We measured the mass, viability, and physical dormancy of half-year-old seeds in five in-situ collected seed lots, while potential seed longevity (i.e., seed bank type) was estimated from repeatedly germinating subsamples from four ex-situ collected seed lots for 3–8 years. Plant survival, flowering, and seed production were studied in different light-, irrigation-, and competition conditions in a botanical garden experiment. We found that 1) half-year-old seeds have a high germination capacity (78–100%), 2) and high level of physical dormancy (72–100%) in all examined Hungarian populations, and 3) the seeds can preserve their germination capacity for more than five years, although their viability sharply decreases, probably falling below 10% within ten years, when they are stored at room temperature. The results of the botanical garden experiment suggested that 1) the species is annual, not biennial; 2) it shows strong sensitivity to precipitation and low competitiveness for water; and 3) it can produce hundreds of seeds even in suboptimal (dry or shady) conditions. Although the species was found to be well-adapted to a temporally heterogeneous environment, its future vulnerability can increase depending on the duration of dry seasons. Further investigation of genetic diversity and soil seed bank is needed to estimate the actual vulnerability of the species while strengthening the populations through seed sowing, and additional vegetation control in the habitats is suggested.}, year = {2023}, eissn = {1314-3301}, pages = {121-147}, orcid-numbers = {Sőth, Ármin/0000-0002-6417-3168; Deák, Balázs/0000-0001-6938-1997; Valkó, Orsolya/0000-0001-7919-6293; Nagy, János György/0009-0005-3854-0840} } @misc{MTMT:33684852, title = {Előzetes adatok magyarországi tőzegmohalápjaink vízkémiai felméréshez}, url = {https://m2.mtmt.hu/api/publication/33684852}, author = {Dudás, János and Nagy, János György}, unique-id = {33684852}, year = {2022} } @CONFERENCE{MTMT:32559541, title = {A tőzegeper (Comarum palustre) új telepített állománya az Őrségben}, url = {https://m2.mtmt.hu/api/publication/32559541}, author = {DUDÁS, János and Szépligeti, Mátyás and Nagy, János György}, booktitle = {XIII.

We aimed to examine the impact of elevation on the morphological and reproductive characteristics of Cephalanthera rubra in four different altitudes in Hungary: in a lowland oak forest (103 m), and in the beech forests of the Bükk-mountains (361 m, 533 m, 657 m). We counted the number of leaves, flowers, and fruits, and measured the height of each plant with the length and width of all leaves. Linear, negative binomial, and quasipoisson regressions were used to compare the populations. Our study has shown that the lowland and mountain populations of C. rubra are sharply different regarding their life history strategy and reproductive success, and altitudinal effects can be found only in the mountain populations. The number of flowers depends strongly on the vegetative production (height and leaf area) of the plants, but at the same time, the area that facilitates greater vegetative production-possibly because it also facilitates species with better competitiveness, and it is less favorable to its mimicked partners-were less beneficial in terms of fruit production.}, year = {2019}, eissn = {1785-0037}, pages = {5619-5639}, orcid-numbers = {Gilián, Lilla Diána/0000-0002-2839-9346} } @misc{MTMT:30603248, title = {In vitro propagation of Himantoglossum adriaticum in Hungary}, url = {https://m2.mtmt.hu/api/publication/30603248}, author = {Gilián, Lilla Diána and R.
