Context

With India managing 35% of the world’s planted teak forests, it plays a key role in the global teak market. However, natural teak productivity is low, and tissue-cultured teak is being explored as a viable solution.

Challenges in Conventional Teak Propagation

Challenge	Explanation
Seed-based propagation	Low fruit yield, poor seed viability, low germination rates
Vegetative methods	Rooting, grafting, and budding have poor success rates, especially in mature trees

Tissue Culture as a Potential Solution

Feature	Benefit
Genetically uniform saplings	Consistent growth and quality
Disease-free plants	Reduced mortality and better resilience
Faster maturity claims	Claimed harvesting within 8-12 years

Teak (Tectona grandis)

Teak is a tropical hardwood tree species native to South and Southeast Asia.

Known as the King of Timbers it is prized for its durability, strength and natural resistance to water, pests and decay.

Teak is a deciduous species and one of the most valuable timbers in global trade.

Botanical Features

Feature	Description
Scientific Name	Tectona grandis
Family	Lamiaceae (earlier Verbenaceae)
Type	Deciduous hardwood tree
Height	Up to 30–40 meters
Leaves	Large, papery, with rough surface
Flowers	Small, white, fragrant
Fruit	Drupe with woody outer covering
Lifespan	Can live over 100 years

Natural Habitat & Distribution

Native regions: India, Myanmar, Thailand, Laos.

Major teak-growing states in India

Madhya Pradesh

Maharashtra

Odisha

Karnataka

Kerala

Tamil Nadu

Andhra Pradesh

India has about 8.9 million hectares under teak forests and plantations—around 35% of global teak forests.

Climatic and Soil Requirements

Parameter	Requirement
Rainfall	1200–2500 mm annually
Temperature	20–40°C
Soil type	Deep, well-drained loamy or alluvial soils
Altitude	Up to 1200 meters above sea level
Light	Requires full sunlight (heliophilic species)

Economic Importance

High commercial value in:

Shipbuilding

Furniture and cabinetry

Flooring

Veneer and decorative paneling

India is both a producer and importer of teak wood due to rising demand and legal restrictions on harvesting from natural forests.

Teak fetches premium prices due to its:

Natural oils (prevent rotting)

Dimensional stability

High tensile strength

Ecological Significance

Aspect	Role
Biodiversity	Supports understorey vegetation and soil microflora
Soil binding	Helps prevent erosion on slopes
Carbon sink	Moderate potential for carbon sequestration
Native species	Maintains ecological balance in mixed forests

Methods of Teak Propagation

Method	Pros & Cons
Seed-based	Low germination rate, variable genetic quality
Clonal/vegetative	Grafting, cutting—limited success in old trees
Tissue culture	Uniformity, fast growth, disease-free—but variable results and high cost

Challenges in Teak Cultivation

Slow growth rate in traditional plantations (20–30 years to mature)

Illegal felling and timber smuggling

Fire hazards in dry deciduous areas

Pest and disease issues, e.g., teak defoliator (Hyblaea puera)

Genetic degradation due to unscientific propagation

Policies and Legal Framework

Policy/Act	Relevance
Indian Forest Act, 1927	Governs rights and duties in forest areas
Forest Conservation Act, 1980	Restricts conversion of forest land and felling
National Forest Policy, 1988	Encourages farm/agroforestry; restricts commercial felling in natural forests
National Agroforestry Policy, 2014	Promotes tree cultivation outside forests (ToF) including teak
Ease of Tree Felling Laws	Teak felling still regulated in many states (e.g., transit permit system) Green felling in government forests prohibited under Forest Conservation Act (1980) and National Forest Policy (1988), increasing reliance on private plantations
