Plants of Vernonia herbacea (Vell.) Rusby (Asteraceae) were grown under cerrado covered soil or washed solution, solution without nitrogen, solution without phosphorus, and distilled water. In cerrado soil, althougt shoot dry mass and leaf area were higher when complete solution was supplied to plants, fructan contents were significantly lower in the underground organs, suggesting the translocation of these sugars to the growing tissues in the plant tops. The lack of nitrogen did not promote growth of rhizophores in sand or growth of plants in either substrate and the plants accumulated small amounts of fructans, specially fructo-polysaccharides. It is suggested that nitrogen is important to the growth of this plant. Vegetative growth and fructan accumulation were not specially affected by the absence of phosphorus. Neither nutrient treatments nor substrate influenced the distribution pattern of the components of the homologous series of fructans. The data here obtained indicate that nutrient condition is one of the factors defining growth and accumulation patterns in this species. Plants of V. herbacea naturally growing in the cerrado seem to have developed adaptive strategies that supply them with efficient mechanisms of carbon partitioning that favors fructan accumulation in the rhizophores. |
