Summary The influence of (2-chloroethyl)trimethylammoniumchloride on growth and cell metabolism of Triticum aestivum var. Kolibri was investigated. CCC was added to the nutrient solution on the 11th day of development with a final concentration of 10 −2 mol·1 −1 . It immediately stopped root growth and showed a strong inhibitory influence on the growth of the leaves. Smaller and fewer cells accounted for the reduction in final leaf size of about 40 %. The content of soluble proteins and soluble reducing sugars were significantly increased in the treated leaves. CCC also exhibited a stimulating effect on the synthesis of RubPc-ase protein and the in vitro activity of this enzyme. In contrast to this, the dry weight remained unchanged and the maximum CO 2 -fixation was even decreased. This result is briefly discussed in connection with a possible involvement of water stress induced by CCC.
