What is the Effect of Thiamine Hydrochloride on Rooting of Sapindaceae Stem Cuttings?

摘要

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.
