“…The average PIC (0.626) and genetic diversity (He = 0.65) values were similar to those reported by Lepais and Bacles (2011) for Scottish A. glutinosa samples (average PIC = 0.68; average He = 0.69) and the He value was consistent with mean values from microsatellite data obtained for Irish, Scottish, and French populations (Cubry et al 2015; He = 0.64) and for Northern Irish populations (Beatty et al 2015;He = 0.66). These values were consistent with the mean values from Sample size (N), total number of alleles (Nat), mean number of alleles per locus (Nam), allelic richness (Â), observed heterozygosity (Ho), expected heterozygosity (He) Fig.…”

“…Using SSR markers, Lepais et al (2013) showed a strong distinctiveness of Moroccan populations of A. glutinosa in the rear-edge distribution margins of the species. Recently, two studies using SSR markers have shown high levels of genetic diversity and very little differentiation between Irish A. glutinosa populations (Beatty et al 2015;Cubry et al 2015). Similarly, a recent study based on population genomics and conventional provenance trials conducted mainly in Flanders in Belgium showed little differentiation in adaptative traits among populations (De Kort et al 2014).…”

Due to its beneficial effects on river ecosystems, black alder (Alnus glutinosa) is one of the tree species selected for planting on riverbanks in the cross-border area encompassing Wallonia in Belgium, Lorraine in France, and Luxembourg. The preservation of this species, however, is threatened by an invasive pathogen that particularly targets and kills young alder individuals. The objectives of this study were to characterize the genetic diversity and the genetic structure of A. glutinosa at this local level with the aim of assisting the conservation and replanting strategies and to determine if a germplasm collection comprising individuals from the same cross-border area captures the diversity present in the region. Nuclear simple sequence repeat (SSR) and chloroplastic DNA (cpDNA) markers were used to analyze four local wild populations and the germplasm collection which is representative of two river catchments and six legal provenance regions. Three populations distant from the studied area were also included. A panel of 14 nuclear SSR loci revealed high allelic diversity and very low differentiation among wild populations (mean F ST = 0.014). The germplasm collection displayed a range of alleles that were representative of the different populations, and no significant differentiation between the germplasm collection and the local wild populations was observed, making this collection, as far as allelic diversity is concerned, suitable for providing trees for riverbank replanting programs. Using SSR markers, various statistical approaches consistently indicated the lack of a significant geographical structure at the level of the river catchments or provenance regions. In contrast, two cpDNA haplotypes were detected and displayed a cross-border geographically structured distribution that could be taken into account in defining new cross-border provenance regions.

“…Levels of inbreeding, measured as F IS (mean F IS = 0.121), were higher than those reported for ash (mean F IS = 0.067; Beatty et al 2015a), alder (mean F IS = 0.078; Beatty et al 2015b) and hawthorn (mean F IS = 0.047; Brown et al 2016). The levels of F IS observed in hazel are somewhat surprising, given that the species shows dichogamy and has sporophytic self-incompatibility (Thompson 1979), but records of self-fertilization have been reported in hazel (Persson et al 2004) and partial selfcompatibility observed in a few cultivars (Mehlenbacher and Smith 2006;Mehlenbacher 2014).…”

“…In comparison with studies on other broadleaved tree species from Ireland that utilized microsatellites, hazel has the highest level of genetic diversity to date (mean H E = 0.828) compared to hawthorn (mean H E = 0.803; Brown et al 2016), ash (mean H E = 0.765; Beatty et al 2015a), sessile oak (mean H E = 0.720; Beatty et al 2016), pedunculate oak (mean H E = 0.714; Beatty et al 2016) and alder (mean H E = 0.663; Beatty et al 2015b). Levels of inbreeding, measured as F IS (mean F IS = 0.121), were higher than those reported for ash (mean F IS = 0.067; Beatty et al 2015a), alder (mean F IS = 0.078; Beatty et al 2015b) and hawthorn (mean F IS = 0.047; Brown et al 2016).…”

“…Recent genetic studies on British and Irish trees suggest that Bseed zones,^areas with similar ecological, geographical and climatic features (Herbert et al 1999) such as those drawn up by the Forestry Commission, may not be necessary for ash (Sutherland et al 2010;Beatty et al 2015a), alder (Beatty et al 2015b) and hawthorn (Brown et al 2016), due to genetic homogeneity. As there is a lack of information about the level of genetic diversity at a similar scale for hazel, we used highly polymorphic microsatellite markers (Powell et al 1996) to elucidate levels and patterns of diversity in natural populations of this key native woodland species.…”

Hazel (Corylus avellana) has been a key species in European woodlands throughout the Holocene (10 KYApresent). Like many tree species, it is increasingly under threat from climate change, habitat loss and fragmentation, invasive species and emergent pathogens. As knowledge of the genetic structure of natural populations of trees is vital for managing these threats, as well as an essential basis for selection of material for replanting and restocking, we analysed levels and patterns of genetic diversity in the species at a range of spatial scales using high-resolution microsatellite markers. Our findings indicate that hazel populations exhibit high levels of genetic diversity along with low levels of population differentiation, suggesting extensive gene flow. Fine-scale genetic structuring was observed in some of the woodlands studied, probably resulting from restricted dispersal of the heavy nuts produced by the species. This, coupled with higher levels of pollen-mediated gene flow, resulted in a weak but significant pattern of isolation by distance. These results suggest that replanting following potential loss of hazel populations may not necessarily require the use of material from the same locality and mirror findings in other broadleaved tree species from the same area.

Variability of cone parameters and scale morphology in the black alder (Alnus glutinosa L.) in the context of seed extraction

2019

In this paper, the results of research on the variability of black alder cones (Alnus glutinosa L.) ware presented. The research was carried out for two, significantly different, batches of cones. Basic size parameters and mass were measured. The shape of the cone was determined, and it was described with the fourth-degree polynomial. The surface area and volume of the cone were calculated using the forming curve and formulas for solids: barrel and cylinder. The parameters of cones-shape surface area and volume-were analyzed. It was found that for alder cones (from the researched origins), the average volumes calculated from the barrel formula are 1701 mm 3 and 1162 mm 3 , and the areas calculated from the cylinder formula are 807 mm 2 and 597 mm 2. The structure of the inner and outer sides of scales was examined using a scanning electron microscope. Using the MultiScanBase v. 18.03 program, the elements of husk structure that could affect the efficiency of seeds extraction were measured. The results of the research can be used to program the process of seeds extraction from alder cones in commercial installations.
