“…In general, tree height and DBH have a positive correlation with the biomass of each organ, such as the stems, branches, and leaves of the tree (Kwon and Lee 2006). Therefore, the standing biomass of the aboveground Q. glauca forest was estimated by substituting DBH for the allometric equation suitable for each species (Table 1) (Jeong et al 2014;Kwak et al 2004;Mun 2006;Rodin and Bazilevich 1967;Son et al 2014). And when there is no allometric equation relative to a specific tree species, we applied suitable equation considered classification group, height and shape type.…”

Background: To assess the carbon sequestration capacity and net ecosystem productivity (NEP) of Quercus glauca forests, we analyzed the net primary productivity (NPP), carbon storage, and carbon emission of soil in a Q. glauca forest on Jeju Island (South Korea) from 2016 to 2018. Results: The average carbon stock in the above-and below-ground plant biomass was 223.7 Mg C ha -1 , while the average amount of organic carbon fixed by photosynthesis was 9.8 Mg C ha -1 yr -1 , and the average NPP was 9.6 Mg C ha -1 yr -1 . Stems and branches contributed to the majority of the above-and below-ground standing biomass and NPP. The average heterotrophic carbon emission from the soil was 8.7 Mg C ha -1 yr -1 , while the average NEP was 1.1 Mg C ha -1 yr -1 . Although the carbon stock, carbon absorption, and soil respiration values were higher than those reported in other oak forests in the world, the NEP was similar or lower. Conclusions: These results indicator that Q. glauca forests perform the role of a large carbon sink through the CO 2 absorption in the plants in terms of carbon balance. And it is judged to be helpful as data for assessment of carbon storage and flux in the forests and mitigation of elevated CO 2 in the atmosphere.

“…To screen candidate stands and select base populations of Q. salicina and Q. glauca, some relevant literatures had been searched [3,[18][19][20][21][22]. However, there were limitations in understanding of population size, density and growth performance of target species, which were needed for the selection of base populations.…”

This study was conducted to select plus trees of two evergreen oaks, Quercus salicina and Q. glauca, in Korea. Evergreen oaks are distributed in subtropical region in Korea and have recently emerged as one of the alternative tree species against climate change. Accordingly, a tree breeding program is underway to foster evergreen oaks as a reforestation species for the future. Through intensive survey on the distribution range, 15 stands (8 for Q. salicina, 3 for Q. glauca, and 4 for both species) were selected as base populations. To select candidate trees, we developed a subjective grading system with six characteristics in three categories and introduced a weighted generalized value (GVIw) to compare superiority of candidate trees. The candidate trees were screened using baseline value ‘0’, i.e., if GVIw > 0, then accepted and if GVIw < 0, then rejected. After then, adjustment was conducted to avoid biasing the selection of plus trees for a particular location. Through this process, 44 candidate trees in Q. salicina and 41 candidate trees in Q. glauca were selected as plus trees. Finally, the results and implications were discussed in relation to evergreen oak breeding in Korea.
