The effects of the growth regulators a-naphthalenacetic acid (NAA), 3-indolebutyric acid (IBA) and maleic hydrazide (MH) on the lignification of 2-month-old chestnut sprouts (F4 of Castanea sativa Mill, x 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.
