Abstract The oligogalacturonides derived from trifluoroacetic acid hydrolysis and their monomer galacturonic acid were tested for their effect on development of strawberry explants (Fragaria x ananassa) in vitro. The addition of oligogalacturonides or galacturonic acid in the plant tissue culture medium at concentrations of 0.1 or 1.0 mM increased shoot and leaf number in the presence of added benzyl adenine. The response to oligogalacturonides or galacturonic acid was maintained in the absence of benzyl adenine but was lessened. Conversely, root elongation was increased in the absence of benzyl adenine. A combined analysis of these experiments also indicated the increase in shoot or leaf number. High-performance anion exchange chromatography of the bioassayed oligogalacturonide samples using a pulsed amperometric detector revealed that the sample consisted of galactouronides with a degree of polymerization from 1 to 5 and the proportion of the monomer was very high (94%).
