The shoot fresh mass, root length and numbers of two potato (Solanum tuberosum L.) cultivars Favorita Helanwuhua were increased significantly by the application 0.2 - 2 mg dm-3 jasmonic acid (JA) in Murashige Skoog medium. However, growth explants was inhibited JA at high concentrations (20 50 dm-3). Chlorophyll content explant leaves decreased with an increase concentration JA. In treated peroxidase activity increased, while more than decreased. Under dark, microtuber numbers, mass percentage big microtubers not promoted
