using simulation, found that applying genetic selection
on growth could substantially enhance C sequestration. This
study compared provenances in biomass and C credits using
empirical data. Results suggest that planting fast-growing provenances
should result in benefits in biomass productivity and C
sequestration indirectly. The benefits in C stock will be larger if
provenance selection is made based on DBH or volume, rather than
on H. This makes sense as DBH usually has a larger weight on
determining tree volume, the most important component of C
stock. Furthermore, seed sources with a relatively larger DBH
growth tend to partition more C belowground. Thus, in the future,
genetic selection programs for spruce species should focus more on
DBH or volume growth.
