Abstract

The isolation and characterization of wild strains
of Azospirillum was done in the rhizosphere of the commercial
sugarcane varieties Ja60-5 and C266-70 on the Red and
Yellowish Ferralitic soils from Havana and Ciego de Avila
provinces. The nitrogenase activity of isolated bacteria was
assayed by acetylene reduction technique (ARA) and its
growth promoting activity in sugarcane plantlets. Strain
characterization was achieved using morphological and
biochemical tests. Significant concentrations of bacteria of
104 cels.g-1 of roots were obtained, mainly on Ja60-5 variety in
both soils. Four strains similar to Azospirillum were isolated
and 8 INICA strain was selected due to its high ARA and
sugarcane plant growth values.
