Plant tissue culture is an important tool in forestry and biotechnology with its substantial improvements in plant propagation. The development of tissue culture is started with Haberlandt’s totipotency theory and the mid-20th century discovery of plant growth regulators which transformed methods of plant multiplication. The utilization of tissue culture in the micropropagation of teak (Tectona grandis L.) is a valuable hardwood species used for building, furniture and lumber. Through the production of genetically identical seedlings with desired characteristics including disease resistance, rapid development and high wood density. Tissue culture overcomes the drawbacks of traditional teak propagation which includes low germination rates, pest susceptibility and slow growth. This method supports conservation and sustainable forestry practices by providing a few benefits such as disease-free plant production, quick multiplication and year-round availability. Highly expensive, somaclonal fluctuation, contamination dangers and acclimatization hurdles are still major drawbacks. The importance of tissue culture in genetic improvement which allows for the preservation of elite genotypes and the creation of faster-growing, pest-resistant teak varieties is also examined in the research. Tissue culture is still a vital technique for large-scale teak production, reforestation and biodiversity protection despite its difficulties. It provides a revolutionary approach to commercial forestry and environmental sustainability.
