SUMMARY The effects of the growth regulators α‐naphthalenacetic acid (NAA), 3‐indolebutyric acid (IBA) and maleic hydrazide (MH) on the lignification of 2‐month‐old chestnut sprouts (F 4 of Castanea sativa Mill. × Castanea crenata Siebb. et Zucc.), both with and without aetiolation, were studied. The results obtained show that aetiolation on its own has no effect on lignification. Treatments with IBA+NAA or with MH significantly promoted lignification. When, however, auxines were administered in combination with aetiolation, the promotion effect was significantly stronger.
