The zymogram of acid phosphatase showed different isozyme patterns in roots, leaves, seedlings and calli. One of the medium mobility isozymes, cell-wall-containing enzyme, commonly occurred in all tissues. Some isozyme had tissue-specificity. The optimal pH of acid phosphatase was around 5. Enzyme activity was strongly inhibited by HgCl2, (NH4)4Mo7O24, NaF, CuSO4 and KH2PO4. In germinating seeds, the increasing activity of acid phosphatase related with transportation of phosphates and store food had been suggested. DO -10.6165/tai.1991.36.108
