บทคัดย่อ (EN): Since carbon dioxide is a primary greenhouse gas, many scientists argue that the increase in atmospheric carbon dioxide from human activities has resulted in an enhanced greenhouse effect and could result in corresponding changes in global climate, including higher global temperatures. Carbon sequestration, a process that removes carbon dioxide from the atmosphere by locking it transiently could be the only solution to tackle the problem. As far as rubber plantation is concerned, carbon could be sequestered in plant parts, products, litters, debris and soil. In this study total carbon was measured in different plant parts of RRIM 2020 and RRIM 2025, planted in four planting densities; 500, 1000, 1500 and 2000 plants/hectare. The objective ware to evaluate which planting densities could give rise to higher total carbon and which plant parts sequester the most carbon. A summary on total fresh weight (TFW). total dry weight (TDW) and total carbon (TC) gives a general overview on biomass information and pattern of carbon disposition. At 500 plants/ha density, goes larger, the pattern shifted towards clear bole. This gives indication that the tree crown grew bigger in less dense planting in order to maximize the photosynthesis activity, while in more dense planting the competition among trees increases and forces them to grow taller in order to reach for more light source and hence the clear bole mass becomes greater. When plant parts’ total carbon are subjected to the calculation of variance ratio, it was found that the type of clones used in the study did not show any differences in total carbon sequestered in their plant parts. However when densities were made as a source of variance in the analysis, majority of the plant parts were shown to be affected by it. Total carbon in plant parts was shown to be the highest in 500 plants/ha, this is followed by 1000, 1500 and finally 2000 plants/ha. Different pattern was seen only for petiole where the highest total carbon was observed in 1000 plants/ha, followed by 1500, 500 and 2000 plant/ha. Calculation of variance ratio for total carbon in plant parts of each clones and densities showed significantly difference, this means total carbon sequestered in different plant parts was significantly different in the amount. For RRIM 2020 in 500 plants/ha density, the highest TC was seen in large branch, followed by bole, root, small branch, bark, twig. leaf and the lowest in petiole. For 1000 and 1500 plants/ha densities. the highest TC ware shown in bole, followed by root, large branch, small branch, bark, twig, leaf and the lowest in petiole. For 2000 plants/ha density, the highest TC was found in bole, followed by root, bark, twig, small branch, large branch, leaf and the lowest in petiole. Different pattern was documented for RRIM 2025; in 500 plants/ha density, the highest TC was seen in large branch. followed by bole, root, small branch, bark, twig, leaf and the lowest in petiole. For 1000 plants/ha density, the highest TC was seen in bole, followed by large branch, root, small branch, bark, twig, leaf and the lowest in petiole. For 1500 plants/ha density, the highest TC was shown in bole, followed by root, large branch, small branch, bark, twig, leaf and the lowest in petiole. For 2000 plants/ha density, the highest TC was observed in bole, followed by large branch, root, bark, small branch, twig, leaf and the lowest in petiole. Clearer view in the pattern of total carbon sequestered in different densities can be shown through orthogonal polynomial trend analysis calculation, where densities are incremented equally. For clone RRIM 2020, there was no significant trend model for leaf and bole. For petiole the trend was cubic, while for twig, small branch, large branch, bole and root they were all linear model. For clone RRIM 2025, there was no significant trend model for petiole, bole and bark. The pattern was cubic for leaf, while the rest of the plant parts showed linear model. In conclusion densities played big role in determining the amount of carbon that can be sequestered in plant parts of rubber tree, where 500 plants/ha density shall give the highest amount of total carbon sequestration. Rubber plantation in indeed an excellent option to reduce the pressure of carbon dioxide effects to the environment by locking the atmospheric carbon into biomass form.
