Abstract: To determine the effects of linolenic acid (LA) on growth and general chemical components of tobacco‘K326’, the activities of POD and SOD in leaves, agronomic traits and general chemical components of tobacco treated with LA in Xuchang and Zunyi were analyzed. Results showed that, SOD activities and proline contents were raised in tobacco leaves after 10 mmol/L LA treatment. Plant height and leaf number were also increased. Leaf number was increased by 1.91 in Xuchang and by 2.85 in Zunyi, respectively. The sugar alkali ratio tended to be 10, thus to harmonize the inner chemical components
