MYCORRHIZAL DEPENDENCY OF THE LEGUME Mimosa artemisiana HERINGER & PAULA

Abstract

ABSTRACT: This study aimed to evaluate the degree for mycorrhizal dependency of Mimosa artemisiana. The seeds were innoculated with rhizobium and arbuscular mycorrhizal fungi Glomus etunicatum Becker & Gerdemann in level the P disponible (1, 5, 32, 84 e 240 mg/kg) extract Mehlich I. Mycorrhized plants presented a typical curve, reducing growling in the greater P dose in relatives to the non-innoculated, which presented a linear response to P. The major responses to Glomus etunicatum innoculation were observed with P available between 32 and 84 mg/kg. The plants clased to responde innoculation when P available mycorrhizal dependency this Mimosa artemisiana is intermediate because it ceases responding to AMFs in high levels of P available.   KEY-WORDS: inoculation, Glomus etunicatum, phosphorus.
