The influence of some culture systems on the ornamental value of Sedum spurium ‘Fuldaglut’ and Sempervivum tectorum species

Abstract

The purpose of the paper is to analyze the behavior of some ornamental flowering plants cultivated on roofs, on three types of substrate. The used biological material was comprised of mature Sedum spurium ‘Fuldaglut’ and Sempervivum tectorum samples, purchased from specialized nurseries and cultivated in 80/480 cm containers. The experimental scheme includes three variants, with three repetitions each in which various types of culture substrates were used: V1- forest soil; V2 -mixture of peat Novobalt (43%), coconut fiber (30%), composted bark (23%), alginate (4%); V3-blonde peat (40%), brown peat (30%), sand 10% and forest soil (20%). It was found that the substrate type has influenced the growth and development of the Sedum spurium ‘Fuldaglut’ and Sempervivum tectorum plants. Comparing the types of substrate we concluded that the substrate a3, a mixture of blonde peat (40%), brown peat (30%), sand (10%) and forest soil (20%), had the most positive influence, while the substrate a2, a mixture of Novobalt peat (43%), coconut fiber (30%), composted bark (23%), alginate (4%), had the least influence.
