Abstract
During growing and flowering seasons for five years, comparisons were made between upper and lower leaf surfaces microflora of ragweed plants grown in three areas: a relatively non-contaminated site, a communal landfill, and a complex contaminated with heavy metals. Results indicated that phyllospheric microbial communities were qualitatively and quantitatively related to metal content in plant leaf, leaf surfaces and metal contaminated ecosystems where the plants grown. Results showed that there was a high positive correlation between phyllospheric microbial population densities and Cd, Ni, and Zn content in ragweed leaves, while it was low in presence of Cu. Comparatively, the correlation was at its highest in the case of aerobic heterotrophic bacterial population densities and more than yeasts and filamentous fungi communities. The most common diversities of metal resistant microorganisms were related to Pantoea agglomerans, Pseudomonas savastanoi, P. putida, Bacillus cereus, Corynebacterium striatum, Cryptococcus and Alternaria.
