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.
