تأثير حامض الساليسيلك في نمو الأصل سوينكل ستروميلو النامي في ظروف الإجهاد الملحي خارج الجسم الحي

الملخص EN

The research aimed to study the include amidst nutritional Salicylic acid in the growth of plantlets in citrus root stock under salty stress in vitro.The research was implemented as an experiment in complete random design(CRD)with two factors, Sodium chloride and Salicylic acid concentrations.

branches multiplier resulting from the first phase were planted in MS has doubled branches which supplement (2 mg.l-1 BA+0.25 mg.l-1 IBA) with addition of Sodium chloride (0.0,0.2,0.4,0.6,0.8,1)% and Salicylic acid concentrations(0,1,2,4) mg.l-1 for six weeks .

Then was measured average number of branches consisting , length , number of leaves, fresh and dry weight of shoots and content of proline as indicators of response to salinity tolerance.

The results showed a significant effect of the negative qualities of salt Sodium chloride in the growth in plantations tissue with increase the salt concentration in the doubled branches amidst.

It happened significant reduction in the number of branches and the length , number of leaves as well as the content of proline when increase the salt concentration in the amidst of doubling from 0.0% up to 1% .

As it turns a discrepancy in the root stock response to the stress caused by the presence of salt in the amidst nutritional of doubling the presence of Salicylic acid.

it superiority concentrations of Salicylic acid 1mg.l-1 significantly on the rest of concentrations in most of the traits under consideration except focus 4mg.l-1 in qualities number of branches and number of leaves then followed by focus 2mg.l-1 for most traits.

t also shows results of overlap concentration 1 mg.l-1 of salicylic acid superiority of with a concentration 0.0% sodium chloride for each of the qualities lengths of branches, number of leaves and fresh and dry weight of branches .

While focus superiority of 4mg.l-1 of Salicylic acid with an emphasis 0.0% in the number of branches, As focus and the superiority of 4 mg.l-1 with the salt level of 0.4% to give a higher concentration of proline in the branches.
