This project aims to contribute to the optimization of micropropagation protocol of the oleaginous species argan (Argania spinosa (L.) Skeels) and olive (Olea europaea L.) in order to propagate varieties that can withstand the future rising temperatures and rising shortages due to climate change, which will have a major impact on the Iberian peninsula in the coming years. We have used different treatments with auxin, both in vitro and in vivo, cuttings of these oleaginous species to study the formation of callus and adventitious roots in 22 cuttings of argan in vitro, 115 cuttings of argan in vivo and 1248 cuttings of olive in vivo. With the morphological parameters collected during this work (callus formation, adventitious root number, leaf number and length of cuttings), we have carried out several statistical studies based on analysis of variance to identify which treatments and what parameters have a major influence in callus formation and development of adventitious roots in these cuttings.Our results indicate that there are statistically significant associations in callus formation between treatments with auxin and without auxin in the cuttings of argan in vitro. Our treatments with auxins for argan and olive cuttings in vivo have allowed us to obtain adventitious roots in cuttings of both species with high efficiency, and we have observed statistically significant differences in obtaining callus and adventitious roots and the different treatments with auxin. In addition, we have found positive correlations between the number of roots and callus formation in cuttings of argan in vivo and between callus formation and leaf number in cuttings of olive in vivo. Our procedures will increase the effectiveness of vegetative propagation of olive and argan.
