<b>Induction of apical bud sprouting in seedlings and rooting of cuttings of mangosteen</b> - DOI: 10.4025/actasciagron.v29i5.815

Abstract

With the objective to induce apical bud sprouting in young mangosteen seedlings an experiment was carried out with the application of the plant growth regulators kinetin (0, 100 and 400 mg L^-1) and gibberellin GA4+7 (50 mg L^-1). To obtain rooted cuttings two other experiments were performed: a) application of indolbutyric acid at the concentrations of 0, 100, 500 and 1000 mg L^-1 and b) application of α naphtaleneacetic acid, at 6000 mg L^-1. In these trials cutting from orthotropic branches were utilized. The results indicated the possibility of using plant growth regulators to obtain more uniform root stocks in a shorter nursery stage and, despite the low percentage of rooting the planting material obtained from cuttings has a great practical potential, since the size of the rooting cuttings is equivalent to that of one year old seedlings.
