The edaphic factor and orchids: Gymnadenia conopsea from contrasting geologies in the Central Balkans.

Two different strategies for the distribution of macro- and trace elements can be observed in the terrestrial orchid Gymnadenia conopsea. Most trace elements are not translocated to the above-ground parts, whereas for macro-elements the trend was reversed, with the highest accumulation in the distal parts of the plants. Edaphic stress is one of the main factors affecting plant fitness, but it is still poorly understood, even in rare plants such as orchids.

Effects of the Salt Stress Duration and Intensity on Developmental and Physiological Features of the Moss .

The two accessions of the polytrichaceous moss species , namely German and Serbian genotypes, were subjected to salt stress, aiming to study the species' developmental and physiological features. Various concentrations of sodium chloride were applied to an axenic culture of the two moss genotypes, and the growth parameters as well as physiological feature changes were followed. As inferred by the morpho-developmental parameters and survival index, the Serbian genotype showed higher resistance to salt stress as compared to the German one.

Effects of Cesium on Physiological Traits of the Catherine's Moss Hedw.

Mosses are proven bioindicators of living environments. It is known that mosses accumulate pollutants from precipitates and, to some lesser extent, from the substrate. In this study, the effects of cesium (Cs) on the physiological traits of acrocarp polytrichaceous Catherine's moss ( Hedw.

Analysis of the Qualitative and Quantitative Content of the Phenolic Compounds of Selected Moss Species under NaCl Stress.

The response to salt stress analysed by quantitative and qualitative analyses in three selected moss species was studied. Non-halophytic funaroid and two halophytic mosses, funaroid and pottioid were exposed to salt stress under controlled in vitro conditions. The results clearly showed various phenolics to be present and included to some extent as a non-enzymatic component of oxidative, i.

The occurrence of K and Cs radioactivity in mosses during 2015-2019 in the Djerdap National Park (E. Serbia).

The radiation status of the national park (NP) Djerdap (Eastern Serbia) is characterized using bioindicators (mosses). Mosses (16 species, 156 samples) were collected randomly within the area of NP Djerdap during the month of June, periodically from 2015 to 2019. Samples were collected in the regions of Dobra, Donji Milanovac, and Tekija.

The Conservation Physiology of Bryophytes.

An introduction to the conservation physiology of bryophytes is given. The insights into the problems, solutions and examples of the physiological approach to conservation within bryophyte representatives are discussed. The significance of experimental treatments of bryophytes is highlighted.

Morpho-Physiological and Molecular Evaluation of Drought and Recovery in Grown Ex Vitro.

This study was carried out to examine the drought effect on development, physiological, biochemical and molecular parameters in grown ex vitro. Experiment design included three treatments: Control plants-grown under optimal watering (35%-37% of soil moisture content), drought-stressed plants-non-irrigated to reach 15% and 5% of soil moisture content and recovery plants-rehydrated for four days to reach optimal soil moisture content. Drought reduced fresh weight, total leaf area, as well as dry weight of shoots.
