Abstract

The objective of this work was to select, in a greenhouse, associative bacteria that promote the growth and development of eucalyptus plants. For this, the selection experiment used the AEC 144 clone of Eucalyptus urophylla, the experiment was carried out from March to May 2017, lasting 30 days, the treatments were 17 bacterial isolates and 1 control without inoculation, 4 replications, arranged in DIC. The height, diameter, number of shoots, counting of the number of leaves of the plants, Spad Index and dry weight of aerial part were evaluated. Bacterial isolates JN32R, JN6R, JN5R, JN3R, JM6R, JM21R, JM5R, native to eucalyptus; and strains LGAM82, ZAE94, J11 and N15 promote growth and development in eucalyptus.
