The adventitious rooting process of in vitro cultured plantlets is a technique that has been employed for the vegetative propagation of a significant number of native and exotic species. Many factors are associated with the rooting stage influencing positive and/or negatively the establishment of micropropagation protocols. The objective of this work was a literature review of the main inherent factors concerning in vitro rooting process including the correlation among others the endogenous and exogenous auxins levels, juvenility, genotype, mineral nutrition, culture medium conditions, addition of growth regulators and other substances as phenolic compounds and active coal besides growth environmental conditions of in vitro cultures. Although the complete elucidation of all processes involved with rooting of in vitro cultured plants has not been achieved so far, a comprehensive study of the main factors that interfere on rooting is fundamental for the establishment of new researches that might contribute for the rooting of economically important plants.
