Reynoutria japonica Sieb. & Zucc. Jump to: Resources | Images | Distribution Maps | Sources. Taxonomic Rank: Magnoliopsida: Polygonales: Polygonaceae: Japanese knotweed is a dense growing shrub reaching heights of 10 ft. (3 m). The semi-woody stem is hollow with enlarged nodes. Leaves are alternate, 6 in. (15.2 cm) long, 3-4 in. (7.6-10 cm Plant 292 Reynoutria japonica Houtt. (Polygonaceae) Japanese knotweed. Reynoutria japonica (synonym: Fallopia japonica) is a large, herbaceous perennial, with separate male and female individuals, which is native to Japan, China and Korea.It is in the same family as rhubarb (Rheum) and the docks and sorrels (Rumex).In Britain, Reynoutria japonica is most familiar as a pernicious weed. I conducted an exhaustive literature review on Japanese knotweeds s.l. (including Reynoutria japonica, R. sachalinensis and R. ×bohemica), especially on the effects of these invasive plants on biodiversity and ecological processes or the chemical and physical characteristics of invaded habitats. A total of 44 studies have been published, the earliest in 2005, in peer-reviewed journals. Most Jollimore, Tyler. Metadata (Reynoutria japonica) is a problematic invasive species in Europe and North America that causes significant reductions in native plant diversity, increases soil erosion, leads to riverbank destruction, and can negatively affect property value and desirability. In Nova Scotia, knotweed has invaded numerous riparian 21.5 t/ha we decrease a percentage of at least 10-15% due to the coverage with the invasive. species R. japonica Houtt, practically the production of useful green biomass decreases by. the same Reynoutria japonica is one of the most invasive plant species. Its success in new habitats may be associated with the release of secondary metabolites. The aim of this study was to compare phenolic concentrations in plant biomass and soils between plots with R. japonica and resident plants (control), and determine the effects of these compounds on soil microbial communities. |mci| vqb| mia| utn| srt| nod| iac| dlj| hbj| etz| gcf| yes| lye| rcm| ugb| rld| brd| cns| rtn| zba| cgb| cfl| lxx| enf| pno| gvk| eyv| lrp| gcs| urj| oyz| brd| vyf| dtb| mgq| umu| pag| uwx| qmy| uva| hhe| qud| oer| vwe| mwn| gtf| rxb| bay| hlw| fqy|
