Abstract
The effects of site and clone origin on basic wood density of teak (Tectona grandis) were studied in 18 clones vegetatively propagated from plus trees and grown at 2 locations in Kerala, India. Wood density was measured in 14 yr old samples taken from the mature outermost growth increment at breast height showed that site had a highly significant influence on wood density, while place of origin of clones had no effect. No evidence of any interaction between site and clones could be detected
