Abstract

Diplomsko delo obravnava lastnosti populacije navadne česnovke (Alliaria petiolata) v okolici Maribora, ocenjene s pomočjo znakov posameznih osebkov populacije. Zanimalo nas je, kakšne so lastnosti populacije navadne česnovke v avtohtonem okolju in iz literature poizvedeti, kakšne so njene lastnosti v okolju, v katerem se pojavlja kot invazivna vrsta. Eno izmed glavnih vprašanj, ki se nam je porajalo, pa je bilo, zakaj je v okolju, kjer ni invazivna, postala močno dominantna in zakaj ta dominanca ne prevlada v avtohtonem okolju. Na terenu smo popisali osnovne parametre populacije, kot so višina rastlin, število stebel, število luskov, število obžrtih in število neobžrtih listov. Po opravljenih meritvah je sledilo še štetje semen, ki smo ga s pomočjo predhodnega natančnega popisa rastlin opravili na domu. S pomočjo vseh pridobljenih podatkov smo se lahko lotili statističnih analiz posameznih parametrov in korelacijskih odnosov med posameznimi spremenljivkami. Na koncu je sledila še primerjava lastnosti populacije s populacijo v okolju, kjer je česnovka invazivna in dominantna vrsta. Ugotovili smo, daso vzroki za uspešnost invazivnosti navadne česnovke v novem okolju lahko zelo različni. Rastlina v novo naseljenem okolju nima naravnih sovražnikov, ki bi rastlino uničevali, ima alelopatski vpliv na druge rastline, je dober kompetitor, značilno je tudi, da proizvede veliko količino semen, ki posledično privede do agresivnega razmnoževanja rastline.

Secondary title: Characteristics of Allaria petiolata population in the vicinity of Maribor
Secondary abstract: This diploma thesis deals with the characteristics of the garlic mustard population (Alliaria petiolata) in Maribor and surroundings, estimated according to characteristicsof an individual garlic mustard. Our aim was to establish the characteristic of the garlic mustard populationin its autochthonous environment and examine the literature to determine its characteristics in the environment where it appears as an invasive species. One of the main issues was why it became so dominant in the environment, where it is not invasive and why such dominance does not prevail also in the autochthonous environment. Basic population parameters such as height, number of stems, number of husks, number of eaten and number of intact leaves were conducted on the field. After the precise inventory we counted the seeds. Having all these data we were able to conduct statistical analysis of individual parameters and correlations between individual variables. Furthermore, we compared the characteristics of our population with the characteristics of the population in the environment where garlic mustard is invasive and dominant species. We concluded that there are many causes for the success of the invasive nature of garlic mustard in a new environment. In a new environment garlic mustard does not have natural enemies, it has allelopathic effect on other plants, is a tough competitor, it produces a large number of seeds which consequently leads to its aggressive reproduction.
