Catalase, peroxidase, and chlorphyll relationships to yield and iron deficiency chlorosis in Cicer genotypes

Abstract

The extent of Fe deficiency chlorosis varied widely among genotypes of Cicer arietinum. Chlorophyll concentration of leaves and grain yields decreased in unsprayed genotypes with increases in chlorosis, but no significant relationship between chlorophyll and grain yield was noted. However, the activities of catalase and peroxidase were correlated with grain yield. Even though all of the genotypes recovered from chlorosis after foliar applications of ferrous sulphate solutions, the activities of catalase and peroxidase were not restored in the severely chlorotic genotypes as much as were chlorophyll concentrations.

Key words:

• Metallo‐enzymes
• Chlorophyll content
• Genetic lines
• Cicer arietinum
• Chickpea
