This study analyzed the relationship between environmental factors, especially air pollution and climatic conditions, and non-structural carbohydrates (NSC)n plantsf Lolium multiflorum exposeduring 10 consecutive periodsf 28ays at a polluted site (Congonhas) and at a reference siten Sao Paulo city (Brazil). After exposure, NSC composition and leaf concentrationsf Al, Fe, Cu, Zn, Pb and Cd were measured. The seasonal patternf NSC accumulation was quite similarn both sites, but plants at Congonhas showed higher concentrationsf these compounds, especially fructansf low and mediumegreef polymerization. Regression analysis showed that NSCn plants growing at the polluted site were explained by variationsn temperature and leaf concentrationf Fe (positive effect), as well as relative humidity and particulate material (negative effect). NSCn the standardized grass culture,n addition to heavy metal accumulation, mayndicate stressing conditionsn a sub-tropical polluted environment.
