“…In vitro propagation has been successfully applied in Tectona grandis and it has become an alternative tool to overcome some problems occurring in sexual regeneration (Widiyanto et al 2005). Regenerative organs such as pre-existing shoots, meristem shoot-tips, nodal segments or seedling organs have been widely used as explants (Gupta et al 1980, Mascarenhas et al 1987, Apavatjrut et al 1988, Devi et al 1994. Adventitious shoot formation from callus tissues has been proposed for the regeneration of genetically engineered tissues of many species (Siemens & Schieder 1996, Tawfik & Noga 2001, Lee & Pijut 2017.…”

In the present study efforts were made to enhance in vitro seed germination and achieve shoot organogenesis through different explants of Tectona grandis, a hardwood timber species known throughout the world for its high-value wood. Seed germination was significantly affected by seed inoculation on different strengths of MS medium and different GA 3 concentrations. Different strengths of MS media combined with different GA 3 concentration significantly affect seed germination in vitro. Maximum seed germination (96%) was obtained on 0.4% GA 3 combined with half strength MS medium. The effect of types of explants (leaf, internode, hypocotyl and root of seedlings), different concentrations of thidiazuron (TDZ) (0.1, 1.0 and 10 μM) and auxins (IBA, IAA and NAA) on callus induction and shoot formation was investigated. After 30 days of inoculation, it was observed that explant type had a significant effect on callus formation. Maximum callus was obtained on internode explants (56.17%) which were statistically on par with callus obtained on leaf explants (54.32%). The effect of TDZ on callus and shoot formation was also observed. TDZ with higher concentration (1 μM) gave maximum callus (48.6%). Whereas lower concentration of TDZ (0.1 μM) was effective for shoot formation from both internode and hypocotyl explants. IAA and NAA were also helpful in shoot formation whereas IBA retards shoot formation. For shoot organogenesis internode was found to be most responsive explant type followed by hypocotyls and leaf. Roots were found to be the least responsive explant.

“…Currently, mass propagation of selected teak clones is possible through in vitro multiple shoot production. Regenerative organs such as pre-existing shoots, meristem shoot-tips, nodal segments or seedling organs have been widely used as explants (Gupta et al, 1980;Mascarenhas et al, 1987;Apavatjrut et al, 1988;Devi et al, 1994).…”

A procedure was developed to induce shoot organogenesis of teak (Tectona grandis L.f.) callus cultures. Calli were induced from internodal segments on woody plant medium containing 1.0 µM thidiazuron in combination with 0.01 µM indole butyric acid. Results showed that compact callus, with white to light yellow nodular structures on its surface, were produced in four weeks. The most regenerative callus was noted as the compact callus with light yellow or light green color. Shoot organogenesis was induced on medium containing 10.0 µM benzyl adenine in combination with 1.0 µM gibberellic acid. Adventitious shoots proliferated from the surface of regenerative compact callus after three subcultures. Regenerated shoots were propagated on shoot multiplication medium with the addition of 10.0 µM BA. Most elongated shoots were rooted in a soil-sand mixture medium (1:1), and were established under greenhouse conditions.

“…f., popularmente conhecida como teca pertence a família Lamiacea e ocorre naturalmente na Índia, Myanmar, Tailândia e Laos. Esta espécie apresenta um alto valor madeireiro, sendo considerada uma das mais valiosas do mundo (MASCARENHAS et al, 1987;OLIVEIRA et al, 2007;TECA, 2007). Atualmente, a tora de desbaste com diâmetro variando de 15 a 20 centímetros chega a ser comercializada a valores entre US$ 700 e US$1200/m 3 e é considerada uma das cinco espécies tropicais arbóreas mais plantadas no mundo (DAH e BAW, 2001;BHAT e MA, 2004).…”
