摘要

The necessity for increase in sugarcane production encouraged the development of some studies with the objective of optimizing production. Thus, the objective of this study was to evaluate the potential of the endophytic bacteria Herbaspirillum spp. and the Bacillus spp. in sugarcane growth promotion. The research was performed at the Agricultural Microbiology Laboratory of the Federal University of Alagoas. The isolates were obtained from sugarcane and subjected to qualitative production of Indole Acetic Acid (IAA), gibberellins, cytokinins, antagonism, phosphate solubilization and rout and budding of sugarcane gems. Four isolates (ISO1, ISO3, ISO4 and ISO5) were able to produce auxins in vitro. To detect the presence of gibberellins and cytokinins, isolate 4 (ISO4) showed the greatest proportional weight of cotyledons differing significantly than the other treatments and the control. However, there was less weight hypocotyl to the same strain. The isolates showed varying rates of solubilization, with a mean of 1.70 obtained by isolate 1, showing the higher solubilization. All isolates exerted an antagonistic effect against the pathogen. The increases in budding, as well as rooting and seedling growth varied according to the isolated and no deleterious effect was observed in any of them. The positive interaction between endophytic bacteria and sugarcane was noted.
