Abstract

Pectic oligosaccharides or oligogalacturonides
derived from plant cell walls provoke biological effects on plant
growth and development. In the current work a pectic
oligosaccharide mixture (DP 7-16 of galacturonic acid residues)
was evaluated concerning its effect on the formation and
enlargement of roots in African violet (Saintpaulia ionantha)
leafstalks compared to an auxin (indol acetic acid) and the
galacturonic acid monomer. It was found that the treatment
with oligogalacturonide mixture at concentration of 10 mg.L-1 advanced the appearance of roots in the base of violet leafstalks
12 days after applying the treatments, regarding the control,
and even the indoleacetic acid; although at 25 days no
statistical differences were found among treatments. Root
enlargement was not affected by pectic oligosaccharides, only
galacturonic acid derivative increased root size related to con-
trol values. It was concluded that pectic oligosaccharides had
a rooting behavior and reduced time for root rising in the base
of violet leafstalks.
