Abstract:
Abscission of reproductive parts was studied in tomato (PKM 1). The plants were sprayed with ATONIK (nitrophenols) on flowering and fruit set stage at four different concentrations. Observations were recorded in the flowers and developing fruits. Application of ATONIK increased the superoxide dismutase (SOD), catalase (CAT), peroxidase (POX) and auxin content coupled with decreased polyphenol oxidase (PPO) IAA oxidase (IAAO) enzyme activity over control significantly. Among the concentrations tried, application of ATONIK at 0.4% (v/v) during fruit set stage was found to be superior in recording higher antioxidant enzymes activity and auxin level which had reflected in increased number of flower clusters per plant, number of fruit clusters per plant , fertility co-efficient and yield of tomato.
