Polylepis incana Kunth (queñoa), is a species that has diverse local uses; however, it has a low germination power in natural conditions. The objective of this research was to compare the germination power of Polylepis incana, with coconut, residual and untreated water treatments. An experiment was set up with three types of water and five doses of water (5, 10, 15, 20 and 25 ml). The germination was developed in 15 trays, in each one 750 g of substrate and 20 seeds were added. The irrigation was done daily with different amounts of water, from 5 to 25 ml. The percentage of germination power, temperature and soil pH were recorded daily. The statistical analyses were carried out in the INFOSTAT program. The highest germination power of seeds was registered with irrigation with residual water (9 %), while seeds irrigated with coconut and untreated water reached 4 %. Therefore, a 9 % germination power of P. incana seeds, irrigated with residual water, was obtained.
