Abstract


KWON, Oh Yong (Dept. of Botany, S. N. U.) Studies on the identification of Pleioblastus Simoni in Korean Bamboos. Kor. Jour. Bot. V(3): 5-10, 1962
Studies on the anatomical observation of Bamboos distributed in East-South Asia for systematic botany were sccrecely reported except for the morphological studies on Bamboos, which was investigated by Dr. Hiroshi Usui.^(3)4)) present author^(5)) and others. Recently it has been certain that it could be hardly classify some species of bamboo family without this work.
For this reason the author reported the anatomical studies on Korean bamboos in 1959. and furthermore the author intended to identify the two species of Pletoblastus Simoni Nakai in Korean bamboos by studying the characteristics of internal structure and qualitative assay of free amino acid containg in Pleioblastus Simoni Nakai (1), (2).
In view of fact that there is some diferences between two species, it is likely to be identifiable completely different species one another. Futhermore, a lot of characteristics surveyed by the author were as follow: It was reassumed that two species cultivated under same conditions for three years were different alternately in the species of Pleiblastus Simoni Nakai. At the same time, these studiecs could clarify some evolutional processes of bamboo familly. On the other hand, it was found that two species had not only the obvious difference in aerenchyma, the size of thitkwallecd parenchyma and bulliform cell, but also the internode of Pleloblastus Simoni Nakai(1) is longer than the other, the speed of growing is more rapid, the leaf of former is narrow and that of latter is wide. The free amino acids containg in each species were found as 18 kinds, especially Pleiobkastu ilmonl Nakai (2) had not Histidine in spite of containg in Pleioblastus Simoni Nakai (1).
From the characteristics and the experiments described above, it seemed to the author that Pleiblasus Simoni Nakai(2), which was growing at the region of Pohang in Korea, was a variety of Pleioblastus Simoni Nakai (1) which was growing at the region of Ulsan in Korea.
