20.500.12556/DKUM-79470 Potencialni alelopatski učinki listnih izvlečkov invazivnih tujerodnih rastlin na rast izbranih ruderalnih vrst Potentially allelopathic effects of invasive alien plants leaf extracts on growth of selected ruderal species V magistrskem delu smo raziskovali vpliv vodnih izvlečkov navadne barvilnice (Phytolacca americana L.), japonskega dresnika (Fallopia japonica Houtt.) in peterolistne vinike (Parthenocissus quinquefolia Planch) na kalice sivozelenega muhviča (Setaria pumila L.). Preučevali smo, ali izvlečki iz različno starih listov zavirajo rast sivozelenega muhviča, in ali se koncentracije barvil v listih invazivnih rastlin glede na starost listov (mlajši in starejši) razlikujejo. Po štiritedenskem zalivanju kalic muhviča, ostriženih na enotno višino, z 0,1, 1 in 10 % koncentriranimi vodnimi izvlečki zgoraj naštetih invazivk, smo kalicam izmerili dolžino prirasta in dolžino korenine, prav tako pa smo določili suho in svežo maso vseh kalic po posameznih tretmajih. Ugotovili smo, da so najnižje povprečne vrednosti velikosti kalic in dolžin korenin bile dosežene vedno pri izvlečkih navadne barvilnice ne glede na starost listov; variirala je samo koncentracija izvlečka, pri kateri smo dosegli najnižje povprečne vrednosti. In the master’s thesis we investigated potential effect of American pokeweed (Phytolacca americana L.), Japanese pokeweed (Fallopia japonica Houtt.) and Vigrinia creeper (Parthenocissus quinquefolia Planch) waterous leaf extracts on Yellow foxtail (Setaria pumila L.). We researched whether waterous extracts have negative impact on growth of Yellow foxtail seedlings and if concentrations of leaf pigments differ among young and mature, senescened leaves. After four-week treatment with 0,1, 1 or 10 % leaf extracts from above mentioned invasive species, we measured each seedling shoot height and root length. We also weigthed raw and dry mass for shoots and roots separately. We found out that lowest average measurements were observed during treatments with American pokeweed, regardless of leaves age. The only variable was concentration of the waterous extracts. alelopatija tujerodne invazivne vrste sivozeleni muhvič (Setaria pumila L.) navadna barvilnica (Phytolacca americana L.) japonski dresnik (Fallopia japonica Houtt.) peterolistna vinika (Parthenocissus quinquefolia Planch) allelopathy alien invasive species Yellow foxtail (Setaria pumila L.)
