Resumo: | Abstract Platanus, an arboreal and deciduous plant, is widely adapted and can be used for several purposes. Despite producing viable seeds, production of platanus seedlings usually occurs through vegetative propagation; cuttings are the best and most efficient source for obtaining seedlings. Although cuttings offer a practical and easy method to obtain seedlings in different vegetable species, they are influenced by several factors, both external and internal. The present study aimed to analyze the behavior of plantain cuttings planted in sand subjected to damage or no damage at the cuttings base, and planted at depths of 20 and 40 cm. Experiment was carried out at the experimental station of horticulture and protected cultivation of UNIOESTE-Brazil, in a randomized 2X2 factorial design, which comprises both, planted at 20 cm and 40 cm depths, with 5 replicates and 5 cuttings per replicate. After 170 days of incubation, injured and non- injured cuttings, were evaluated for rooting percentage and cuttings sprouted, length of roots and medium length of stems, stem diameter, number of leaves per stem, and dry mass of roots and shoots. No significant differences were observed in cutting injury. All variables analyzed presented higher values when cuttings were planted at 20 cm depth. Results indicate that planting of platanus cuttings at 20 cm depth leads to better rooting rates and vegetative development.
