The effect of site conditions and type of ramet clusters on sexual and asexual ramets of Solidago × niederederi (Asteraceae)

Spontaneous hybrids between alien and native plant species are taxa they threaten biodiversity due to their high competitive ability or introgression. Thus, we tested the effect of soil conditions, elevation type ramet clusters (clonal clumps shoots) on sexual asexual ramets Solidago × niederederi , a hybrid invasive S. canadensis virgaurea . We also relationships size habitat conditions in its parental species, based ten sites NE S Poland, respectively. The occurred mineral soils with wide range textures (sand, loamy sand, sandy loam, silty loam loam) pH (from strongly acidic slightly alkaline). Sexual dominated populations, while total number was highest mixed clusters. cluster site interaction had significant length biomass populations. Moreover, found taxon case synflorescences (capitula arranged panicles). Based shoots synflorescences, abilities may be more less similar albeit depending conditions.
