Black poplar (Populus nigra L.) is one of the main woody riparian species in Europe. Because of extensive habitat loss due to river regulations, this species is considered rare and threatened. To analyze genetic diversity and spatial genetic structure, we examined ten nuclear microsatellite loci in a population of very old P. nigra trees growing along the Vistula River in Poland. We found a high level of genetic diversity (H E = 0.792, H O = 0.731, A = 14.7) that was within the range of other natural European P. nigra populations, and our results showed that sexual propagation is the dominant way of reproduction in the studied population, leading to high clonal diversity (R = 0.91). Additionally, we did not detect a spatial genetic structure resulting in a random spatial distribution of genotypes. Individuals from such old and diverse populations have the potential to provide valuable reproductive material for both restoration programs and breeding purposes.

“…Although the expected heterozygosity (H e ) ranged from 0.143 (population B) to 0.187 (population M) and these values were quite similar to the results obtained in other studies using dominant markers (Smulders, 2008;Sochor et al, 2013), they were still lower in comparison to codominant markers (Kikuchi et al, 2011;Lee et al, 2011;Sochor et al, 2013). Nybom (2004) stated that H e of endemic and peripheral populations should be greater than 0.20, but at the same time she pointed out that heterozygosity is lower for species whose seeds disperse and germinate close to maternal plants, which was observed in the studied populations of S. lapponum.…”

“…Seedlings were more often detected in the disturbed area. Smulders et al (2008) and Sochor et al (2013) observed similar results when studying populations of Populus nigra L. and S. daphnoides Vill., which were located on regulated and unregulated riversides. According to Douhovnikoff et al (2005) and Sochor et al (2013), seeds of the abovementioned willow species are characterized by low viability and they germinate in soil that is both moist and rich in nutrients.…”

The main aim of the study was to increase the knowledge on the ecology and biology of the boreal relict Salix lapponum L., an endangered plant in Poland, in order to create an effective protection program. An important aspect was to determine the within-and among-population genetic diversity of the studied species in order to evaluate whether the basic stages of the generative reproduction cycle in the populations were correct. The results confirmed that S. lapponum pollen viability and germinability, for both fresh and stored pollen, were high and so were the seed germination ability and dynamics. All individuals were of sexual origin and the expected heterozygosity was moderate. In spite of this, young individuals were observed in only 1 out of 5 studied populations and it was the most numerous one. Although the genetic diversity among the populations was not very high (Φ PT = 0.12), it accumulated in a quite short period of time, probably during the second part of the 20th century, as a consequence of habitat fragmentation. A lack of gene flow, either by pollen or seeds, may lead to further differentiation of the populations and extinction of the smallest ones. For this reason, preventive measures should be undertaken in order to enlarge the existing populations and to reconstruct S. lapponum populations in selected sites where environmental conditions are the most similar to those preferred by this species.

“…1); clones with more than 45% survival varied from 20 to 28%, the latter in the P. alba collection named AL. This confirmed the large clonal variability of poplar, according to previous reports on Salicaceae (Aravanopoulos et al 1999) and their mainly sexual reproduction (Smulders et al 2008). Survival after the second growth season positively correlated (R 2 =0.75-0.95) with plant size at the end of the first season, thus confirming the evidence that individuals with a larger biomass had a higher probability of survival (Zalesny et al 2005).…”

© iForest -Biogeosciences and Forestry IntroductionMany large areas around the world are contaminated with heavy metals (HMs) and/or organic compounds; most of these have not been remediated due to the high cost and technical drawbacks of currently available technologies. HMs tend to accumulate in soils and aquatic sediments and can enter the food chain leading to the biomagnification phenomenon thereby representing a risk to the environment and to human health (Clijsters et al. 1999). Some essential elements, such as copper (Cu) and zinc (Zn), may be present in soils and waters at potentially toxic levels mainly as a result of agricultural and industrial practices (Ali et al. 2004).Alternative techniques for the clean-up of polluted soil and water, such as the cost-effective and less disruptive phytoremediation, have gained acceptance in recent years (Pilon-Smits 2005, Thewys et al. 2010. Trees have been suggested as suitable for phytoremediation due to their high biomass production (Dickinson & Pulford 2005) and because tree plantations can be multi-purpose (Tognetti et al. 2013). Poplar has many characteristics suitable for phytoremediation: a fast rate of growth, a deep and wide-spreading root system and a metal-resistance trait (Aronsson & Perttu 2001, Di Baccio et al. 2011, Punshon & Dickinson 1997, Sebastiani et al. 2004). In Italy, P. alba (white poplar) and P. nigra (black poplar) populations of the Ticino river valley constitute a hotspot of biodiversity (Castiglione et al. 2009, Fossati et al. 2004. Their genetic variability is being exploited for the selection of genotypes having interesting traits, such as tolerance to pollutants. The remarkable clonal variability of poplar allows to identify genotypes with a greater ability to accumulate/tolerate pollutants including heavy metals , Kopponen et al. 2001, Laureysens et al. 2004, Punshon & Dickinson 1997, Zalesny et al. 2005. Finally, poplar offers the advantage that, being the first "model tree species" whose genome has been sequenced (Tuskan et al. 2004), physiological and molecular mechanisms at the basis of metal tolerance can be more easily investigated at the transcriptomic level (Di Baccio et al. 2011).Plant symbiotic fungi, such as mycorrhizae, and soil bacteria can confer increased tolerance to stress (Gamalero et al. 2009). Arbuscular mycorrhizal fungi (AMF) form associations with the roots of the vast majority of land plants; the fungus colonizes the roots and forms arbuscules within root cortical cells thus improving plant nutrient uptake, especially phosphorus (Smith & Read 1997). Moreover, increasing evidence shows that symbiotic fungi contribute to plant adaptation to multiple biotic and abiotic stresses (Gohre & Paszkowski 2006, Lebeau et al. 2008, Lingua et al. 2002, Liu et al. 2007, Rodriguez & Redman 2008, Smith et al. 2010). In the case of HMs, the beneficial ef- Poplar is a suitable species for phytoremediation, able to tolerate high concentrations of heavy metals (HMs). Arbuscular mycorrhizal fungi (AMF) form symbiotic associatio...
