Use of Pectimorf to Spathiphyllum sp. micropropagation
Main Article Content
Abstract
a sustainable methodology to achieve high plant multiplication
rates in Spathiphyllum sp., in which BAP (6-Bencilaminopurine)
was reduced or removed from the culture medium and
substituted by Pectimorf, an oligogalacturonide mixture
obtained at INCA that proved to have biological activity in
vegetal species at concentrations of 5 and 10 mg.L-1. No
significant differences were recorded among treatments,
concerning plant height and leaf number in any evaluation
performed. The treatment consisting of BAP reduced to half
the concentration of the control medium (0.5 mg.L-1) and the
addition of 10 mg.L-1 Pectimorf achieved the highest amount
of plant sprouts. Results validate the use of Pectimorf for in
vitro propagation of this highly-demanded ornamental species
in our country.
