Tea plant has been mllainly grown in shade aild wet flace of several temple surroundings for a long years in sourthern area of Korea, since it has been introduced about1,000 years ago In those rlaces, it has been mostly grown in semi-wild, but recentlycultivated in a part of Bosung-gun, Cheonnanl province. External forms of tea plantwere considered that those have a little changed according to geographic andclimatic conditions of growing places. To investigate how is the variation of teaplant by the difference of environment conditions under growing places, we had ex-amined the protein and isozyme patterns of seeds of tea plant. In spite of difference ofgeographic and climatic conditions, the patterns of catalase, esterase, acid phosphat-ase isozyme and protein showed the same aspects.
