الملخص EN

The present study was performed at the Agriculture and Marshes College / University of Thi-Qar during one year from Oct-2017 to Oct- 2018 for studying the effect of sodium chloride and salicylic acid and their interaction in some chemical properties of date palm leaves.

Phenix dactylifera L.

Nabout Saif C.V resulting of tissue culture.

The study was carried out as a factorial experiment according to the randomized complete block design (RCBD) using four concentrations of NaCl (0, 75, 150 and 225 mM) and three concentrations of salicylic acid (0, 50 and 100 mg.L-1) for three replications.

The results demonstrated that, NaCl at 75 mM significantly increased the total dissolved carbohydrate concentrations and showed the highest mean value when compared to the control group that showed the lowest mean value.

The NaCl at 225 mM significantly increased the level of Peroxides activity compared to the control group that showed the lowest mean value and with no significant differences compared to NaCl at (75 mM and 150 mM).

In addition, NaCl at 225 mM 150 mM significantly increased the level of catalase enzyme compared to the control group that showed the lowest mean value.

Salicylic at 50 mg.L-1 significantly increased the total dissolved carbohydrate and with no significant difference to the control group, while the treatment of Salicylic at 100 mg.L-1 recorded the lowest mean value.

Furthermore, the interference between NaCl and salicylic acid treatments appeared to possess significant effects in which 75mM of NaCl and 50 mg.L-1 of salicylic acid led to increase the total dissolved carbohydrate level.
