The experiment was done according to complete randomized block design with three replications in Al-Kefel area.

The results were summarized as follow: All acids treatments led to increase chlorophyll content compared to water treatment.

Salicylic , 1mM and GA3, 100 mg/l were superior and caused an increase of 18.3 and 17.9 % respectively as compared to water treatment.

Foliar, soaking + foliar treatments caused an increase in leaf chlorophyll content as compared to soaking only.

The interaction between acids and methods of treatment had a significant effect also.

Salicylic acid at 1 mM caused a significant effect on proline as compared to all other treatments, and caused 17% increases as compared to water treatment.

GA3 at 100 mg/l caused a significant effect also on proline as compared to control with 7.7 % increases.

Soaking + foliar treatment led to increase proline significantly as compared to soaking only.

The interaction between acids and methods of treatment had a significant effect also.
