In Gabon Entandrophragma utile is uncommon, in most regions even rare. Prospects The low growth rates under entandropragma conditions, the long time needed to reach maturity in terms of fruit production and poor dispersal ability of the seed seem to be serious drawbacks for sustainable management entanfrophragma Entandrophragma utile populations, making very long rotation cycles inevitable.
In one set of animals, cimetidine in saline was simultaneously perfused intragastrically for 2 h at the rate of 2. Help us share the wonders of the natural world.

The grain is slightly interlocked, texture moderately fine.
Seeds 8—11 cm long including the large apical wing, medium to dark brown. The wood is moderately heavy; soft to moderately hard; moderately durable, being moderately resistant to powder-post beetle, pinhole borer, termite and marine borer attacks.
Germination utiel 13—19 days after sowing. The seedlings are physiologically well adapted to heavy shade and make efficient use of low light intensities – they usually die when growing under full light conditions[ ].
Properties The heartwood is reddish brown to purplish brown, and distinctly demarcated from the pinkish white to pale brown, up to 6 cm wide sapwood.
The wood kiln dries satisfactorily, but material with much interlocked grain may give difficulties.
