The effects of 2, 4-dichlorobenzoic acid (DCLBA) on the number of cucumbers (<I>Cucumis sativus</I> L.) harvested were evaluated by split-root system hydroponic culture. DCLBA (10μmol·liter<SUP>-1</SUP>) in the nutrient solution severely damaged the roots by disrupting the integrity of epidermal cells, and remarkably inhibited the uptake of NO<SUB>3</SUB><SUP>-</SUP>, H<SUB>2</SUB>PO<SUB>4</SUB><SUP>-</SUP> and <SUP>Κ</SUP>+ ions. As a result, DCLBA significantly inhibited the number of cucumbers harvested. Supplementation of the nutrient solution with activated charcoal in one side pot recovered the inhibition especially for the uptake of nutrients, and partly recovered the harvested fruit number per plant compared to that without charcaol. These results indicated that DCLBA affected the uptake of nutrients, and inhibited the growth of young fruit after adsorption from roots.
