摘要：
This work aimed to study the in vitro regeneration of the weed Euphorbia heterophylla from hypocotyls, cotyledon and root explants grown under different concentrations of the hormone 2iP, combined or not with auxin added to MS/2 medium. The parameters analyzed were the number of explants with shoot, number of shoot for explants, number of rooted and acclimatized plants. The results showed an average of two shoot for hypocotyls explants, in 50% of these, front direct organogenesis with the use of 0.5 mg.L-1 of 2iP. No regeneration from the cotyledon and root explants was verified. The root culture developed in all treatments with or without auxin. These results will be able to assist in future physiological tests of resistance of this plant of herbicides.
