“…Plant conservation requires deeper knowledge about the life cycle of plants. Seed germination is an important stage, and this is why the germination characteristics of rare and endemic plants have become important in recent years [27][28][29][30]. There is a need for knowledge associating the biology and habitat characteristics of threatened or endemic plants in order to develop guidelines for their conservation [31][32][33].…”

M. bourgaei Baker is an endemic plant that grows in Türkiye. It has the potential to be an ornamental plant, so it is important to know its germination characteristics and seed morphological characteristics. We evaluated the effects of moist chilling (3 to 12 months) and application of gibberellic acid (GA3) (250 to 1000 mg/L−1) on seed germination under two different light regimes (light phase and dark phase) and four temperature regimes (20, 20/10, 25/15, and 15/10 °C). Seeds were collected from the subalpine belt of Mount Uludağ at an altitude between 2200 and 2300 m. M. bourgaei seeds were dormant and reached the highest germination percentage after 12 months of moist chilling. GA3 applications only have a limited effect on the breaking of dormancy in most cases. Maximum germination of 28 percent was obtained by the GA3 application of 1000 mg/L under dark phase with incubation at 15/10 °C. Scarification with sulfuric acid did not result in any germination. Seed germination of above 80 percent was obtained after 6 months of moist chilling and above 90 percent after 9 and 12 months of moist chilling. Intermediate physiological dormancy was determined as the type of dormancy. Our findings on seed germination and dormancy characteristics of M. bourgaei, which is an endemic alpine meadow plant, will contribute to the protection and development of the germplasm of this species.

A b s t r a c tA study of the life-history traits and seedling recruitment in small and isolated populations of a rare clonal species, Dianthus superbus L., was carried out in the years 2011-2012 in Kraków-Kostrze (Southern Poland). Observations were conducted in unmanaged Molinietum caeruleae meadows situated along the successional gradient. The patch representing the initial stage of succession (P1) was dominated by small species creating delicate erect or procumbent stems, the patch representing the temporary stage of succession (P2) was prevailed by large-tussock grasses and tall-growing macroforbs, while the patch representing the terminal stage of succession (P3) was partly overgrown by bushes and trees. The number of generative shoots, flowers, fruits and seeds of Dianthus superbus L. diminished gradually from P3 via P2 to P1. The increase in abundance of generative shoots and flower number in the vicinity of tall plants contributes to increased visibility of inflorescences and may enhance the chances for nocturnal pollinator visits. A significant production of fruits and seeds in competitive neighborhood may augment the chances for successful dispersal and colonization of new, perhaps more favorable habitats. The recruitment of seedlings occurred only in artificially created gaps in plant canopy and litter. The appearance of seedlings and their survivorship were better in P1 than in P2 and P3. Such a phenomenon might be due to the locally rising water level and the diminishing amount of light reaching to the soil area along the successional gradient.Concluding, it should be asserted that a low production of generative shoots, flowers, fruits and seeds by the population of Dianthus superbus L. established in the patch dominated by small meadow species is compensated by the highest seedling recruitment and their survival. On the other hand, a substantial production of generative structures is not sufficient to ensure the persistence of populations in meadows in advanced stages of secondary succession.
