Introduction Koa (Acacia koa) is currently the most important commercialized hardwood in Hawai'r's forests. A sustainable supply of koa will depend on reforestation with the best adapted seed sources and perhaps with vegetatively propagated cultivars having unique traits. At present, koa forests are in a serious state of decline, and improvement appears warranted if sustainable supply is to be ...

The present paper is about the species composition, diversity, equitability, richness and concentration of dominance of tree species along an altitudinal gradient of District Dir Lower Hindukush range of Pakistan. A total of 15 stands in Monotheca buxifolia (Falc.) A.D forests were analyzed at an elevation of 1370m to 1670m asl. The vegetation analysis showed that a total of six tree species ex...

Present studies report the experimental results on the dielectric and attenuation parameters for leaves of two different tree species at X-Band microwave frequency, 10.5 GHz. Leaves of two different tree species viz., Azadirachta indica (Neem) and Acacia indica (Babool) have been used in these measurements. Complex dielectric constants of these tree leaves have been measured by using waveguide ...

Study was aimed to evaluate the possible antisecretory and antiulcer activity of crude bark extract of Acacia catechu and its action against indomethacin an non steroidal anti inflammatory drug (NSAID) plus pyloric ligation induced gastric ulcers in rats. Administration of crude extract of Acacia catechu (400mg/kg/day p.o.) significantly reduced ulcer index when compared with indomethacin induc...

The immunomodulatory effect of aqueous extract of Acacia catechu commonly known as Katha or Karangali was studied at two doses of 5 mg/kg and 50 mg/kg orally. The effect was studied in neutrophil adhesion test, mice lethality test, carbon clearance assay, cyclophosphamide induced neutropenia, serum immunoglobulin levels and the heamagglutination test. Acacia catechu extract showed an increase i...

Carbon sequestration potential of Eucalyptus camaldulensis Dehnh and Acacia salicina Lindl planted in 1980 was studied at the age of 30 years in the elevation plain areas of Iran. Two station of this plantation in province were selected the sample plots and the diameter at breast height of all trees was measured. At least, there trees from each diameter class were randomly selected and cut and ...

This study conducted during the season 2017 at ED-Duem Locality which is laid Northern White Nile State of Sudan, main objectives this was measurement, listing all acacia raddiana tree sites their assessed physical characteristics height, diameter breast height and were account abundance, dominance, survival % natural regeneration as species. The researcher used systematic circular sam...
