Abstract

V magistrskem delu smo mikroskopsko identificirali in opisali 6 invazivnih lesnih vrst iz območja Mestne občine Ljubljane in sicer: Thunbergov češmin (Berberis thunbergii L.), Davidovo budlejo (Buddleja davidii Franch.), sivi dren (Cornus sericea L.), Maackovo kosteničevje (Lonicera maackii (Rupr.) Maxim.), lovorikovec (Prunus laurocerasus L.) in octovec (Rhus typhina L.). Material za raziskave smo pridobili v okviru projekta APPLAUSE. Vseh 6 izbranih vrst je bilo pred posekom dendrološko identificiranih. Izbrane lesne vrste predstavljajo majhen delež v lesni zalogi, saj vse razen octovca nastopajo kot grmovne vrste. Makroskopska identifikacija lesa opisanih vrst večinoma ni mogoča. Poleg dendrološke identifikacije rastline je bolj verjetna mikroskopska identifikacija lesa. Ta je običajno težavna, saj identifikacijski ključi ne vsebujejo naštetih lesnih vrst, ali pa so njihovi opisi pomanjkljivi. V nalogi smo podrobno opisali mikroskopske znake 6 izbranih invazivnih vrst. Podali so tudi predloge za dopolnitev obstoječih kombinacij znakov objavljenih na spletni platformi Inside Wood. Za mikroskopske opise smo uporabili ključ za mikroskopsko identifikacijo lesa IAWA (International Association of Wood Anatomists). Mikroskopske opise smo dopolnili s slikami pridobljenimi s svetlobno mikroskopijo ter elektronsko vrstično mikroskopijo (SEM). SEM fotografije smo uporabili za dopolnitev svetlobno mikroskopskih slik. Iz literature smo zbrali še razpoložljive podatke za splošen opis proučenih vrst in primere njihove uporabe. Kljub splošno negativnemu vplivu invazivnih vrst na naravne ekosisteme, imajo opisane lesne vrste verjetno pomemben potencial za pridobivanje določenih komponent, tudi za medicinsko uporabo, ki bo raziskana v okviru drugih sklopov projekta APPLAUSE.

Secondary title: Wood anatomy of selected invasive alien species
Secondary abstract: In this master thesis, we microscopically identified and described six invasive wood species, all from the city of Ljubljana. The species were: japanese barberry (Berberis thunbergii L.), butterfly bush (Buddleja davidii Franch.), red-osier (Cornus sericea L.), amur honeysuckle (Lonicera maackii (Rupr.) Maxim.), cherry laurel (Prunus lurocerasus L.) and staghorn sumac (Rhus typhina L.). The research material was gathered within the project APPLAUSE. All six chosen wood species were dendrologically identified before they were cut down. The chosen wood species have a small wood stock, as all but Rhus typhina have a form of a bush. That is why macroscopic identification of their wood is difficult. We can only identify the plant by means of dendrology, and perform microscopic wood identification. Such identification is difficult, as the microscopic wood structure of the investigated species is usually not described in the literature. In this thesis the microscopic wood structure of the six selected species is described in detail. Furthermore, some additions are suggested to improve the available descriptions (IAWA features) on the web site of Inside Wood. Our microscopic descriptions are equipped with pictures obtained by the light microscope and scanning electron microscope (SEM). SEM pictures serve as an addition to the ones obtained by light microscopy. For the investigated species we also gathered other available information, including their basic description and uses. Besides a commonly negative influence of the invasive species on natural environments, there exists great possibility to use them and their specific components, for medical purposes. Such potential uses will be researched on a pilot level within other segments of the APPLAUSE project.
