Investigation the capability of native herbaceous species of Gorgan as the ground covers

Lawns and ground covers are considered as main source of beautifulness and filtering air atmosphere form dust and toxins, protecting environment from dryness and warmness. Moreover they are major elements in freshness of the atmosphere and reducing environmental pollution. With above idea, current researches have been taken place to investigate cultivation of some endemic lawns and ground covers as replacement for exotic introducing varieties. From a 20 early introduced endemic species, 10 were selected for pot growing alongside with a well known species from Netherland. A factorial static based on a completely randomized design were used for statistical analysis. Major comparing indexes including growth length, greenery during two hot and cold picks, and plant density. Experiment was conducted in 25cm diameter pot, each containing 10 plants and there were four replications for each species. Results showed that four endemic species are comparable with exotic importing species including Ophiopogon sp, Dichondra sp, Cynodon dactylon and Potentilla reptans.
