چکیده :

Soil pollution with heavy metals can be very harmful for plants. In the meantime, lead can be a serious threat to the environment due to its low mobility and high sedimentability. One of the methods of remediation of soils contaminated with heavy metals is the use of chelating materials. The aim of this study is to evaluate the potential of two natural chelates of glutamic acid and aspartic acid in reducing lead stress in medicinal plants. Today, the use of these two chelates as growth regulators is increasing. These two amino acids act in the transfer and storage of nitrogen and directly and indirectly affect the growth and development of plants. In general, chelating materials can change the solubility and absorption capacity of heavy metals by having multiple bonding sites in their structure. In this study, the mechanism of the effects of foliar spraying of glutamic acid and aspartic acid in reducing lead stress in some medicinal plants has been investigated. In general, it can be said that the use of chelating agents, especially glutamic acid and aspartic acid, can have a positive and significant effect on reducing lead absorption by medicinal plants.
