The Fragments of cladodes of two varieties of palm, spineless cactus and elephant ear, were grown in Murashige and Skoog (1962) culture medium, containing growth regulators, then the flasks were open, the seedlings were wash under running water and subjected to acclimatization in a greenhouse with a system of programmed nebulization and constant temperature of 30° C in which four types of substrate were tested: clay sand, commercial organic substrate, clay sand with bovine manure and clay sand with poultry litter. After 120 days of monitoring, the analysis of variance test (ANOVA) showed a statistical difference in relation to the longitudinal nd transversal diameter of the seedlings, the data were collected up to 30, 60, 90 and 120 days, at the end of this period it was observed that the treatment of poultry litter followed by organic substrate stimulated young cladodes providing a greater longitudinal and transversal diameter for a spineless cactus variety and either an elephant ear variety.
