Summary

The nutritional status of four aluminium accumulators (Palicourea rigida, Vochysia elliptica, Qualea parviflora andMoconia albicans) and four nonaccumulators (Ouratea hexasperma, Roupala montana, Caryocar brasiliense andSclerolobium paniculatum) of the cerrado vegetation of central Brazil was compared over a period of one year. There were no significant differences between the two groups of species in the seasonal variations of leaf concentrations of N, P, K, Ca or Mg. The differences among the species within the groups were more marked than that between the groups. The younger leaves of all species showed higher concentrations of P and K, irrespective of their Al levels. The mature leaves of nonaccumulators had significantly higher levels of Al than younger leaves, but among accumulators the difference between young and mature leaves was significant in only one of the species.
