Successful stem cutting propagation of Patrinia rupestris for horticulture

Abstract This study was conducted to develop a protocol for the vegetative propagation of Patrinia rupestris (Pall.) Juss., to facilitate its use for ornamental and medical purposes. Cuttings of P. rupestris were treated with distilled water (control), commercial rooting powder (Rooton, 0.4% 1-naphthylacetamide), α-naphthalene acetic acid (NAA), and indole-3-butyric acid (IBA). The stem cuttings pretreated with 2685, 5370 µM NAA or 4920 µM IBA displayed the best rooting traits; the rooting percentage, number of adventitious roots, length of roots, and fresh weight of roots. It would be advisable to use the lower concentration, for economy in using the hormone. We recommend treating cuttings with 2685 µM NAA for the propagation of P. rupestris to produce large amounts of planting materials.
