Secretions of the Meloidogyne incognita females stimulated growth and influenced the nucleic metabolism (on the analogy to DCPA and IAA) of isolated cells and tissues of susceptible plants (carrot, tomato) only in combination with extracts of these plants leaves. Invasion larvae formed galls on isolated roots of alfalfa and tomato only with additional dressing of the roots either by extracts of leaves of these plant sprouts or by complex growth-stimulating substances. The investigations are significant for understanding plants anomalous growth mechanisms with nematodoses.
