Abstract

Different levels of calcium for water culture peanuts were designed to research the influence of calcium on the peanut of Quanhua 10 growth and development and on the defence system of active oxygen in leaves. Under high calcium level stress, stem was stronger, leaves were thicker and bigger, pods were much more and bigger and filled, Chl content, catalase (CAT) activity and peroxidase (POD) activity were more higher, malondialdehyde (MDA) content, O_(2~~~~~~(·)) generative rate and electrical conductivity were lower. The influence of low calcium on peanuts growth and development was closely related to the damage of active oxygen defence system in plants.
