The micropropagation is an important biotechnological tool for obtaining and maintaining mother
grapevine plants with high quality plant health. The objective was to evaluate the establishment and
multiplication in vitro and ex vitro acclimatization of grapevine cultivate Bordô in different culture
media without adding growth regulators. Grapevine nodal segments were cultured in five culture media
formulations without adding growth regulators. It was evaluated the number of leaves and roots,
length of roots and shoots, replication rate, relative chlorophyll index, percentage of regenerated and
rooted plants, dry biomass of shoot, root and total plants grown in vitro and after acclimatization. In
vitro propagation of grapevine Bordô through nodal segments provided high rates of regeneration and
rooting. High survival rates were obtained in the acclimatization of Bordô. Considering all the variables, culture media Roubelakis and Zlenko showed the best growth rates and development for shoots
and roots, and in vitro multiplication rate of Bordô grapevine cultivar.
