Development of Seedless Star Fruit and its Antioxidant, Biochemical Content and Nutritional Quality by Gibberellic Acid Hormone as Genetically Modified Component

Star fruit is one of the most important fruit that meets the requirements of healthy nutrition. It is a tasty and valuable fruit crop, containing a lot of biologically active substances and significant for dietary qualities. Plant hormone keeps a significant role to enlarge the fruit size and quality development. Fruit growers have a lot of interest in making fruit enlargement and shorten maturity to harvest fruit earlier and to make it marketable soon. The study was carried out to investigate the seedless effect of GA3 150 ppm on star fruit and biochemical and nutritional quality by applying dipping method. Gibberellic acid (GA3) and bark stress play a significant role in fruit enlargement and development. It had been found that the GA3 150 ppm showed bigger sized fruit and made 75% seedless (aborted seed) as compared to the bark stress and control. Fruit/bunch was higher at GA3 150 ppm as well as lower fruit drop percent compared to other treatments. Glucose, inverted sugar, fructose and pH were found higher in the distal end of the fruit than in the middle and proximal end of the fruit. Total Soluble Solid (TSS) content was higher in GA3 150 ppm and bark stress treated fruit than the control. Moreover, antioxidant as vitamin c and polyphenol content were higher in GA3 150 ppm and bark stress treated fruit than the control. The results showed that GA3 150 ppm using dipped technique was the best for seedless fruit production, enlargement of fruit size and improve the better biochemical content.
