Resumen:
The empirical evidence obtained by farmers of Huechelepon area (commune of Melipeuco, La Araucania, Chile) indicates that the specie Dasyphyllum diacanthoides, besides presenting medicinal properties, is a winter forage alternative. This property along with its status as endemic forests of Chile requires reconciling the use and conservation of this species. The aim of this study was to propagate D. diacanthoides by semi lignified cuttings and determine the effect of the presence of thorns in the cuttings and North or South exposure mother plants in rooting. The study was performed using endogenous resources, so the evaluated variables were determined on the basis of knowledge of farmers. The experimental design included four treatments: T1: cuttings of plants with southern exposure and thorns, T2: Stakes southern exposure plants without thorns, T3: cuttings of plants with northern exposure spineless and T4: cuttings of plants with northern exposure with thorns. Each treatment consisted of 25 replicates and a complete randomized design for location of the cuttings in the greenhouse was used. Cuttings from plants in North slopes had higher percentages of survival, rooting and callus formation the plant on hillsides South. Mann-Whitney U test showed significant differences between stakes with and without spines north only exposure length roots (p <= 0.05). The vegetative propagation of cuttings D. diacanthoides by semi lignified is feasible. The best results are obtained with stakes thornless plants mothers with Northern exposure.
