Effect of salinity and soil zinc application on biochemical indices and some growth parameters of pistachio

摘要

Pistachio plants (pistasia. vera L.) were grown in potted soils exposed to four salinity levels (0, 1000, 2000, 3000mg·kg<'-1> soil as NaCl) and three zinc (Zn) levels (0, 5, 10mg·kg<'-1> soil as ZnSo<,4>. 7H<,2>O). As the salinity levels increased, the leaf proline content significantly increased. However, Zn application declined the proline content. Growth parameters such as leaf, stem, and root dry weights significantly decreased with increasing salinity levels, whereas increased with Zn application in saline medium. However Zn application had no significant effects on these growth parameters.
