Resumo
The adoption of biological resources in agriculture
may allow less dependence and better use of finite resources.
This study aimed at evaluating the effects of inoculation with
arbuscular mycorrhizal fungi native to the Brazilian Savannah
associated with the application of mycorrhizal stimulant
(7-hydroxy, 4’-methoxy-isoflavone), in the early growth of
common bean and soybean. The experiment was carried out
in a greenhouse, in a completely randomized design, with
a 7 x 2 factorial arrangement, consisting of five arbuscular
mycorrhizal fungi species, joint inoculation (junction of
all species in equal proportions) and native fungi (without
inoculation), in the presence and absence of stimulant. The
following traits were evaluated: shoot dry matter, root dry
matter, mycorrhizal colonization, nodules dry matter and
accumulation of calcium, zinc and phosphorus in the shoot dry
matter. The increase provided by the arbuscular mycorrhizal
fungi and the use of stimulant reached over 200 % in bean
and over 80 % in soybean plants. The fungi Acaulospora
scrobiculata, Dentiscutata heterogama, Gigaspora margarita
and Rhizophagus clarus, for bean, and Claroideoglomus
etunicatum, Dentiscutata heterogama, Rhizophagus clarus
and the joint inoculation, for soybean, increased the dry matter
and nutrients accumulation.
