The culm color patterns in moso bamboo (Phyllostachys edulis)

Generally, moso bamboo (Phyllostachys edulis) has three types of color patterns at the internodes of clums. P. edulis f. luteosulcata (YM) has green slot & yellow wall at internode, but P. edulis f. viridisulcata (GM) have an adverse phenotype with green wall & yellow slot. The protype of moso bamboo (P. edulis f. pubescens; MB) has green intenodes. To figure out the generation of culms with different color patterns, intercalary meristems of tender internodes were collected at the early stage with inconspicuous colors and at the late stage with distinct colors from the three types of moso bamboo.
