ABSTRACT
In this paper we studied the influence of exogenous 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 wheat caryopsis - by pre-soaking it for 6 hour before germination -on some physiological and biochemical processes including: plant growth and development of plants, total absorption capacity of roots, peroxidase activity in wheat seedling roots, and assimilatory pigments content of the first leaves of wheat seedlings, in comparison with the same parameters of the control lots which were treated with tape water. The results showed that exogenous 0.01mM ASA solutions, administrated to the wheat caryopsis significantly increased the length of the roots and coleoptiles of wheat seedlings, and the total absorption capacity of roots. The 5.0 mM ASA solution determined a 100% inhibition of the germination; 0.1 mM and 0.5 mM ASA solution significantly increased the total chlorophyllian and carotenoid pigments content, and more concentrated solutions significantly decreased this parameter.
