Development of Organic Carbon Sequestration Models for Dipterocarpus Turbinatus,
Acacia Auriculiformis and Eucalyptus Camaldulensis and their Potentialit 450
the trees. In Dipterocarpus turbinatus leaf organic carbon (7.27% of the total organic carbon) is
comparatively higher than that of the Acacia auriculiformis (4.34% of the total organic carbon) and
Eucalyptus camaldulensis (5.73% of the total organic carbon). Organic carbon percentage of different
plant components are shown in ‘Figure 1’.
Figure 1: Organic carbon percentage of different plant components.
Different tree species has shown variation in proportionate carbon accumulation in different
components of them (Figure 1.). Among the components main bole contributed higher carbon
accumulation for the studies three species.

Relationship between diameter at breast height (cm) and Total organic carbon
content (kg) of the growing trees
The regression equation for Dipterocarpus turbinatus calculating total organic carbon content
(kg/tree) was found Y= -10.219 +3.601X. Here Y-represents the total organic carbon content of tree
and X represents the diameter at breast height (cm). From the equation it implies that the total organic
carbon content is increased by 3.601 kg for per unit increase in Diameter at Breast height. The
coefficient of determination (r 2 ) is 0.9629 and the relationship was significant at P>0.01 The regression
equation for Acacia auriculiformis calculating total organic carbon content (kg/tree) was found Y= -
59.204+8.487X. Here Y represents the total organic carbon content of tree and X represents the
diameter at breast height (cm). The regression line is presented in the graph. From the equation it
implies that the total organic carbon content is increased by 8.487 kg for per unit increase in diameter
at breast height. The coefficient of determination (r 2 ) is 0.948 and the relationship was significant at
P>0.01. The regression equation for Eucalyptus camaldulensis calculating total organic carbon content
(kg/tree) was found Y= - 10.113 + 5.421X. Here Y represents the total organic carbon content of tree
and X represents the diameter at breast height (cm). The regression line is presented in the graph
(Figure 2). From the equation it implies that the total organic carbon content is increased by 5.421 kg
for per unit increase in Diameter at Breast height. The coefficient of determination (r 2 ) is 0.889 and the
relationship was significant at P>0.01 .
