Abscission of reproductive parts was studied in tomato (PKM 1).The plants were sprayed with ATONIK (nitrophenols) on floweringand fruit set stage at four different concentrations. Observationswere recorded in the flowers and developing fruits. Application ofATONIK increased the superoxide dismutase (SOD), catalase (CAT),peroxidase (POX) and auxin content coupled with decreasedpolyphenol oxidase (PPO) LAA oxidase (LAAO) enzyme activity overcontrol significantly. Among the concentrations tried, application ofATONIK at 0.4% (v/v) during fruit set stage was found to besuperior in recording higher antioxidant enzymes activity and auxinlevel which had reflected in increased number of flower clusters perplant, number of fruit clusters per plant, fertility co-efficient andyield of tomato.
