| Summary: | Carbon sequestration into plants biomass, especially in fast growing trees is an easier and economically way for
dropping off Co2 from atmosphere. This study was carried out in order to investigate above-ground biomass of
white poplar (Populous alba, L.) plantations that was planted in four different plant spacing (0.5 × 0.5, 1 × 1, 2 × 2
and 4 × 4 m) in Chaharmahal and Bakhtiari province in west of Iran. Selecting the trees was according to diameter
classes. After inventory, 10 trees were selected from each density at one hectare area. The tree’s characteristics
including diameter at breast height (DBH), total height, and crown diameter measured. Then measured trees felled
down in order to measure the wet and dry weight of different organs including (whole tree, trunk, main branches,
twigs and leaf).The regression analysis was applied to find out a relationship between mass production and poplar
characteristics and to develop different allometry models between different organs and their carbon sequestration
ability. The results showed that the independent DBH factor in P. alba, demonstrated high correlation against all
the dependent variables. Height of trees also creates the allometric equations with average accuracy (0.30 - 0.81)
against all the dependent variables. The crown diameter in dependent variable almost creates weakest equations.
The result also indicated that there is no significant difference among equations of different planting spaces. |
