Influence of Gibberellic Acid and Blossom Removal on Fruit Quality of Strawberry (Fragaria x ananassaDuch.) CV. Belrubi

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.
