Productive potential of Tectona grandis in Midwest Brazil

Abstract

This study aimed to assess the productive potential of teak plantations in the state of Mato Grosso, Midwest Brazil. We modeled the mean annual increment at the age of 12 years (MAI12) as a function of climatic, edaphic and physiographic variables using artificial neural networks (ANN). The ANNs were shown effective in modeling the mean annual increment, despite of some inconsistences found for areas for which part of the environmental information was not available. The greatest proportion of the land covered by our study (62%) presented moderate productivity, ranging from 10.24 m3 ha-1 year-1 to 28.76 m3 ha‑1 year‑1 MAI12. The highest (MAI12 > 28.76 m3 ha-1 year-1) and the lowest (MAI12 < 10.24 m3 ha‑1 year‑1) productivity areas accounted for 18% and 20% of the study area, respectively. Studies comprising a more comprehensive coverage of the teak production areas are encouraged in order to improve estimation accuracy.

Application of Near-Infrared Reflectance Spectroscopy for Predicting Damage Severity in a Diverse Panel of Tectona grandis Caused by Ceratocystis fimbriata

“…Furthermore, the significant effects of genotype on these traits confirm that the genetic diversity present in the teak panel is a determining factor in the variability of these traits. The significant differences observed between the genotypes for each trait suggest that these traits could be potentially used in breeding programs to select for improved resistance to Ceratocystis wilt, as well as for increased early growth [ 7 , 21 ].…”

“…In Brazil, some of the most sought-after tree species include eucalypts, pine, black wattle, rubber tree, parica, Populus, and teak. Among these species, the area under teak plantation is increasing in Brazil, in order to obtain high-quality wood and to target the international wood market for export purposes [ 7 ]. Teak plantations are mainly found in the Midwest region of Brazil, with the state having the largest teak plantation of about 50,000 hectares, due to the favorable climatic conditions for future expansion.…”

Manejo de teca para produção de madeira de qualidade e entrada precoce de gado no sistema silvipastoril

“…No Brasil, o estado do Mato Grosso tem o potencial para a produção de teca devido aos fatores climáticos e edáficos (MEDEIROS et al, 2019a(MEDEIROS et al, , 2019b. Atualmente, estima-se que existam no estado de Mato Grosso acima de quatro mil hectares implantados com o sistema silvipastoril com a teca como componente arbóreo.…”
