Abstract
The structure and ultrastructure of the second leaves of 10-d-old barley pl ants (Hordeum vulgare L. cv. Alfa) was investigated after long-term treatme nt with salicylic acid (SA) in concentrations of 0.1, 0.5 and 1.0 mM. The t reatment induced: 1) suppressed bulliform cells formation in the adaxial ep idermis (1.0 mM SA); 2) reduction of apoplast in the mesophyll (0.5 and 1.0 mM SA); 3) formation of invaginations (0.1 and 0.5 mM SA) and proliferatio ns (0.5 mM SA); and 4) thylakoid destruction and coagulation of the stroma (1.0 mM SA).
