Rekot ak pwodiksyon semans
The tree flowers at the end of the dry season or beginning of the wet season. The seeds are winged and travel by wind. Seed capsules are cut and dried in the sun until they split, then hand shelled. The seeds are often already attacked by insects while they are still on the tree, and undamaged seeds should therefore be selected before sowing or storage. Germination of fresh seed, kept in a very cool environment is high, and can be stored for up to a year in these conditions. Seeds can germinate in full sun as well as in the shade, but natural regeneration may be very sparse in the forest. The seeds can be directly sown in the shade in pots and can be planted in the ground with partial shade after about one year when they are 30-50 cm in height. The wood of this mahogany is soft and easy to work with. It is slightly red and will polish easily to a beautiful shine. It coppices poorly.
Pès ak Maldi
This tree is resistant to the mahogany borer but its shoots are not immune to the Hypsipyla robusta which causes the tree to fork and slow down its growth when shoots are destroyed. Silvicultural techniques, such as overhead shading of saplings, mixed planting and removal of lateral shoots, can reduce damage by shoot borers. Seeds are commonly attacked by seed-boring beetles and eaten by small rodents. Animals, especially rodents will browse on the tender tips of saplings.
