Tolerance of Anadenanthera peregrina to Eucalyptus camaldulensis and Eucalyptus grandis essential oil as condition for mixed plantation

摘要: With the purpose of selecting species woody Caatinga for mixed plantations with Eucalyptus spp., allelophatic effects E. camaldulensis and grandis essential oil were studied on growth activities Anadenanthera peregrina. The plants closed in glass chambers presence volatile or at concentration 13 nl.cm-3. number leaves, height diameter soil lever compared before, immediately after 30 days. Chlorophyll a b, carotenoids dry mass evaluated treatment application. There was no inhibitory effect oils A. camaldulensis, which more adapted to semi-arid conditions, planted mixture stands two native legume species, inoculated Rhizobium arbuscular mycorrhizal fungi. did not inhibit years cultivation.
