Table 1. Carbohydrates identified on sugarcane methanolic leaves extracts by GC-MS TOF.

The treatments were inoculation with G. diazotrophicus and H. seropedicae (PGPB), bacteria and humic acid (PGPB+HA) or only humic acid (HA) isolated from vermicompost. The data were expressed in respect to the control treatment (%).
