Abstract:	In this paper we studied the influence of exogenous Salicylic Acid (SA) and Acetylsalicylic Acid (ASA) solutions, administrated in different concentrations (0.01 mM, 0.1 mM, 0.5 mM, 1.0 mM and 5.0 mM) to the sunflower seeds on the growth of the embrionary roots and on the total absorption capacity of the roots, in comparison with these parameters registered in the control lot, which was germinated in tap water. The results showed that, in comparison to the control lot germinated in tape water, the exogenous 0.01mM, 0.1mM and 0.5 mM SA or ASA solutions administrated to the sunflower seeds, increased the length of the seedling roots, the 1.0 mM SA or ASA solutions significantly decreased this parameter, and the 5.0 mM SA or ASA solution inhibited the germination of sunflower seeds.The total absorption capacity of sunflower roots was determined by the uptake in the roots of a neutral red solution (a vital stain). The results showed that, in comparison with the same parameters determined on the control lot germinated on a filter paper moistened with tap water, this absorption was significantly modified when the sunflower seeds were germinated on a filter paper moistened in SA or ASA solution.
