Abstract
The mahogany tree, Sweitenia, which grows as natural populations in tropical America and parts of Asia and Africa, is a highly valued timber tree known for its redwood color, strength, durability, water resistance and aesthetic appeal. Callus tissues were established from aseptic segments of cotyledons and leaves of mahogany (Sweitenia mahogany Jacquin and S. macrophylla King). They were maintained on a modified Murashige & Skoog (MS) medium supplemented with 2 mg/1 of 2,4-dichlorophenoxyacetic acid (2,4-D) and 1 mg/1 of -naphthalene acetic acid (NAA). The explants proliferated extensively on agar medium in the growth chamber at 25 ± 1°C in 2–3 weeks. The callus from cotyledonary tissues were very soft and white in color and further subcultures resulted in a loose “snow-flake” appearance. Callus obtained from leaves were almost transparent and colorless. Experiments on in vitro culture and micropropagation of mahogany suggest that mass propagation of this tree is possible using this method, particularly because of decline in natural populations.
