Enzyme Levels in Pea Seedlings Grown on Highly Salinized Media
Year: 1970
Type: article
Abstract: The levels of 18 enzymes were determined in leaves, stems, and roots of 11-day-old pea seedlings grown in a liquid medium or in the same medium containing, in addition, 5 atmospheres of either NaCl, KCl, Na(2)SO(4), or K(2)SO(4). Though the plants grown in saline media were stunted, the specific activities of the enzymes were the same in the given tissues of all plants. Also, the electrophoretic pattern of isozymes of malate dehydrogenase was not altered by growth of the plants in a saline medium. However, the isozyme pattern of peroxidase from roots of salt-grown plants was altered in that two of the five detectable isozymes migrated a little more slowly than those in extracts from nonsaline plant tissues.
