The vegetative propagation of nanche (Malpighia mexicana A. Juss. and Byrsonima crassifolia (L) H.B.K.) was evaluated, under shade at 70 and 90%, and Indole butyric acid (IBA) at 1 000, 3 000 and 10 000 ppm and a control. The stem cuttings were collected in Oaxaca, Mexico, and the experiment was established at the Colegio de Postgraduados, Montecillo Campus. 240 stem cuttings of 20 cm of each species were impregnated 5 cm from the base with IBA treatment and seeded at 10 cm depth in 5 L trays filled with peat with sand (1:1 v/v); these combinations resulted in 16 treatments, each with 3 replicates of 10 stem cuttings (experimental units) that were established in a BCA design. At 7 months the percentage of survival, sprouting, cuttings with callus and rooting, and number and length of roots were evaluated. The ANOVA and the Duncan test of means (p≤ 0.05), indicated that the two species showed survival and sprouting, but only M. mexicana showed roots; shadow at 70% was better and in these variables, the control overcame the other treatments; however, only the cuttings treated with IBA showed roots. B. crassifolia produced callus in the stakes when 10 000 ppm IBA was used.

Keywords : cloning; rooting promoters; woody stakes.
