Indole-acyl esters improve the effect of nitrogen and phosphorous fertilization by mitigating the phytotoxicity and concentrations of cadmium and lead in Jatropha curcas L. in contaminated soils

摘要

Paper description:Indole-acyl esters (ID), nitrogen (N) or phosphorous (P) fertilizers can mitigate the toxic effects of Cd and Pb on plant growth.The Box-Behnken three-variable partial factorial design was utilized to study the interaction effects of three factors on Jatropha curcas L growth. The combined effects of two or three factors on plant growth were studied using single factor experiments.Combined ID, N, and P treatments increased the ability of Jatropha curcas to grow on heavy metal-contaminated soils.This paper proposes a novel methodology that is related to the interaction effects of multiple factors on plants.
