An hydroponic experiment was conducted to study the effects of chromiu
m (Cr3+) on the distribution of nitrogen (N), phosphorus (P), potassiu
m (K), sodium (Na), calcium (Ca), magnesium (Mg), and Cr in the plant,
and the growth and yield of a tomato plant. Three Cr treatments were
established (0, 50, and 100 mg Cr/L in a nutrient solution). In genera
l, the nutrient element concentration in stems and branches was signif
icantly affected by the Cr treatments. Chromium accumulated preferenti
ally in the roots and low transport was detected to the aerial parts.
Growth was diminished due to Cr presence in the nutrient solution. Tot
al yield was not affected, however the number of fruits was diminished
and the mean fresh weight of fruit increased with each increment of C
r in the nutrient solution. Chromium was not detected in the edible pa
rt (fruit) of the plant.
