Vegetative Propagation of Southwestern Plants: Ambrosia deltoidea, Buddleja marrubifolia, Vauquelinia californica, and Vauquelinia corymboss

The vegetative propagation of ambrosia deltoidea, buddleja marrubifolia, vauquelinia californica, and vauquelinia corymbosa species was discussed. Highest root percentage was achieved with a treatment of Hormodin 1, and the lowest rooting occurred on plants treated with Dip 'N Grow. It was found that while there was no significant difference in rooting among hormone treatments, plants treated with 3000 ppm Hormodin had the lowest percentage of unrooted cuttings. The significance of shade treatment that increased the percentage of commercially viable cuttings from 38% without shade to 61% with shade was also elaborated.
