Cuttings from secondary branches of Pinus caribaea var. hondurensis were collected in April from two years old "ortets', in Viçosa, Minas Gerais. Following treatment with indol butiric acid, indol propionic acid and powdered charcoal, the cuttings were planted in a bed of washed sand, and observed in order to determine the effect of these substances on the number of stems rooted. During the first two months a plastic cover was used to reduce drying effects on the cuttings. The results obtained after four months permit the conclusion that there was no difference between treatment substances in terms of the number of cuttings rooted.
