The dominance of Gmelina arborea and Tectona grandis in the study area invariably point to the suitability of the soil conditions which favoured the high frequencies of establishment of these species. Also it portends their inherent ability to adapt persistently with high ecological tolerance. The year-to-year variations in flowering, pollen and fruit production in ten Gmelina arborea individuals in a natural forest were observed over a period of five years, −, and pollinator visits were observed closely over two years, and
Gmelina arborea, locally known as Gamhar, is a fast growing deciduous tree, occurring naturally throughout greater part of India at altitudes up to 1, meters. It also occurs naturally in Myanmar, Thailand, Laos, Cambodia, Vietnam, and in southern provinces of China, and has been planted extensively in Sierra Leone, Nigeria, Malaysia, and on. ). However, very limited studies have been carried out on cement site, including production externalities and profitability of crop (Tijani et al., ) and growth of Phaseolus vulgaris L. cv. (Ade-Ademilua and Umebese, ) in Nigeria. Extensive literature search showed that no apparent studies were undertaken on.

Gmelina arborea Roxb (Verbenaceae) is a well-known medicinal plant in the Ayurveda, an ancient Indian system of medicine. The roots, leaves, flowers, fruits and bark are used for treating different ailments in traditional medicine.
The literature suggests use of the plant in treatment of scorpion sting, snake-bites, and diabetes. The plant is anthelmintic and used.

@ 2 Forestry and Forest Products Research Centre, CSIR Natural. A survey of the production and marketing system of Gmelina arborea (Roxb.) in smallholder farms was conducted in Claveria.
Survey respondents included farmers, who planted and have undertaken their first harvest of Gmelina trees, and sawmill operators in the nearby coastal towns who are processing and marketing Gmelina logs. Average farm size in the study was ha.
However, this tool has not been duly utilized in many forest plantations, especially in Nigeria. Thus, this article presents the effectiveness of using the Johnson S B function for modeling diameter distributions of a Gmelina arborea plantation in Omo Forest Reserve, Nigeria.
Fifty plots of ha were randomly selected across three age series. 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. The study was conducted in Nazareth High School Compound, Imeko in Ime-ko/Afon Local Area of Ogun State, Nigeria.
Construction of hives Erythrophleum suaveolens, Gmelina arborea Vitex do-and niana wood samples of 1x12x12 and 2x6x12 sizes were purchased from Emilandu sawmill in Imeko. All pur-chased wood samples (lumbers) were free of. Uses, Benefits, Cures, Side Effects, Nutrients in Gmelina.
List of various diseases cured by Gmelina. How Gmelina is effective for various diseases is listed in repertory format. Names of Gmelina in various languages of the world are also given.
talking drum making. Gmelina arborea is considered as one of the most widely cultivated and distributed exotic species in Nigeria and many people have benefited from the wood. Hence, this study explored the suitability of G. arborea wood as substitute for indigenous Cordia millenii for production of talking drums in Ibadan.
Distribution and habitat. Gmelina arborea grows naturally throughout India, Myanmar, Thailand, Laos, Cambodia, Vietnam and in southern provinces of China. It is found at altitudes from sea level to 1, metres (5, ft). Since the s, it has been introduced extensively as fast-growing timber trees in Brazil, Gambia, Honduras, Ivory Coast, Malaysia, Malawi, Nigeria, the.

The initial blood glucose levels of the diabetic rats selected for the study were in the range of to mg/ ml.
At the end of the experiment (15th day) blood glucose level was ± in the diabetic mice treated with mg/kg body weight of the alcoholic extracts of the stem bark of Gmelina arborea. The observed. A recent trend in Nigeria is towards the production of sufficient pulpwood, fuel, poles, and timber.
Hence, state forestry services have set up annual planting targets of 20, and 6, ha for Gmelina arborea and teak, respectively. Similarly, the recent food crisis in Nigeria has become a major concern in official circles. Gmelina arborea for this study is justified by its unique importance in the pulp and paper mills as well as the indispensability roles it plays in forest soil conservation and ecosystem management.
Therefore, the study aimed to develop and validate a crown width prediction models for sustainable management of Gmelina arborea within the.Onyekwelu, J.C, Choosing appropriate index age for estimating site index of Gmelina arborea timber plantations in Oluwa forest reserve.
