ABSTRACT

Sapindaceae family presents notable richness of liana species in the Neotropics. Many of them
are potentially ornamental, but still unexplored. Two Sapindaceae species were selected to test
the efficiency of thiamine hydrochloride in plant propagation from stem cuttings. Thiamine
hydrochloride has an unexplored potential for higher and better rooting of plant cuttings and it
is a cheaper alternative to the traditional usage of phytohormones. Results showed no difference
between treatment and control for all root variables evaluated in the two species studied.
Seedling production from cuttings does not require application of thiamine hydrochloride in
the concentration used to ensure rooting; only water irrigation is sufficient. However, further
experiments involving different concentrations of thiamin hydrochloride should be conducted
to detect whether different concentrations influence rooting.

Keywords: vitamin B1, vegetative propagation, seedling production.
