Abstracts |
The arbuscular mycorrhizal are known and explored long ago due to the ecological significance and the effects in the growth and nutrition of the plants. Eucalyptus cloeziana, particularly in the studied sites, exhibit different behaviour when compared with other eucalyptus species, establishing in sites of the poor soils and sandy texture, with reduced growth, difficulty to formation of the seedling and nutritional problems. Aiming to evaluate the percentage of mycorrhizal colonization, as well as the density of arbuscular mycorrhizal fungi spores in E. cloeziana plantations, rhizospheric soil and roots samples were collected in twenty sites, distributed in six municipalities of Bahia state, Brazil. The mean results of percentage root colonization ranged from 10 to 96.66% and spore number ranged from 3 to 110 spores/50 cm3 soil, demonstrating high susceptibility of the E. cloeziana to mycorrhization. |
