchange, minimum conductance ( g min...
Monoculture forests formed by Fagus sylvatica L. belong to one of the most sensitive forest ecosystems, mainly at low altitudes. Cultivation this species in mixed stands should reduce its sensitivity drought vegetation period, which is why we researched water balance pure-beech (i.e., monoculture) and beech–oak–linden mixed) forest. This research was carried out Drahanská vrchovina Czech Republic period 2019–2021. The total precipitation measured, together with partitions throughfall...
Abstract The extreme drought events in the last years caused high mortality amongst European beech (Fagus sylvatica L.) across Central Europe. Thus, knowledge of response to and its ability recover xylem leaf functions after release is needed better understand survival. In this study, changes function, gas exchange, chlorophyll fluorescence morphology saplings during recovery phases were assessed. Beech exposed three different watering intensities—well-watered (W), moderately stressed (M)...
Knowledge of the quantity woody biomass poplar short-rotation coppice (SRC) on agricultural land is a basic tool for management decisions like rotation length, volume production and financial balance sheet economic activities. The expansion SRC requires fast, reliable, easily applicable cheap method estimating yield, but existing methods are based labour-demanding lengthy measurements all shoots per tree. objective this study was to verify novel rapid estimation that uses averaged attributes...
Abstract Several studies have shown that petiole xylem structure could be an important predictor of leaf gas exchange capacity, but the question how relates to under different environment conditions remains unresolved. Moreover, knowledge amount and structural variation exists within a single species is also limited. In this study, we investigated intraspecies coordination traits in 2-year-old seedlings Ulmus laevis Pall. well-watered drought conditions. It was found all studied elm were...
Drought and high evapotranspiration demands can jeopardise trees shrubs in windbreaks habitat corridors, where they are more exposed to the effects of extreme weather than forest. This study utilised chlorophyll fluorescence assess how leaf-level physiological processes 13 woody species typically planted Czech corridors responded naturally occurring drought their ability recover after rain. Linear electron flow (LEF) only weakly drought, indicating levels photorespiration. Trees increased...
Despite the great diversity in leaf structural and physiological traits, traits appear to be coordinated with function. It was observed that petiole xylem structure is an important predictor of gas exchange capacity, yet only a few studies have dealt directly question how relates exchange. An understanding amount variation exists within single species also limited. In this study, we investigated intraspecies coordination two-year old seedlings Ulmus leavis Pall. during optimal drought...
There is an urgent need to better understand the processes underlying trees resistance and resilience drought as a prerequisite for adapting climate change. In this study, effect of episodic long-term on physiology European white elm saplings, well rates at which their physiological traits recover after were identified. Elm saplings responded sensitively stress leaf water potential, followed by net photosynthesis stomatal conductance most sensitive traits. The normalized difference vegation...
<p>The density of forest canopy is affecting understory light conditions as well soil water availability. Trees either suppress the herbaceous species by competition for resources or help them to cope with increased climatic warming shading. Nevertheless, little known about × interaction on performance. In shaded environments, such in understory, energy needed stomatal opening may not be entirely offset imminent carbon gain, which give a partial advantage...
<p>Dense forest canopy influences understory microclimate by lowering the air and surface temperatures. It can mitigate adverse effects of global climate change in communities. On other hand, low light availability dense forests is main constraint for species photosynthesis. And resulting lack carbohydrates may make herbs more vulnerable to increasing drought induced change. Here we assessed survival ecophysiology two morphologically similar but physiologically rather...
Droughts negatively affect tree vitality, growth and mortality in temperate forests. Appropriate forest management may help mitigate these adverse effects. One such technique is coppicing, which increases a stand’s drought resistance compared to high forests, but the underlying mechanisms are not well explored. Here, we aimed deepen our mechanistic understanding of performance sessile oak ( Quercus petraea ) response stress two silvicultural systems (high coppice) stages ontogeny (mature...
