Table 1 Information of intra-annual density fluctuation (IADF) formation in micro-cored trees. The number of xylem cells before (cnb) and after (cna) IADF formation, corresponding ring width before (rwb) and after (rwa) IADF formation and their total (rwt) were presented; BstIADF indicates the extra stem biomass when IADF formation; % increase means percent increase in stem biomass when IADF formation (%)
