GA3 application on tomato

What is it about?

The study was conducted to determine the influence of gibberellic acid (GA3) on the growth, fruit yield, and quality of an indeterminate tomato. Results show that the plant height of tomatoes applied with GA3 significantly increased the heights than without GA3 application. The flower count of GA3-treated tomato plants decreased. Moreover, applying GA3 at 50 ppm produced a higher percent fruit set, fruit count per plant, and fruit yield per plant, plot, and hectare than a higher concentration. However, those attributes exhibited similarities with tomato plants without GA3. Application of GA3-induced seedlessness in tomato fruits. Higher than 50 ppm concentration of GA3 displayed a lower seed count per fruit than 50 ppm and without application. The lowest seed count per fruit was observed by applying 200 ppm. Total soluble solids were higher in tomato fruits applied with GA3 than without application. The fruit yield per plant was contributed by inflorescence count per plant, flower count per plant, and percent fruit set, as indicated by their positive correlations. Applying GA3 at 50 ppm would have a higher yield with lesser seed count per fruit than the other concentrations. Although the yield of tomato plants with 50 ppm and without application of GA3 was similar, numerically, the seed count of the former was lesser than the latter. A lesser seed count per fruit would have more flesh.
