Gomphrena macrocephala St.-Hil. (Amaranthaceae) is a perennial herb from the cerrado with medicinal properties and ornamental interest. Plants can be micropropagated through nodal segments, but acclimatization is difficult. The aim of this study was to establish a relationship between anatomical aspects of the roots and the acclimatization process. When cultures were supplemented with IBA, callus and thick and frangible roots appeared at the base of the microcuttings. A fragile vascular connection between roots and shoots was observed. Abnormal adventitious roots showing alteration in the vascular cylinder and hypertrophy of the cortical cells were also noted. These roots interfere in the transfer to extra vitrum conditions. When no growth regulator was...
