Water culture technique was used to study the role played by CdCI2, NaF and 2,4-DNP when supplied in various levels on photosynthetic pigments, carbohydrate and nitrogen content in maize, sunflower and broad bean plants. The piphasic action of the test inhibitors involving stimulation of pigments biosynthesis at low concentrations and inhibition at higher concentrations was exhibited in case of maize and bean plants, while in case of sunflower this biphasic action was demonstrated only under the effect of 2,4-DNP. Accumulation of total carbohydrates and total nitrogen was substantially affected by the inhibitor supply. There was some evidence to indicate the presence of certain effective levels of the applied inhibitors manifesting depressive or promotive effects on the accumulation of the total carbohydrates and total nitrogen in the different organs of the treated plants.

Keywords: CdCI2, NaF, 2, 4-DNP, Pigment content, Carbohydrate, Zea mays, Helianthus annuus, Vicia faba.
