R. Moral et al., EFFECTS OF CADMIUM ON NUTRIENT DISTRIBUTION, YIELD, AND GROWTH OF TOMATO GROWN IN SOILLESS CULTURE, Journal of plant nutrition, 17(6), 1994, pp. 953-962
The effect of cadmium (Cd) on nitrogen (N), phosphorus (P), potassium
(K), calcium (Ca), magnesium (Mg), sodium (Na) and the micronutrients
iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), and boron (B) on to
mato plants was studied. Two Cd treatments were imposed by adding 10 o
r 30 mg/L Cd to the culture solution as cadmium chloride (CdCl2). The
nutrients mainly affected by these Cd treatments were P, K, Fe, Mn, an
d Zn in the roots and stems and also P and Mn in fruits. Their absorpt
ion and/or translocation could be impeded by Cd. Yield was also dimini
shed but not the mean fresh weight of fruit. Plant growth was affected
negatively by Cd, root and stem length and fresh weight decreasing wi
th each increment of Cd added to the nutrient solution.
