Abstract

A field experiment was conducted at Horticultural Research Station, Odisha University of Agriculture and Technology, Bhubaneswar during 2020-2022. The experiment was carried out with ten treatments involving different concentrations of plant growth regulators viz., Brassinolide (0.5 ppm and 1.5 ppm), Salicylic acid (150 ppm and 300 ppm), NAA (150 ppm), and their combinations were embedded in Randomized Block Design with three replications. Effect of plant growth regulators has significant effect on physio-chemical properties of sapota in relation to Total Soluble Solid, titratable acidity, reducing sugar, total sugars and ascorbic content of fruits. Among all Brassinolide alone 1.5 ppm and in combination with NAA 150 ppm has visible effect in increasing physio-chemical properties of sapota fruit.

Sapota, Physio-chemical, NAA, SA, Brassinolide

Conclusion

Application of plant growth regulators has significantly promoted the physio-chemical properties of sapota in relation to total soluble solid (TSS), Acidity, Total sugars, reducing sugars and ascorbic content of fruits. Brassinolide alone 1.5 ppm and in combination with NAA 150 ppm has visible effect in increasing physio-chemical properties of sapota fruit. As the application of brassinolide stimulate the source sink relationship via improving the mobilization and accumulation pf assimilates to the growing fruits, which ultimately improves the physiochemical properties of fruits.
