CLIMATIC CONDITION It reaches its optimum natural

development climatic conditions of the tropical dry forest formation.

Mean annual temperature of 24°C or higher, mean annual precipitation rates 1000 mm to 2000 mm.

PHYSIOGRAPHIC EDAPHIC AND BIOTIC REQUIREMENTS :

It thrives the moist warm climate Well-drained Deep rich soil It can tolerate altitude about 1000 meters from the sea level .

SILVICULTURAL CHARACTERISTICS Moderate to full demander. It is usually attack by several insects, notably

beetles, from germination upto sapling stages.

Insect damage become insignificant after these stages .

PHENOLOGY It produces a good number of fruit from age 20 years to 40

years and thereafter although there are places where it flowers early but do not develop into full fruit .

losing all or most of their leaves over winter shedding at the flush of new growth in spring. New leaves emerge blood red to pinkish, quickly becoming a

bright, light green and darkening as they mature.

Regeneration

Natural Regeneration

Artificial Regeneration

NATURAL REGENERATION The winged seeds are dessiminated by wind and

germinates easily on favourable site conditions. The seeds losses its viability in a very short period. Moderate openings in the canopy is necessary to

stimulate and growth of the reproduction.

ARTIFICIAL REGENERATION The seeds are sown in nursery beds and

covered with mulch. After 7 to 17 days the seeds germinate

and the mulch is removed. Seeds are sown directly in polybag filled

with forest soil and raised under a shade.

USESThe wood is extensively used for Furniture

CONTINUED Plywood

Paneling, wood carving, barrels, construction work

Toys,musical instruments etc.
