A Half-yearly Peer Reviewed Journal of Bangladesh Forest Research Institute
Two provenance trials of Pinus caribaea var. hondurensis were established in randomised complete block design in 1983 and later in 1984 at Keochia Silviculture Research Station, Chittagong, Bangladesh. It was observed that there was no significant difference among the provenances in respect of survival percentage, height and diameter growth and volume yield till December, 1989. All the provenances are doing well in the area. The mean height, diameter at breast height and volume yield per plot of 148.84 m2 ranged from 9.5-10.4 m, 12.5-13.8 cm and 1.242-1.663 m3 respectively for the 1982 trial at the age of 7.5 years. The corresponding data for the 1984 trial at the age of 5.5 years were 4.2-5.4 m, 6.0-7.7 cm and 0.102-0.300 m3 respectively.
