2.2 Clonal configuration analysis
Then the leaves of all the sampled individuals were cut off with
scissors, dried using a color-changing silica gel, and stored at -80℃ in
a laboratory refrigerator. Each sample was transferred to the
laboratory, where the rhizome nodes (Fig. 1) were observed and measured,
once the soil was removed from the roots. The number of C.
udensis rhizome nodes could be added during each growing season per
year. The number of buds (active and dormant buds) on each rhizome were
counted. The ages and numbers of branches of the rhizome were also
counted.
One-way ANOVA (analysis of variance) of all obtained data was analyzed
using SPSS 20 software, and LSD (least-significant difference) was
employed to compare the paired data for significance.
