Abstract
Salt stress is one of the most critical factors hindering the growth and development of plants Paclobutrazol PBZ is widely used to minimize this problem in agriculture because it can induce salt stress tolerance in plants This study investigated the effects of PBZ on salt tolerance of seedlings from two Chinese bayberry cultivars ie Wangdao and Shenhong Plants were treated with three salt concentrations 0 02 and 04 NaCl and two PBZ concentrations 0 and 20 μmol L–1 Application of PBZ increased a relative water content proline content chlorophyll a+b content and antioxidant enzyme activities in both cultivars resulting in a better acclimation to salt stress and an increase in dry matter production We concluded that PBZ ameliorated the negative effects of salt stress in Chinese bayberry seedlings
