Abstract
Barley plants (Hordeum vulgare L. cv. Obzor) were grown as a water cul ture in a climatic room. One part of them was subjected to a long-term Cd2+ stress -12 d with 5.4x10(-5) M Cd. The Cd2+ stress inhibited for mation of the photosynthetic apparatus and its capacity for C-14 photo assimilation, decreased the content of soluble proteins, increased the dark respiration rate and the free amino acids content, disturbed pla nt water relations, as well as the distribution of C-14 within primary photoproducts of the treated barley plants.
