Clones production of Tectona grandis

Abstract

Tectona grandis is a woody forest species of commercial interest that presents extensive plantations in the world, mainly due to the wood to be destined for several purposes, including noble applications which elevate their price in the market. Nevertheless, despite the importance, there is a lack of research regarding the clone multiplication in a large scale of selected genotypes, limiting progress in the improvement of the species. This review aims to perform a literature review of the main scientific methods used to obtain clones of species, such as the processes of macropropagation and micropropagation, and present perspectives and future trends for the application of new cloning techniques aiming for large scale for clones production. According to the literature, some techniques such as minicutting, autotrophic cultivation and synthetic seeds may be applied to T. grandis for clones production. Further scientific studies are however needed in order to prove the viability to produce clones. The improvement aiming the disseminating such techniques can minimize costs, shorten production stages and consequently, reduce the cultivation time in the laboratory.
