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 peroxidaseas enzymes implied in the removal of H 2 O 2 , of O 2radical and of ion HOthat have devastating effects on the vegetable cell, on the Krebs cycle's dehydrogenasesas main way to produce energy, respectively of the chlorophyll a, b and carotenesas photoassimilatory pigments, but also as biologic antioxidants.
