Abstract

A study were carried out to investigate the effect of gibberellic acid (GA₃) and blossom removal on fruit quality of strawberry cv. belrubi under subtropical region. Various quality parameters were monitored with the application of three concentrations of gibberellic acid (GA₃) 50 ppm, 100 ppm and 150 ppm and two levels of blossom removal partial and without deblossoming. Results of experimental showed that the highest juice content of fruits (86.70/86.46%), TSS (7.56/7.43°Brix), sugar content (4.33/4.26%), pH of fruit (3.87/3.86) were recorded in lower concentration of gibberellic acid 50 ppm treated plants with partial deblossoming during both the years of experimentations (2003–04 and 2004–05). However, the highest vitamin-C (63.75/63.66 mg/100g) was obtained with treatment combination 100 ppm GA₃ with partial deblossoming. In addition, the highest acidity of fruit (0.77 and 0.79%) was registered in control (water spray without deblossoming) during both the years. From this study, it can be concluded that spraying of 50 ppm GA₃ with partial blossom removal treated plants showed improve of fruit quality.
