The invention relates to the use of oligo-apiogalacturonan compounds, particularly extracted from aquatic plants of the Lemna or Zostera genus, as an agent for stimulating the defence and resistance reactions in a plant, in particular an ornamental plant or a plant of agricultural interest, against biotic and/or abiotic stresses. The invention further relates to a method for stimulating the natural defence reactions of a plant or a portion of a plant against biotic and/or abiotic stresses that includes applying at least one oligo-apiogalacturonan compound in a liquid or solid composition on said plant or a portion of a plant or in the environment of said plant. |
