In vitro culture of cotyledon tissue of Castanea sativa Mill

Establishment of callus tissue culture from cotyledon fragments of Castanea sativa Mill. is described. The explants were grown on various combinations of auxins (IAA, IBA, NAA, 2,4-D) and cytokinins (K, BA) to induce callus and regeneration of organs. The best growth occurred on basal medium with 2,4-D (1 and 10 mg/l) plus both K or BA (0.5 mg/l). Root regeneration was achieved with both IBA and NAA (10 mg/l) supplemented with K or BA.
