This research was an attempt to evaluate the herbaceous cutting rooting of two vine rootstocks (‘Campinas’ - IAC 766 and ‘Jales’ - IAC 572) on three types of plant growth medium (hull rice coal, vermiculite - small granules and vermiculite - medium granules). Cuttings were taken from a virus-free stock plant, through the removal of green branches. Firstly, preparation of cuttings consisted on the elimination of the leaves of the basal portion, leaving one leaf in the superior part of each one. After that, the cuttings were placed in plastic boxes containing different types of growth medium on mist chamber. A randomized design was used as statistical model with 6 treatments and 5 replications. Each plot was composed of 10 cuttings. Once the proper rooting was observed, the effect of roostock and growth medium was evaluated. It was possible to conclude that: a) the average porcentage of rooted rootstocks on the different growth medium is high (90%); b) hull rice coal provides the best results for cutting rooting for both rootstocks; and c) ‘Campinas’ rootstock is superior than ‘Jales’ regarding the number of roots per cutting and the root system weight.
