Abstract
This study aimed the floristic survey and to examine the plant origin and mycorrhization of ruderal plants in the urban areas of Três Lagoas-MS, Brazil, specifically in the housing complex Vila Piloto and the surrounding areas. Our intent was to expand knowledge about native and introduced vegetation in environments with anthropogenic changes. The survey occurred over 12 months and 266 species, distributed into 53 botanical families were identified. This flora was composed of native and exotic plants, especially from Americas (82.7%) and Old World and Australia (17.3%). There were 220 species native to the America’s, but the highest number (60%) was from Brazil. A small percentage of these Brazilian plant species (28.6%) have originated from Cerrado, suggesting that ruderal vegetation was the high represented by native species. Of the 49 species chosen for root mycorrhization verification, 42 showed colonization in varying degrees. Soil fertility was higher than in the typical Cerrado, and the average number of AMF spores (152 per 100 g of dry soil-1) did not indicated soil degradation.
