Activité antifongique des huiles essentielles de Ocimum basilicum L. (Lamiaceae) et Cymbopogon schoenanthus (L.) Spreng. (Poaceae) sur des micromycètes influençant la germination du Maïs et du Niébé

Abstract

Tests of germination of the corn seeds (Zea mays L.) and cowpea seeds (Vigna unguiculata (L.) Walp.) are made in the presence of phytopathogenics and toxinogenics fungus isolated from pastoral grounds in the south Togo. The results obtained show that these micromycètes can induce in vitro a reduction of germination rate of these two seeds. Essential oils of Ocimum basilicum and Cymbopogon schoenanthus are clearly indicated to fight against the fall of the germinative capacity of these seeds. Among fungus tested, Nigrospora oryzae seems the least sensitive strain at the strongest concentration (1,14 μl/ml) used. © 2006, Taylor & Francis Group, LLC.
