Abstract
Aspilia montevidensis is a rustic ornamental species, native to high altitude grasslands of southern Brazil, which takes advantage of direct sunlight and poor soil.
It is highly recommended for use in low cost landscaping, but it is still little used due to low availability of seedlings on the market.
Its propagation by cuttings can facilitate this demand.
The use of growth regulators can benefit the rooting efficiency of this herb.
Thus, the objective of this study was to characterize the number of leaves of the cuttings and concentrations of indolebutyric acid (IBA) most suitable for propagation.
The experiments were conducted in the protected Horticulture sector at the University of Passo Fundo (UPF), Brazil.
The experiments were conducted in the fall and spring of 2010. Treatments consisted of concentrations of IBA (250, 500, 750 and 1000 mg L-1 and the control without application of IBA) and the presence of two and four leaves.
A randomized block design with four replications was used, with twelve cuttings per plot.
It can be concluded that the process of vegetative propagation by cuttings in spring without the use of IBA is best (>75%) for this species, leaving four leaves on the cuttings.
