Abstract

Indijski jagodnjak (Duchesnea indica (Andrews) Teschem.) je trajna zelnata rastlina iz družine rožnic (Rosaceae), ki izvira iz tropskih gozdnih območij južne in vzhodne Azije. Danes je razširjena po vsem svetu, najdemo jo na rahlo zasenčenih in vlažnih mestih, od gozdnih površin do vrtov in dvorišč. Je pogost plevel in v naših krajih velja za tujerodno invazivno vrsto. V magistrskem delu smo raziskovali rast indijskega jagodnjaka pod vplivom različne količine dostopne svetlobe in hranil v tleh in ovrednotili vpliv znotraj vrstne in medvrstne kompeticije. Rastline, rastoče na soncu, so imele večjo biomaso, večje število listov in število ramet kot senčne rastline. Te lastnosti indijskega jagodnjaka smo interpretirali kot fitnes rastline. Največji prirast listov, stolonov in ramet ter največjo svežo in suho maso indijskega jagodnjaka smo zabeležili na soncu z večjo količino hranil v tleh. Opazili smo značilen odziv indijskega jagodnjaka na zmanjšano razpoložljivost svetlobe, in sicer so rastline v senci razvile daljše listne peclje. Indijski jagodnjak v kompeticiji z ekološko podobno avtohtono bršljanasto grenkuljico (Glechoma hederacea L.) ni kazal kompeticijske prednosti. Bršljanasta grenkuljica je uspešnejša v alokaciji dostopnih virov v nadzemni in podzemni del rastline. Rezultati so pokazali, da se indijski jagodnjak kot tujerodna invazivna vrsta lahko prilagaja spremenjenim okoljskim razmeram z razvojem specifičnih lastnosti, ki omogočajo preživetje, rast in razvoj rastline.

Secondary title: Influence of light, nutrients and competition on the growth on indian strawberry (Duchesnea indica (Andrews) Teschem.)
Secondary abstract: Indian strawberry (Duchesnea indica (Andrews) Teschem.) is a perennial herbaceous plant from the Rosaceae family, which originates from the tropical forest areas of South and East Asia. Today it is found all over the world, it is widespread in slightly shaded and moist places, from forest areas to gardens and yards. It is a common weed and in our areas it is considered an invasive species. We investigated the growth of the Indian strawberry plant under the influence of different amounts of available light and nutrients and in the presence of intraspecific and interspecific competition. The plants had the greatest growth of leaves, stolons and ramets, and the greatest fresh and dry biomass in the sun with a higher amount of nutrients. As a common response to reduced light availability, Indian strawberry in the shade invested the most energy in the length of the petiole. The competitive native species Glechoma hederacea L. showed a competition advantage in the allocation of available resources to the roots and shoots. The results showed that the Indian strawberry, as a non-native invasive species, can adapt to changed environmental conditions by developing specific traits that enable the survival, growth and development of the plant.
