Naturalization of landscaping woody plant, Magnolia obovata potentially invasive species.

摘要: Magnolia obovata, a tree species native to Japan, is traditional landscaping that has also been introduced various countries. M. obovata individuals have recently emerged in non-planting areas Korea, prompting us investigate its distribution by establishing Dosolsan an urban forest of Daejeon City as the target site. In order determine naturalization, study explored status population growth examining diameter at breast height individuals, and diminution quotient was calculated. Cores trees were collected, age estimated regression analysis. Reproduction possibility analyzed verifying flower-blooming fruit-bearing. Spontaneous colonization investigated other potential sites which different location environment, respectively. The showed reverse J-shaped curve, ≥1.8. composed generations, thus confirming population. distributed grew flowered normally, followed normal life cycle. same phenomenon observed planting areas, residual forests or rural alluvial islands, mountain forests. continuous spread new ecosystems may be attributable long-term birds, relatively fast growth, maturity time. Investigations on naturalization well countries, are warranted.
