Legume and herb based special seed mixtures for greening the tram tracks

Original language description

During more than 30 years of collecting activities about 5 500 accessions of legumes, herbs and grasses have been collected in the territory of the Czech Republic. These seed samples represent a vast part of domestic plant diversity. Most of collected samples have been evaluated, regenerated and stored in the national gene bank. 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 of legumes, herbs and grasses suitable for greening of cities, transport constructions, tram and train tracks, revitalisation of damaged areas and apply them practically in special seed mixtures for urban 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 tram tracks under traffic. Five experimental localities in Prague were selected for the evaluation. Urban conditions are characterized by multiple stressors influencing the vegetation, like severe 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 legumes and dicots. Legumes and dicots are very valuable due to their aesthetic value and as feed sources for insects and pollinators. Three most promising seed mixtures are now proposed for legal protection in the form of utility models, and their use will be directed for the climatic conditions of Central European cities.
