“…10 g kg −1 CaC2 (1.94%) and 15 g kg −1 CaC2 (1.92%) were significantly the highest value (Table 2). Several cases also mention that PWL can be suppressed by using 1-MCP derived compounds as reported by Khan et al (2016). The results reported that 500 nL L −1 1-HCP could inhibit PWL of 9.85% in hybrid tomato fruit.…”

“…According to Wang et al (2020a), the inhibiting action of the new protein on ethylene signal transduction is extremely strong that cannot be overcome by ET and CaC2 and a new protein acts as a repressor. Khan et al (2016) reported that the treatment given 1-Hexylcyclopropene (HCP) was brighter on hybrid tomato than the control, with a value of 51.89. 1-HCP is a ripening inhibitor compound similar to 1-MCP.…”

Abstract. Khairi A, Murti RH, Irwan SNR, Putra ETS. 2023. Physicochemical properties in NOR tomato line MA 131-6-3 after treated with ethephon and calcium carbide induced ripening. Biodiversitas 24: 3029-3037. Tomato fruit Postharvest Losses (PHL) from rotting, Physiological Weight Loss (PWL), inadequate nutrition, and other factors can lower fruit quality. Tomato is included as climacteric fruit which shows a significant increase in respiration and ethylene. The use of tomato with an extended shelf life due to genetic engineering, such as a Non-Ripening (NOR) tomato, can lower PHL. This experiment was carried out to evaluate physicochemical characteristics of NOR tomato fruit (lineMA 131-6-3 as result of selection F6)during postharvest after being treated by Ethephon (ET) (375, 750, 1,125, and 1,500 ppm), calcium carbide (CaC2) (5, 10, 15, and 20 gkg?1), and control. The experimental design was arranged in Randomized Completely Block Design with three replications.The ambient temperature was 28.30±1.75°C and relative humidity of 60.69±2.33%. The results showed the fruit ripening and physicochemical altered with CaC2 treatment, then followed by yellow but did not alter to the red color for all treatments. The value of reduction sugar, respiration, ethylene, PWL, and pH increased, meanwhile the fruit firmness decreased caused by CaC2. Furthermore, ET could increase rotting during storage.

“…TSS, TTA, and TSS:TTA ratio are shown in Table 3 and the data showed no significance. TSS:TTA ratio, research by Khan et al (2016) shows that fruit ripening inhibitors such as 1,000 nL L -1 1-hexylcyclopropene (HCP) can reduce TSS:TTA ratio by 7.22 compared to a control of 8.80. A decrease in TSS was also found in Nasef ( 2018) study with cucumbers (Cucumis sativus L.) dipped in hot water at 25 °C (control), 45 °C, and 55 °C.…”

“…Hue values are categorized as 0• = red to purple, 90• = yellow, 180• = bluish to green, and 270• = blue. Chroma is defined as the intensity of color saturation from dull to vivid color (low to high values, respectively) (Khan et al, 2016). Classification of color and mature stages of tomato fruit according to redness values such as -0.59 to -0.47 (green), -0.47 to -0.27 (breaker), -0.27 to 0.08 (turning), 0.08 to 0.60 (pink) 0.60 to 0.95 (light-red), and 0.95 to 1.21 (red) (Salas-Mendéz et al, 2019).…”

Ethephon and calcium carbide are artificial ripening compounds that are often used to faster fruit ripening during postharvest. These two compounds were induced in non-ripening (NOR) tomato fruit line MA 131-6-3 because it produced endogenous ethylene and lower respiration. This study aimed to determine the effect of ethephon and calcium carbide on postharvest losses of NOR tomatoes for 14 and 28 days after treatment. Exogenous application of 1,500 ppm ethephon and 15 g kg-1 was given to NOR tomato fruit of line MA 131-6-3 and ambient conditions at temperature 28.08±1.80 °C and relative humidity 75.67±2.09%. This experiment was carried out in Sidoarum village, Godean district, Sleman regency, Special Region of Yogyakarta province, Indonesia, in 125 m above sea level. As a result, ethephon can increase fruit rotting. Furthermore, calcium carbide can accelerate metabolism which has an impact on physiological loss in weight, changing color to yellowish (b*), increasing vivid color (chroma), but the color of tomato fruit cannot turn red.
