“…Pliszko [5] and references therein), are diploid, karyologically uniform and have a somatic chromosome number 2n = 18 [23]. Solidago ×niederederi described from many localities in Europe [3][4][5][6][7][8][9][10][11][12][13] and found in one locality in Poland [5] is most likely diploid with the same chromosome number 2n = 18 as putative parental species and is partly or completely sterile [4,6]. The hybrid nature of specimens from Poland was estimated from morphological features [5].…”

“…In Europe, Solidago ×niederederi Khek, a natural hybrid between the alien S. canadensis L. and the native S. virgaurea L. [3][4][5] has rarely been recorded in Austria, Denmark, Sweden, Norway, the United Kingdom, Germany, and in Poland [3][4][5][6][7][8][9][10][11][12][13]. Its occurrence is undoubtedly an indirect result of naturalization and invasion of North American S. canadensis [14,15].…”

Reduced pollen viability and achene development in Solidago ×niederederi Khek from Poland

et al. 2014

Pollen and achene characters of natural interspecific hybrid Solidago ×niederederi Khek were analyzed and compared with putative parental species S. virgaurea L. and S. canadensis L. to estimate the level of disturbances in generative reproduction resulting from its hybrid nature. Pollen viability (stainability) of Solidago ×niederederi from one newly discovered locality in NE Poland was evidently reduced to ~65% in both viability tests (acetocarmine and Alexander). The diameter of viable pollen (median 21.11 µm) fell between S. canadensis (median 19.52 µm) and S. virgaurea (median 23.48 µm). Both parental species produced normally developed achenes with high frequency (~90%) whereas in the hybrid, the seed set was dramatically low (6%). The results clearly indicated that sexual reproduction of hybridogenous taxon S. ×niederederi is disturbed, and its potential impact as an invasive species depends mainly on vegetative propagation.

“…This hybrid was described in 1905 based on specimens from Austria (Khek 1905) and new records of S. ×niederederi were absent probably until 1920, when it was found in Austria (Pliszko 2015). Since the middle of the 20 th century hybrid plants started to emerge in various European countries: Austria (Melzer 1984, Essl & Rabitsch 2002, France (Kerguélen 1999), Sweden and Denmark (Nilsson 1976), Britain (Stace 1991), Norway (Sunding 1989), Germany (Otto et al 2005, Bleeker et al 2007, Poland (Pliszko 2013), Lithuania (Karpavičienė & Radušienė 2016), etc. Though in many European countries S. ×niederederi is reported as rare, it is increasingly frequent and in some localities abundant in Lithuania.…”

“…For example, an extent of hybridization between native and alien species has been evaluated in Germany. The study revealed that 75 hybrids have been already registered and 59 further hybrids can be detected as both parental species occur in the country (Bleeker et al 2007).…”

“…Nowadays, it is an impact mechanism taken into consideration in the classifi cation of alien species (Blackburn et al 2014). Spontaneously occurring hybrids between alien and native plants have been well-documented (Vilà et al 2000, Daehler and Carino 2001, Bleeker et al 2007, Lehman et al 2014, Stace et al 2015, and according to Pyšek et al (2004) they must be understood as alien plant species.…”

-The paper provides data on the fl oristic composition of vegetation in anthropogenic habitats suitable for Erigeron × huelsenii, a spontaneous hybrid between the alien E. canadensis and native E. acris s. str. The study is based on 21 phytosociological relevés (vegetation plots) of 5×5 m size made in 2013-2014 in the Polish part of the Lithuanian Lakeland (north-eastern Poland) using the Braun-Blanquet method. The plots were taken on a roadside verge, a roadside slope, in abandoned sand and gravel pits, and on arable fi elds with grass-legume mixtures. There are 91 species of vascular plants, four species of bryophytes, three species of lichens, and one species of cyanobacteria. Vegetation is represented by populations of species typical of plant communities from the classes Stellarietea mediae, Artemisietea vulgaris, Koelerio-Corynephoretea, FestucoBrometea and Molinio-Arrhenatheretea. Two fl oristic groups recognized from hierarchical cluster analysis and principal component analysis correspond with ruderal and segetal habitats. The study reveals that arable fi elds with grass-legume mixtures on sandy soils can be very suitable for E. × huelsenii.
