Special seed mixtures for greening the tram tracks and their performance

Original language description

During more than 30 years of collecting activities more than 5 000 accessions of genetic resources have been collected in the territory of the Czech Republic. These seed samples represent a vast part of domestic plant diversity. Most of the collected samples have been evaluated, regenerated and stored in the national gene bank. The most promising accessions are further evaluated in subsequent projects. The main aim of the project No. SS01020023: “Germplasm for cities and landscape”, financed by Technology Agency of the Czech Republic (TACR) is to select and evaluate domestic genetic resources (promising cultivars and accessions collected in the wild) of grasses, legumes and dicotyledonous plants suitable for greening of cities, transport constructions, tram and train tracks, revitalisation of damaged areas and practically apply them in seed mixtures for special conditions. Selected genotypes are tested on physiological limiting factors and survival under extreme conditions in growing chambers. Nine special seed mixtures using resilient genotypes were compiled and since 2021 have been evaluated in trials performed on real tram tracks under traffic. Five experimental localities were selected for the evaluation. Urban conditions are characterized by multiple stressors influencing the vegetation, like great drought, high temperatures, salinisation, intensive direct insolation or deep shading on the other hand. Based on the results it can be concluded, that only limited number of plants species and their genotypes could successfully resist in this inhospitable environment. Grasses cope much better with the extreme conditions of urban climate than dicots and legumes. Three most promising seed mixtures will be proposed for legal protection in the form of utility models, and their use will be directed for the extreme climatic conditions of Central European cities.
