Abstract

The metabolic responses in the organs of 42-day-old Amaranthus caudatus L. plants to the effect of 90 μM Cd and 300 μM Zn in water culture were studied using GC-MS method. It was shown that metabolic response in amaranth leaves depends on the leaf age. The key metabolites in the response to Cd and Zn in the roots and young leaves were sugars, and in the mature leaves organic acids - oxalate and malate, which indicates their functional role in the mechanisms of amaranth tolerance to the stress effect of Cd and Zn.
