One of the most effective means of increasing urban green areas is the establishment of roof gardens. They have many positive properties and ecological functions, such as filling empty spaces with plants, protecting buildings, dust retention and air cleaning. In the case of extensive constructions, mostly species are used, planted as carpet-like "grass" sods or by installing modular units as plugs; however, with the use of other plant genera, the efficiency of ecological services could be increased by expanding the diversity. taxa have good drought resistance, and these plants tolerate temperature alterations well. Their application would increase the biodiversity, quality and decorative value of roof gardens. Experiments were carried out on nursery benches imitating a roof garden, with the use of modular elements intended for species, which facilitate the establishment of green roofs. In our trial, varieties of two European native species, Vill. 'Uchte' and . L. 'Walberla', were investigated. In order to find and determine the differences between the cultivars and the effects of the media (leaf mold and rhyolite tuff), we drew inferences after morphological (height, circumference, root weight, fresh and dry weight) and physiological tests (peroxidase and proline enzyme activity). We concluded that 'Uchte' is recommended for roof garden conditions, planted in modular elements. Although the specimens were smaller in the medium containing fewer organic components than in the version with larger amounts, they were less exposed to the effects of drought stress. This can be a key factor for survival in extreme roof gardens or even urban conditions for all plants.
增加城市绿地面积最有效的方法之一是建造屋顶花园。它们具有许多积极特性和生态功能，比如用植物填充空地、保护建筑物、滞留灰尘和净化空气。在粗放式建设的情况下，大多使用一些物种，以地毯状“草皮”形式种植或通过安装模块化单元作为插穗；然而，通过使用其他植物属，扩大多样性可以提高生态服务效率。某些分类群具有良好的抗旱性，这些植物能很好地耐受温度变化。它们的应用将增加屋顶花园的生物多样性、质量和装饰价值。利用旨在用于某些物种的模块化元件，在模仿屋顶花园的育苗台上进行了实验，这些元件便于建造绿色屋顶。在我们的试验中，研究了两种欧洲本土物种的变种，即Vill.的‘Uchte’和L.的‘Walberla’。为了找出并确定这些栽培品种之间的差异以及基质（腐叶土和流纹凝灰岩）的影响，我们在进行形态学（高度、周长、根重、鲜重和干重）和生理学测试（过氧化物酶和脯氨酸酶活性）后得出了推论。我们得出结论，‘Uchte’推荐用于屋顶花园条件，种植在模块化元件中。尽管在有机成分较少的基质中植株比在有机成分较多的基质中更小，但它们受干旱胁迫的影响较小。这可能是所有植物在极端屋顶花园甚至城市环境中生存的关键因素。
