Invasive plant species are responsible for changing colonized ecosystems by occupying new areas and creating a threat to the functioning of the native flora and fauna populations. Alien plants can produce allelochemicals, substances completely new to indigenous communities. This study investigated the germination seed reactions of L. and L. var. Pers. cv. Rowa on the extracts from the roots, stalks, leaves, and flowers of . Aqueous extracts at concentrations of 1%, 2.5%, and 5% were used in order to determine the allelopathic potential of this alien rose for Europe. With the increase in the concentration of extracts, a decrease in the germination capacity of seeds of the tested species was observed. extracts inhibited the growth of seedlings. Depending on the concentration and type of the extract, changes in biomass and water content in Red Fescue and Red Radish seedlings were also shown. The highest differences in the electrolyte leakages were noted in seedlings treated with 5% rose extracts. The study showed that the aqueous extracts of leaves and flowers had the greatest allelopathic potential.
入侵植物物种通过占据新区域并对本地动植物种群的功能构成威胁，从而改变被殖民的生态系统。外来植物会产生化感物质，这些物质对于本土群落来说是全新的。本研究调查了罗莎（L.）和罗莎变种（L. var. Pers. cv. Rowa）种子对[植物名称未明确]的根、茎、叶和花提取物的发芽反应。使用了浓度为1%、2.5%和5%的水提取物，以确定这种外来玫瑰对欧洲的化感潜力。随着提取物浓度的增加，观察到受试物种种子的发芽能力下降。[植物名称未明确]提取物抑制了幼苗的生长。根据提取物的浓度和类型，还显示了红羊茅和红萝卜幼苗的生物量和含水量的变化。在用5%玫瑰提取物处理的幼苗中，电解质渗漏的差异最大。研究表明，[植物名称未明确]叶和花的水提取物具有最大的化感潜力。
