Influence of plant bioregulators on growth, yield and physico-chemical characteristics of strawberry

Abstract

The present investigation was carried out to study the influence of plant bioregulators on growth, yield and quality of strawberry cv. Festival. The study indicates that growth, yield attributing characters, yield and quality of strawberry fruits were significantly influenced by various bioregulators. Among different plant bioregulators, GA3 150 ppm recorded the significantly the highest yield of 116.18 q ha-1. It also recorded the highest value with respect to different growth parameters, viz. plant height (22.27 cm), spread (26.35 cm), number of runners (9.27) and flowering and fruiting duration (83.02 days). Among different yield attributing characters like berry set (87.93%), berry length (46.74 mm), berry diameter (29.75 mm), berry weight (18.62 g), berries plant-1 (32.37), GA3 150 ppm showed superiority than other plant bioregulators. Regarding various physico-chemical parameters, viz. TSS, acidity, total, reducing and non-reducing sugars of fruits, ethrel 250 ppm exhibited significantly the maximum values. The treatment GA3 150 ppm was the best plant bio-regulator treatment for improving growth, and yield. However, with respect to physico-chemical characteristics of fruits, ethrel 250 ppm was found best.
