“…A short description of functional traits used in the analysis is given in Table . Data were obtained from local or Central European databases (LEDA—Kleyer et al ; HUSEED—Peti et al ) and literature sources (Csontos ; Halassy ; Király ; Lhotsky et al ). Where multiple trait data were available, the order of preference was local, national, and then regional data.…”

Community assembly theory is suggested as a guiding principle for ecological restoration to help understand the mechanisms that structure biological communities and identify where restoration interventions are needed. We studied three hypotheses related to propagule limitation, stress-dominance, and limiting similarity concepts in community assembly in a restoration field experiment with a trait-based null model approach. The experiment aimed to assist the recovery of sand grassland on former arable land in the Kiskunság, Pannonian biogeographic region, Europe. Treatments included initial seeding of five grassland species, carbon amendment, low-intensity mowing, and combinations in 1 m by 1 m plots in three old fields from 2003 to 2008. The distribution of 10 individual plant traits was compared to the null model and the effect of time and treatments were tested with linear mixed effect models. Initial seeding had the most visible impact on species and trait composition confirming propagule limitation in grassland recovery. Reducing nutrient availability through carbon amendment strengthened trait convergence for length of flowering as expected based on the stress-dominance hypothesis. Mowing changed trait divergence to convergence for plant height with a strengthening impact with time, supporting our hypothesis of increasing dominance of limiting similarity with time. Our results support the idea that community assembly is simultaneously influenced by propagule limitation and multiple trait-based processes that act through different traits. The limited impact of manipulating environmental filtering and limiting similarity compared to seeding, however, supports the view that only targeting the dispersal and environmental filters in parallel would improve restoration outcome.

“…Baskin and Baskin (1998) also provided information on inducing germination and increasing germination rates for some species, and highlighted that several factors, such as temperature, moisture or salinity have to be tested to identify the most appropriate conditions (Covell et al 1986, Gulzar and Khan 2001, Huang et al 2003, Roberts 1988. To maximise germination rates, the most suitable germination method has to be identified (Peti et al 2017).…”

“…Germination capacity has mostly been studied for agricultural crops, as well as garden and ornamental plants (ISTA). In spite of the increasing involvement of seed traits in ecological research (Hintze et al 2013, Kelemen et al 2015, Török et al 2013, we only found two databases, which contained information about the seed germination capacity of the wild plant species of the Central European flora (SID -RBGK 2018, HUSEED wild - Peti et al 2017). The large international plant trait databases lack such information (LEDA - Kleyer et al 2008, D 3 -Hintze et al 2013.…”

Seeds ensure the survival and dispersal of the majority of vascular plant species. Seeds require species-specific germination conditions and display very different germination capacities using different germination methods. Despite the importance of plant generative reproduction, little is known about the germination capacity of the seeds of the Pannonian flora, particularly under field conditions. Our aim was to reduce this knowledge gap by providing original data on the germination capacity of 75 herbaceous species. We reported the germination capacity of 8 species for the first time. We also highlighted the year-to-year differences in the germination capacity of 11 species which could be highly variable between years. The data regarding the germination capacity of target species, as well as weeds and invasive species, can be informative for nature conservation and restoration projects. Our findings support the composition of proper seed mixtures for ecological restoration and also highlight the importance of testing seed germination capacity before sowing.

“…The germination percentage of about 55 was achieved, which is an acceptable value, considering the long storage period of the seeds. Seed germination is one of the di cult-to measure plant reproductive traits, but it is a trait often used in research (Peti et al 2017). In the short-lived plant species Ensslin et al (2017) found that seed dormancy could be highly variable.…”

Pulsatilla turczaninovii is an important medicinal plant and a material also appreciated by gardeners for its high ornamental value. In this study we assessed the efficiency of reproduction under in vitro conditions of this important representative of the world flora. First, the germination percentage and the following plant development during three growing seasons were assessed, then we tested the possibilities of multiplication by in vitro culture methods. Our study provided new insight on biochemical background of generating adventitious roots in Pulsatilla considered difficult-to-rooting. The germination percentage of studied population reached about 55%. The highest multiplication coefficient of micro-rosettes in tissue culture, amounting to 5.17, was achieved using modified MS medium supplemented with 2.5 mg L-1 2iP and 1 mg L-1 IAA. We proved that in comparison with standard auxin-supplemented rooting medium, the treatment with addition of 1.0 mg L-1 ethylene precursor ACC elevated adventitious rooting by about 20%. The biochemical analyses revealed that total content of soluble sugars was the most impactful biomarker of adventitious rhizogenesis in studied species. Concentration of sugars was positively correlated with rooting efficiency, while the level of phenolic compounds was positively correlated with the root length and their number regenerated per single rosette.
