PROBLEM TO BE SOLVED: To produce "various types of bamboos from upright to bend with a height and internode usable indoors", which have a high commercial value as a garden tree or an art object and a wide range of use and which has been difficult to produce by conventional technique.SOLUTION: By peeling or cutting off a culm sheath to expose the culm to a light and to inhibit the growth of the culm, intervals become shorten and at the same time the culm becomes easy to bend, and therefore a shape of interest is enabled to be obtained by pulling with a string. As a result, various types of bamboos with short internodes from upright to bend can be produced.SELECTED DRAWING: Figure 3
