Abstract

Carbon sequestration through trees is one of the most important strategies to mitigate the carbon emission. The present study was conducted in Khorramabad Agricultural Orchard as randomized complete block design. In each experimental unit, three five-year-old trees were investigated in two groups and 12 poplar colonies or cultivars in three replications. Duncan multiple range test was used to find the mean comparison of the treatments and T test was applied to observe the differences between two groups. The results showed that there is a significant difference in the increment rate and amount of carbon sequestration in the two poplar groups (P<0.01). P. nigra 42.53 revealed the maximum increment in the closed crown group to be 2.6714 m3, and also the highest annual sequestration as 2460.8 kg/ha. In open crown group, the highest increment and carbon sequestration were observed in P.X Pacher to be3.0618 m3 and 1987.909 kg/ha, respectively. Additionally, the open crown group had a higher increment rate compared to the closed crown group. However, there was no significant difference between the two groups in terms of the amount of carbon sequestration. It can be interpreted that the density of open crown group is less than the closed crown one. According to our findings, further studies on carbon sequestration of various tree species and afforestation with fast-growing species with high carbon storage potential is recommended to control the concentration of CO2 in the atmosphere.
