The yellow-jasmine (Jasminum mesnyi Hance – Oleaceae) is a ornamental shrub used in landscape gardening. This paper aims to analyze the influence of naphthalene acetic acid (NAA) with concentrations varying from 0 to 5,000 mg kg-1, as well as, the vermiculite and Plantmax HA® substrates in the rooting of stem cuttings of J. mesnyi. In october 2003, herbaceous cuttings were collected from the branches of ten matrices, germinated one year before. The herbaceous cuttings were set up in a shape of 5.0 cm long by 0.24 cm of diameter, containing two leaves on the apex. The experiment was conducted in a randomly delineation with 4 treatments, 4 repetitions with 10 cuttings for each plot, being maintained inside a greenhouse climatically controled (24 ± 2 oC e 90% HR). After 40 days the analyses were made for the rooting percentage, the number of roots per cuttings, length of the five longer roots formed per cuttings, percentage of unrooted living cuttings, percentage of dead cuttings, percentage of the initial leaves per cutting, and percentage of cutting with sprout. The best rooting result was accomplished by the vermiculite substrate (100 and 97,5%) with no influence of NAA. For the rooting of yellow-jasmine’s is not necessary the use of NAA.
