“…Sistem stek pucuk merupakan salah satu cara perbanyakan vegetatif yang efisien dan berbiaya murah. Berbagai jenis Meliaceae telah sukses diperbanyak dengan cara stek, contohnya Khaya anthotheca, K. ivorensis, K. senegalensis, Entandrophragma angolense, dan E. utile (Barbosa Filho et al, 2016;de Vasconcelos, Valeri, Martins, Biagiotti, & Perez, 2016;Owusu, Opuni-Frimpong, & Antwi-Boasiako, 2014;Ky-Dembele et al, 2011;Opuku, Opuni-Frimpong, & Adomako, 2008) Keberhasilan stek dipengaruhi oleh faktor internal (tanaman) dan eksternal (lingkungan). Faktor bahan tanaman ditentukan oleh karakter genetik, kandungan cadangan makanan, ketersediaan air, hormon endogen, tingkat juvenil dan umur tanaman.…”

Mahogany (Swietenia macrophylla) plantations are threatened by shoot borer (Hypsiyla robusta), therefore the resistance of mahogany plants to shoot borer become a priority for the establishment of mahogany plantations. Elite trees that have resistance to shoot borer could be found through genetic selection of mahogany population in the field. Propagation of these elite trees should be prepared by vegetative propation to ensure that the mother plant's characteristics were inherited. Vegetative propagation of mahogany was conducted by cuttings. The experiment design consisted of split plot in randomly group with 4 medias and 3 IBA treatments; repeated 3 groups with 15 seedlings per experimental unit. Cutting materials were collected from one year old seedlings. Successful cutting was determined by these parameters: percentage of rooted cuttings, numbers of root, root length, shoot length, root biomass, and shoot biomass. The results showed that media factor had significant effect to cuttings, while soaking cutting material in growth regulators gave no significant effect. The highest percentage of rooted cutting was produced by media cocopeat+husk (2:1, v/v) by 93%. The greatest number of roots were generated using rice husk and coconut+husk (2:1, v/v) by 4.5 strands of roots. The longest root was produced using media soil by length 86 mm. Based on these cutting parameters, cocopeat+husk is the most optimal media for mahogany cuttings.

“…In addition to plantations, it is generally accepted that restoration in natural forests is indispensable for mahogany conservation and sustainable utilization (Chaikaew et al 2020). However, promoting the natural regeneration of this species remains a major challenge worldwide (Ward et al 2008; Owusu et al 2014). Auto‐ecological research is thus necessary to strengthen capabilities to enhance the natural regeneration of K. anthotheca (Ward et al 2008; Opuni‐Frimpong et al 2008b).…”

Restoration of high‐value timber trees in logged tropical forests is indispensable as a conservation strategy and for the enhancement of ecosystem services. Khaya anthotheca is a mahogany tree species of major restoration importance in Uganda. However, the factors affecting the natural regeneration success of this species are poorly understood. We determined the effect of selected site conditions on the abundance of K. anthotheca regeneration in the Budongo Forest Reserve. Two hundred and four 1,000 m2 inventory plots, each nested with four 4 m2 subplots, were systematically established in logged and unlogged sites within the study area. All trees greater than or equal to 10 cm DBH and natural regeneration (<10 cm DBH) were identified and recorded in the plots and subplots, respectively. We characterized plots by the density of conspecifics, light availability, ground cover of undergrowth, litter depth, soil pH, and basal area. Regression models were used to evaluate the variables that influenced regeneration abundance and occurrence. The density of adult conspecifics and soil pH were important. Regeneration abundance and occurrence increased with increasing density of adult conspecifics and decreased with increasing soil pH. Our results highlight that in addition to seed availability, soil pH was important for successful regeneration. This is one of the first K. anthotheca‐specific studies to evaluate more than a few environmental factors influencing the density of its naturally established seedlings in tropical African forests. The abundance and distribution of adult conspecifics in the canopy and soil pH should be considered in K. anthotheca restoration plans.

“…At the crux of the matter, post‐logging regeneration is only poor (Hall et al., 2003; Makana & Thomas, 2006; Mwima et al., 2001). Boosting the regeneration of mahogany species globally is of great urgency to foresters and conservationists (Owusu et al., 2014), and increased knowledge of fruit or seed production of the species is needed.…”

Restoring valuable timber trees is a necessary part of regaining many ecosystem services and products provided by degraded tropical forests. However, knowledge of seed production, a regeneration prerequisite, is limited for many tropical timber tree species. We studied the fruit production of African mahogany (Khaya anthotheca) in a semi‐deciduous rainforest in East Africa, to provide information for ecological restoration programs. First, we quantified population variability and synchrony in fruit production. Then, we assessed how reproductive status and output were influenced by tree size, neighbourhood crowding, exchangeable cations, liana presence, and crown exposure. We found fruit production at the population level was weakly synchronised, with high interannual variability at the population and individual levels. Tree size determined reproductive status. Individual quantity of fruit produced increased with tree size but decreased with neighbourhood crowding. Our results indicate that K. anthotheca does not meet the criteria for mast fruiting. Our findings suggest that reproductive output in mahogany is regulated by tree size and competition. In addition to active protection, thinning to reduce competition around seed trees may boost fruit production at the individual tree level to provide seed for forest enrichment.
