Abstract

The study examined the effects of kinetin (KIN) and indoleacetic acid (IAA) applied as seed treatment of salinity stressed. Plants were grown in pots containing peat and perlite in 1:1 (v/v) mixture. Different treatments including (1) control (nutrient solution alone), (2) salt stress [100mM sodium chloride (NaCl)], (3) 100mM NaCl and 1mM kinetin (KIN), (4) 100mM NaCl and 2mM KIN, (5) 100mM NaCl and 1mM indole acetic acid (IAA), (6) 100 mM NaCl and 2 mM IAA, (7) 100mM NaCl and 25mg L−1 KIN and (8) 100mM NaCl and 25mg L−1 IAA were designed. The seeds were soaked in KIN or IAA solution for 12h. Salt stress reduced the total dry matter, seedlings length and relative water content (RWC), but increased activities of APX and CAT. However, seed treatments with KIN or IAA did not improve salinity tolerance in wheat and maize plants. Furthermore, seed treatments with KIN and IAA reduced the activities of antioxidant enzymes in the salt stressed-plants.
