Model hi 96801

Total soluble solids (TSS) were measured with juice obtained from 10 fruits per treatment by a method modified from Lara et al. [35 (link)]. It was determined with a digital refractometer (Model HI-96801, Hanna Instruments, Leighton Buzzard, Bedfordshire, UK), and results were expressed as Brix in juice at 25 °C. An appropriate quantity of each sample was placed on the digital refractometer’s prism plate, and the reading appearing on the screen was directly recorded as total soluble solids.

For each application, the fruits were harvested and weighed on a 0.1 g sensitive balance, and the yield was determined by dividing the total yield per plot by the number of plants. The average fruit weight was determined by dividing the yield amount by the number of fruit. The number of fruits per plant was calculated by counting the harvested fruits and dividing them by the number of plants in the plot. Ten fruits selected by chance were crushed and juiced, and the amount of soluble solids contents (SSC) was determined with the help of a digital refractometer (Model HI-96801 Hanna GmbH, Wöhringen, Germany). Ten randomly picked fruits were crushed and juiced, and the electrode tip of the pH meter (Hanna-HI 98103, Hanna GmbH, Wöhringen, Germany) was placed in the juice. When the value displayed on the screen becomes stable, it was saved. It was calculated in terms of citric acid by titration technique in 10 mL fruit juice obtained from random fruits.
