Description
Summary: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 O2- 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.
