“…Our coeffi cient correlation analysis between each morphological seed variable showed agreement with the general tendency of relationships between most of the characters (Cervantes et al 2016, Chambers and Macmahon 1994, Ehrenberg et al 1955, Greene and Johnson 1993.…”

“…Th is peat bog population has seeds with lower mass, longer shape associated with shorter and slimmer wings. In literature, the size and shape of the seed are described as a feature which can easily change, not only with the climatic conditions of the year but even with the diff erence in cone size, the number of seeds per cone and the position within the cone (Ehrenberg et al 1955). Th e number of seeds in each cone sampled was not determined in our study, but our previous results suggested signifi cant diff erences rather in structure (by higher values of length, width, and thickness of apophysis) than in the size of cones from peat bog populations (Köbölkuti et al 2017).…”

“…In Pinus, variations can mainly be attributed to the infl uence of the mother tree on the genetic composition of the seed coat and gametophyte, and to environmental conditions during seed development (Surles et al 1993). Th e size of the seed easily changes, not only with the climatic conditions of the year but even with the diff erence in cone size, the number of seeds per cone and the position within the cone (Ehrenberg et al 1955). As a broad generalisation, it appears that taxa associated with stressful environments have smaller cones (Richardson and Rundel 1998) and it is intuitive to expect the largest seeds in the largest cones, but Keeley and Zedler (2000) showed, that correlation between cone size and seed size is poor.…”

“…During adaptation, certainly there are diff erences in genetic characters with regard to juvenile growth. To a large extent, however, the diff erences can be referred to casual characteristics of the seeds, embryo development, endosperm state, seed weight and in maturity in relation to the climate (Ehrenberg et al 1955).…”

Seed morphology and seed germination power can be useful to characterise genotypes in natural populations. Measures of size and shape, their correlation and relationship with the germination capacity may be either the result of developmental programs or the response to a specifi c environmental condition. At the fi rst instance, the development of the seed is highly infl uenced by the environment, its size and weight being strongly determined by the genotype and the environmental factors acting on the mother tree. Secondly, the survival of plants and their populations in fragmented landscapes strongly depends on their dispersal potential, seeds having specifi c morphological adaptations that infl uence their movement towards suitable germination microsite. Finally, germination and characteristics of juvenile seedlings are also infl uenced through seed morphology, inducing a successful distribution of the species. In our study we've focused on quantifying variation in seed traits and germination power among and within marginal populations of Pinus sylvestris L, considering the type of habitat. Discriminant function analysis showed signifi cant diff erentiation of populations growing in peat bogs. Seed length, wing length and the percent of germination were the most useful traits to identify seeds of peat bog origin that are most probably adapted to the bog specifi c environment.

Silver firs (Abies alba Mill.) of natural origin occurring in the Belorussian part of the Białowieża Primeval Forest constitute an enclave situated 120 km to the north-east of a dense fir stand in the Polish part of the forest. In order to protect this population a reserve called ‘Tisovik’ was established. In this study, plant communities occurring in the ‘Tisovik’ reserve were described and its fir population (20 trees) was characterised in terms of its genetic structure.
