“…This result may be related to the low requirement of the micronutrient by the African mahogany in its initial phase of development. A similar result was observed by Corcioli et al (2016) in another African mahogany species (Khaya ivorensis A. Chev) where the omission of zinc in fertilization did not influence the plant growth in the early stages. Evaluating the growth of Australian cedar under boron and zinc supplementation, Carmo et al (2010) concluded that Zn doses did not influence plant height and diameter during the 3-month experimental period.…”

“…In addition to macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, carbon, oxygen, and hydrogen), it is also necessary to consider micronutrients which, although required in small amounts, they are fundamental to the performance of main cellular metabolic functions (Corcioli et al, 2016). Thus, the adequate supply of these nutrients is a key point for plant growth and development, including for forest species.…”

African mahogany (Khaya senegalensis A. Juss) has been an important option to supply the increasing demand for noble forest products for the Brazilian furniture industry. In the present study, the objective was to evaluate the initial development of mahogany plants in response to different doses of zinc. The experiment was carried out inside a greenhouse, in the experimental area of the State University of Goiás, Ipameri Campus, in 7 dm 3 plastic containers, and using soil samples, identified as Dystrophic Red-Yellow Latosol (Oxisol), as substrate. The experimental design was completely randomized, with five treatments and five replications, totaling 25 experimental units. The treatments consisted of five Zn concentrations: 0, 2.5, 5, 10 and 20 mg dm -3 , obtained by zinc sulfate fertilizer. At 150 days, the measurements of the plant height, the root crown diameter, dry matter mass of leaves, stem, root and total were evaluated. The tested increasing zinc doses did not promote increased plant growth. African mahogany presented low zinc requirement in the early stages of development for the studied edaphoclimatic condition, and no application of zinc via fertilizers was required. This fact may resulting from the natural concentration of 0.2 mg dm -3 of Zn in the used soil, which was enough to supply the nutritional demand of the plants in the first five months of development.

“…However, for African mahogany, reduction in precipitation period was probably the limiting factor responsible for its low performance. This is true considering PINHEIRO et al (2011) andCORCIOLI et al (2016) observation that this species needs deep soils with high fertility and average annual precipitation of 1300 to 1800mm for healthy growth.…”

Silvicultural performance of forest species introduced in integrated livestock forest system in Lavras, MG, Brazil

et al. 2017

The objective of this study was to evaluate the silvicultural performance of four forest species introduced in a setting for integrated livestock forest (ILF) in a pasture in Lavras, Minas Gerais, Brazil. The species included were the Australian red cedar (seminal and clonal), African mahogany, teak, and guanandi. A split plot scheme with a randomized complete block design comprising four replicates and 48 plants per plot, was used in the following arrangement: (3(3x2) +7x2) m. The evaluation times (12, 18, 31, 36, and 43 months after planting) corresponded to the subplots. Performances of all four species were evaluated on the basis of their survival rate, height (H) and diameter at breast height (DBH). Based on the performance of the species with regard to these parameters, the clonal Australian red cedar showed a greater growth in DBH and height in the ILF setting as compared to the other species, which indicates it to be a suitable species for the region of Lavras, MG as long as its survival control occurs in the implantation phase.

“…Pesquisas de diferentes naturezas utilizando a espécie estão se iniciando no Brasil (Falesi & Baena, 1999;Gasparotto et al, 2001;Poltronieri et al, 2002;Castro et al, 2008;Gomes, 2010;Tremacoldi et al, 2013;França et al, 2016;Corcioli et al, 2016). Siqueira et al (2002), ao avaliarem o comportamento de plantios florestais utilizando 18 espécies exóticas em Sergipe constataram que o mogno africano possuiu crescimento lento quando comparado às demais espécies, não sobrevivendo às condições da baixada litorânea.…”

RESUMOO setor florestal brasileiro está em plena expansão e com um aumento gradativo de investidores florestais optando pelo cultivo de espécies de madeira nobre. O mogno africano (Khaya spp.) é uma espécie que vêm se destacando na preferência dos empresários como opção no investimento florestal. Porém, estudos e pesquisas sobre a espécie, principalmente no Brasil, são escassos. Assim, a presente revisão procurou reunir diversas fontes de publicação, nacionais e internacionais, abordando aspectos históricos do mogno, buscando aclarar as características da espécie e a experiência de outros países no manejo dessa cultura.Palavras-chave: mogno africano (Khaya spp.), plantios florestais, manejo florestal.African Mahogany (Khaya spp.) Cultivation and the Increase of the Activity in Brazil ABSTRACTThe Brazilian forest sector is fast growing with a gradual increase of forest investors choosing valuable hardwood species for tree crops. African mahogany (Khaya spp.) is a species that has been preferred by many entrepreneurs as a forestry investment. However, there are few studies and research on the species, especially in Brazil. Therefore, this review aimed to bring together diverse sources of national and international publications, discussing the history of the mahogany and characteristics of the species as well as the experience of other countries on the management of this crop.
