Abstract
Nodal segments of Prosopis chilensis and P. tamarugo from nine month-old plants were investigated as regards their rooting capacity and asexual propagation in vitro. High levels of naphthaleneacetic acid (5-10 mg/l) were most efficient for rooting and regeneration of plantlets in both species, although the inclusion of kinetin and/or gibberellic acid (0.01 mg/l) favoured axillary bud development after root formation. Rhizogenesis was observed after 3-4 weeks, consisting of one or more roots per node independent of preliminary callus formation. Rooting responses and plantlet regeneration were always better in P. chilensis than in P. tamarugo, under the same hormonal treatment.
