Abstract

Peroxidase and polyphenol oxidase activities in healthy and viral infected sunflower (Helianthus annuus L.) leaves

Author(s): S.Papaiah, G.Narasimha

Sunflower (Helianthus annuus L.), a member of compositae family is the most important edible oilseed crop. Sunflower necrosis virus is one of the viral diseases in sunflower plants, The main symptoms of this disease chlorotic mosaic, leaf necrosis, stem necrosis, leaf distortion and plant death. In this study, plant enzymes, peroxidase, and polyphenol oxidase activities were assessed and chlorophyll content was measured in healthy and sunflower necrosis virus diseased plants. The peroxidase and polyphenol oxidase activitieswere enhanced, where as chlorophyll content was decreased in viral infected leaves than in healthy sunflower plants.
