บทคัดย่อ (EN): Growths and carbon stocks in a series of para rubber plantations on Chakkarat soil series in northeastern Thailand were investigated including 1, 5, 10, 15 and 20 years old, and a natural forest. Totally 15, 40 x 40 m sampling plots were used for studying rubber growths, three plots per each aged class plantation and one plot for the natural forest. In each plot, stem girth at 1.3 m above ground, crown width and height of trees were measured. One rubber tree having the mean growth in each aged class plantation was cut and separated to stem, branch, leaf and root biomass for making allometry equations. Fifteen soil pits were made in each plot, and soil samples were collected along soil profile. Soil physical and chemical properties were analyzed in laboratory. Rubber tree densities varied between 80-109 trees/rai (1 ha = 6.25 rai). Stem girth and height growths were increased with the plantation ages. The growths were very rapid for rubber trees having ages between 1 and 15 years old and become slow for the older trees. The biomass amounts of 1, 5, 10, 15 and 20 years old plantations were in the order of 21.25, 55.24, 102.39, 140.50 and 215.39 Mg/ha. Ecosystem carbon stocks in these plantations were increased with tree ages as 26.29, 48.28, 76.62, 95.83 and 135.38 Mg/ha, respectively. They involved two compartments; (1) biomass carbon: 12.03, 31.45, 58.10, 79.78 and 122.01 Mg/ha; and (2) soil carbon: 14.26, 16.83, 18.52, 16.05 and 13.37 Mg/ha. The total carbon storage in natural forest was 134.62 Mg/ha; 124.20 Mg/ha in biomass and 10.42 Mg/ha in soil. The young plantations had the high carbon percentages in soil and low in biomass whereas carbon allocation in the older plantations was higher in biomass and lower in soil system.
