3.1 | Comparison of carbon sequestration among families
The height, DBH and carbon sequestration data for individuals are shown in Table 1 and Table S2. Family No. 38 had the greatest mean tree height at 14.15 m; this was 1.22 times the lowest mean height (11.54 m), which was observed in family No. 21. family No. 66 had the largest mean DBH (12.20 cm); this was 1.16 times the lowest mean DBH, which was observed in family No. 4 (10.49 cm). family No. 66 had the highest mean carbon sequestration value at 28.245 kg; this was 1.45 times the lowest mean carbon sequestration, which was observed in family No. 4 (19.501 kg). Duncan’s multiple comparison results showed that there were significant differences in tree height, DBH and carbon sequestration among the different families. By considering the data from all the three indicators, families No. 4, No. 64 and No. 66 were selected as the representative families showing low, medium and high carbon sequestration for the subsequent experiments.
