Abstract

A study was undertaken to evaluate the uptake of Mo, Se, Zn, and Cr in soil–plant systems and to investigate the effect on the yield and carotenoid composition of carrot. Despite the beneficial effects of Se and Cr to plant growth, at low concentration they were extremely phytotoxic when presented at relatively high concentration in the soils. In the case of Mo and Zn treatments, carrot plants showed good adaptation to high levels of these elements. Although Mo treatments had no phytotoxicity on the plants, the highest dose resulted in a significant decrease in the carotenoid content of the roots. Amending the soil with Se and Zn stimulated an increase of α-carotene and lutein synthesis and a decrease of β-carotene with slight increase in the total carotenoid content.
