Reynolds and Lawson () concluded that the heating value of Gmelina wood was less than that from the local eucalypts. Although the calorific values of the samples studied were almost identical ( mcal/kg and respectively), the DM contents were 45 and 56%. The study evaluated the kiln drying of mm thick Gmelina arborea Roxb. lumber using conditions based on changing shrinkage rates following the procedure developed by Fuller under US Patent No. 5,, dated 23 February

Scaling up of Ghamar (Gmelina arborea Roxb.) based agroforestry in India has a prime concern as it is a native species which has potential to replace and act as a substitute for other exotic timber trees in the country. Gmelina is gaining momentum at the present time; besides fulfilling the demand of wood and timber in the current scenario of industrial agroforestry and also fulfilling other Cited by: 1.

More than 60 Gmelina arborea provenance trials were established in the mid-seventies as a joint effort between 20 countries, mainly outside the natural distribution areas of gmelina.
Results from 27 of these trials are presented in this article focusing on differences between seed sources in growth rate, bole quality and wood density.

By Umana, E. J, Akwaji, P. I., Markson, Size: KB. Abstract. Gmelina arborea (Family: Verbenaceae) is considered as a useful multi-purpose species.
The wood of Gmelina is used as raw material for cellulose, and it has received attention as a source of good quality pulp, medium density fiberboard and plywood because of its beautiful white color and stronger fiber.
The aim of this study was to determine the fiber dimensions of Author: J. Soosai Raj, A. Mayavel, V. Mutharaian, A. Nicodemus. The densities of Gmelina arborea and Leucaena Leucocephala were kg/m 3 and kg/m 3 respectively.
Modulus of Rupture (MOR) The mean values for MOR ranged from N/mm 2 to N/mm for Gmelina arborea and N/mm 2 to N/mm 2 for Leucaena Leucocephala. Wood density has effect on the reactions of boards to bending test. Gambhari (Gmelina arborea) - Practical Uses, Benefits and Dosage Description of Plant.
Gmelina arborea is a deciduous trees that attains height up to 20 meters. The bark is grayish white colored, which exfoliates in thin flakes. The leaves are simple, opposite and heart shaped tapering towards the apex with length of cm and breadth of 8.
Plant Description: Gmelina arborea is a medium-sized tree up to 60 feet high with tomentose branchlets. Leaves: inch long, broadly ovate, acuminate, entire ; upper surface glabrous when mature, lower persistently clothed with fulvous stellate hairs, base cordate or truncate and shortly cuncate; petioles inch long, cylindric, puberulous.

Gmelina arborea is a multipurpose tree species native to Asia. This tree can be propagated by seedlings, rooted cuttings, and grafting. Small tree planting programs with limited budgets tend to propagate by seedlings, and larger or industrial plantation projects with breeding programs propagate by rooted cuttings.
Details about these propagation methods are by: 6. is a platform for academics to share research papers. AbstractGmelina arborea Roxb. (gmelina) was introduced in Costa Rica in the late s. At the present time, gmelina is the most widely planted tree species in Costa Rica.
According to estimations by the Food and Agriculture Organization (FAO), there are ab ha reforested with gmelina in the country.
This forested land has the potential of producing overcubic meters of timber.Study on foliar micro morphology of Gmelina arborea Roxb.: A clonal identification against Craspedonta leayana gave the genus Gmelina as an advanced entity.
