Effect of Salicylic acid in salt stress on some quantitative, qualitative and growth in Parsley (Petroselinum hortense Hoffm.)

To study the effect of salicylic acid in control Nacl salinity stress factorial experiment in a completely randomized design with 9 treatments included two levels of 50 and100 mg of sodium chloride also Salicylic acid on two levels 1 and2 mM and as well as their interactions in 3 replications were conducted. Parsley seeds after planting it in context, about 3 weeks for germination needs. Then in the fifth week after planting, irrigation the soil with sodium chloride solution was conducted for one week every two days. Salicylic acid spraing(200 ml per pot) was conducted one week every two days. No watering pot with sodium chloride and sprayed with salicylic acid were used as controls. Quantitative and qualitative traits such as plant fresh weight and dry weight of shoot and root, total chlorophyll content, proline and superoxide dismutase activity was evaluated. The results showed that the treatment of Salicylic acid 2 mM had the greatest effect on salinity control and result at 1% statistical level had significant effect.
