Heavy Metals and 2,4-Dinitrophenol Impact on Some Physiological and Biochemical Parameters in Capsicum Species

Abstract

The accumulation of heavy metals and of pesticides in the soil have a negative impact on Capsicum chinense var. Aji Mochero and Capsicum baccatum var. pendulum Bishop's Crown species, the present work highlighting the exerted influence on the superoxid-dismutase activity, catalase and peroxidase - as enzymes implied in the removal of H₂O₂, of O^2- radical and of ion HO^- that have devastating effects on the vegetable cell, on the Krebs cycle’s dehydrogenases - as main way to produce energy, respectively of the chlorophyll a, b and carotenes - as photoassimilatory pigments, but also as biologic antioxidants.
