  • To obtain the basic information for the use of bamboo, the anatomical characteristics of moso bamboo shoots, and 20-day-old, 60-day-old, one-year-old, and two-year-old moso bamboo were observed by using polarizing microscope. The cross section showed that the bamboo shoots consists of the early stage of cell formation, atactostele, parenchyma, and bundle sheath was formed in 20-day-old moso bamboo, and all cells completely formed in 60-day-old moso bamboo. The tissues in one-year-old moso bamboo appeared to be completely matured. On the tangential surface, no atactostele was observed in the bamboo shoot, but metaxylem, parenchyma, and bundle sheath were found. atactostele and parenchyma appeared to be formed between 20 and 60 days. All tissues and cells were totally formed and the cell wall of parenchyma were completely matured after one year. The metaxylem in bamboo shoots was observed to have pits, which means that it could be the tissues first formed of all bamboo cells.

  • The bamboo fibers from three Korean bamboo species, Moso, Henon and Timber bamboo, were prepared by disintegration after thermal treatment. The samples were prepared according to the age of growth; bamboo shoots, 20 days and 50 days of growth. The fiber quality was also investigated by morphological and chemical analyses. There was no big difference in the dry mass of fibers among the three bamboo species. However, the dry mass of fibers from 50 days of growth was increased by 34%, whereas it was ranged in 9-20% in the case of fibers from bamboo shoots and 20 days of growth. In the results of morphological analysis, the fibers could be classified as the fibers from metaxylem, the fibers from parenchyma and the fines produced during disintegration. The fibers from 50 days of growth were separated from metaxylem, whereas the fibers from bamboo shoots and 20 days of growth were mainly consisted of fibers from metaxylem and parenchyma. The chemical analysis of fibers showed that the contents of carbohydrates, lignin and extractives were not much affected by thermal treatment.
