-Ecosystems contamination by residues of pesticides requires special attention to the herbicides subject to leaching. The objective was to select tree species to rhizodegradation contaminated by residues of 2,4-D and atrazine and to recompose riparian areas to agricultural fields, then reducing the risk of contamination of water courses. A total of 36 treatments consisted of the combinations of forest species were evaluated [Inga marginata (Inga), Schizolobium parahyba (guapuruvu), Handroanthus serratifolius (ipê amarelo), Jacaranda puberula (carobinha), Cedrela fissilis (cedro), Calophyllum brasiliensis (landin), Psidium mirsinoides (goiabinha), Tibouchina glandulosa (quaresmeira), Caesalpinia férrea (pau-ferro), Caesalpinia pluviosa (sibipiruna), Terminalia argêntea (capitão) and Schinopsis brasiliensis (braúna)] and three solutions simulating leachate compound (atrazine, 2,4-D and water -control), with four replicates each. The characteristics measured were plant height, stem diameter, number of leaves, leaf area and dry biomass, and foliar nutrition. Forest species survived the herbicide application, and most showed an increase in macronutrients even under an herbicide application, and the Inga had the highest tolerance regarding growth analysis. It is recommended to use species that are more tolerant to Atrazine and 2,4-D in field experiments to confirm previous results of this simulation.Keywords: Inga marginata; Tolerance; Phytoremediation. CRESCIMENTO E ANÁLISE NUTRICIONAL DE ESPÉCIES ARBÓREAS EM SUBSTRATO CONTAMINADO POR HERBICIDAS LIXIVIÁVEISRESUMO -A contaminação de ecossistemas por resíduos de defensivos agrícolas, especial atenção deve ser dada para os herbicidas passíveis de lixiviação. O objetivo foi selecionar espécies arbóreas para a rizodegradação de ambientes contaminados por resíduos de 2,4-D e atrazine, e para recomposição de mata ciliar aos campos agrícolas e, consequentemente, diminuir riscos de contaminação de cursos hídricos. Foram avaliados 36 tratamentos compostos pela combinação de 12 espécies florestais: [inga-Inga marginata Willd, guapuruvu -Schizolobium parahyba (Vell), ipê amarelo-Handroanthus serratifolius (A.H.Gentry) S.Grose, carobinha -Jacaranda puberula Chan, cedro-Cedrela fissilis Vell, landin -Calophyllum brasiliense Camb, goiabinhaPsidium myrsinoides Berg, quaresmeira-Tibouchina granulosa Cogn, pau-ferro -Caesalpinia ferrea Mart, sibipiruna -Caesalpinia pluviosa DC, capitão -Terminalia argentea Mart & Zucc e braúna-Schinopsis brasiliensis Enge S.F.Blacke] e três soluções simulando o composto lixiviado (atrazine, 2,4-D e água -controle), com quatro repetições cada. Foram mensuradas a altura da planta, o diâmetro do caule, o número de folhas, a área foliar e o acúmulo de biomassa seca e a nutrição foliar. A maioria das espécies apresentou increaseo 586Revista Árvore, Viçosa-MG, v.40, n.4, p.585-594, 2016 FIORE, R.A. et al.em macronutrientes mesmo submetidas à aplicação dos herbicidas, sendo que o inga apresentou maior tolerância em relação as análise de crescimen...
