Abstract:

Present study was investigated to elucidate the role of antioxidative enzymes in imarting resistance to sucking pest attack. Antioxidative enzymes viz. SOD, CAT, POX, GR and APX were estimated in the leaves (2nd leaf & 6th leaf) of cotton genotypes infected by sucking pests at 50, 60 and 68 days after sowing (DAS) stage. The antioxidative enzyme activity before infection was maximum in 2nd & 6th leaves of G. arboreum genotypes followed by G. hirsutum resistant genotypes and minimum in G. hirsutum susceptible genotypes. After infection, antioxidative enzyme activity increased in all the genotypes in both the leaves. The maximum increase in activities of enzymes viz. catalase (CAT), peroxidase (POX), superoxide dismutase (SOD), ascorbate peroxidase (APX) and glutathione peroxidase (GR) were observed in 6th leaves after pests infection. Maximum increase in antioxidative enzymes was observed in HD418 of G. arboreum, H1098 of G. hirsutum (R) and H1454 genotype of G. hirsutum (S). The results suggested that antioxidative enzymes play an important role in providing resistance to sucking pests infection in cotton genotypes.
