Abstract Galactoglucomannan-derived oligosaccharides (GGMOs) (degree of polymerization 4–8) isolated from the wood of poplar (Populus monilifera Ait.) were shown to be inhibitors of the 2,4-dichlorophenoxyacetic acid-stimulated elongation growth of pea (Pisum sativum L. cv. Tyrkys) and spruce [Picea abies (L.) Karst] stem segments. A dependence on the concentration of GGMOs (between 10-5-10-10M) as well as plant species was ascertained. Pea stem segments were much more sensitive (10-10M) than spruce (10-8M). The GGMOs did not exhibit toxicity even at high concentrations and during long-term bioassays. The timing of the action of GGMOs and auxin in the growth process was also studied.
