and their coleoptiles and primary leaves were sprayed with the same c<strong>on</strong>centrati<strong>on</strong> SA<br />

soluti<strong>on</strong> or with water in the case of c<strong>on</strong>trol lot. The value for the c<strong>on</strong>trol lot was<br />

c<strong>on</strong>sidered 100%.<br />

CONCLUSION<br />

The exogenous 0.01 mM, 0.1 mM and 1.0 mM SA soluti<strong>on</strong>s treatments significantly<br />

increased the assimilatory pigments c<strong>on</strong>tents in leaves of wheat plantlets (Triticum<br />

aestivum) when the leaves and the coleoptiles was sprayed with this soluti<strong>on</strong>, in<br />

comparis<strong>on</strong> with the same parameters measured in leaves of wheat plantlets of the<br />

c<strong>on</strong>trol lot treated with water. The 0.1mM SA soluti<strong>on</strong> produced the highest increased<br />

(with 40% from the c<strong>on</strong>trol lot for chlorophyll a, with 36% from the c<strong>on</strong>trol lot for<br />

chlorophyll b and with 50% from the c<strong>on</strong>trol lot for carotenoid pigments).<br />

Salicylic acid, in the used c<strong>on</strong>centrati<strong>on</strong>, activated the synthesis of carotenoids,<br />

xanthophylls and the level of clorophyll pigments, in primary leaves of wheat plantlets.<br />
