Mahogany: Tree of the Futureffer familiar problems of misinformation and missing information. The natural range is vast, and, although the species is not on the verge of extinction, genetic erosion has been alleged. Sustainable exploitation is hampered by inadequate knowledge of its regeneration ecology and the all too common practical problems of rule enforcement.作者: 鋼筆尖 時間: 2025-3-22 20:31
Introduction to Parallel Processinger low light. Nitrogen concentration was significantly higher in low-light seedlings, but because of the larger area: weight ratios of low-light leaves, the N concentration per unit area was higher under the intermediate- and high-light (~70mmolm.) than in the low-light treatment (55mmolm.).作者: STENT 時間: 2025-3-22 22:42

Stand structures and growth curves for all three of the associated species suggested that conditions created by episodic flooding and deposition also might improve their regeneration.作者: 文藝 時間: 2025-3-23 04:02 作者: 使殘廢 時間: 2025-3-23 08:18 作者: 我怕被刺穿 時間: 2025-3-23 13:36 作者: Keratin 時間: 2025-3-23 16:59 作者: 競選運動 時間: 2025-3-23 20:20
Genetic Variation in Natural Mahogany Populations in Bolivia from Bolivia. We sampled seeds from individual maternal trees in four mahogany populations separated by as much as 100km. Data were analyzed based on estimated maternal genotypes and on randomly drawn progeny arrays from known mothers.

Silvicultural Systems for Big-Leaf Mahogany Plantationstle account of the long-term development of stands or subsequent rotations and cannot properly be called silvicultural systems. As existing plantations begin to mature, the need to consider establishing the next rotation grows, and, therefore, the need to adopt a suitable silvicultural system.

Mahogany Planting and Research in Puerto Rico and the U.S. Virgin Islandsmall-leaf mahogany on St. Croix, Virgin Islands, were in about 1790. Big-leaf mahogany was apparently introduced in Puerto Rico in 1904. The Pacific coast mahogany, arriving much later, has not performed well and grows only in research plots.
