“…It is presumed that the content of the functional substance would have increased as the activity of the cell increased. As we found, it has been reported that the mixed treatment of GA3 and TDZ in 'Pione' significantly increased TPC compared to the single treatment of GA3 (Lee et al, 2003). Antioxidants are compounds that help to protect cells from damage caused by free radicals, which are unstable molecules that can damage DNA and other molecules in the body (Martemucci et al, 2022).…”

This study was conducted to investigate the effect of treatment conditions of plant growth regulators on the marketability of ‘Red Dream’, a triploid grape. In order to achieve the purpose of this study, gibberellic acid 3 (GA3) 100 ppm single use treatment group was set as a control group. In addition, the fruit characteristics expressed when cytokinins such as thidiazuron (TDZ) or forchlorfenuron (CPPU) 2.5 ppm or 5.0 ppm mixed with GA3 100 ppm were compared with the control group. Cluster weight was commonly higher in the mixed treatment of TDZ or CPPU than in the GA3 single use treatment, and it was found that the cytokinin mixed treatment could effectively induce the enlargement of ‘Red Dream’ berries. Although the harvesting period was slightly delayed compared to GA3 single use treatment in the case of mixed treatment of GA3 and TDZ or CPPU, there was no inhibition of coloration, soluble solid sugar content and functionality, which are important indicators of marketability. In particular, in the GA3 100 ppm + TDZ 5 ppm treatment group, where the enlargement of fruits was the largest, the occurrence rate of non-commercial berry was also found to be the lowest. Therefore, it is expected to contribute to strengthening the marketability of ‘Red Dream’ if such plant growth regulator treatment condition is applied during cultivation.

This study evaluated the effects of gibberellic acid (GA 3 ) on the growth and quality of creeping bentgrass (Agrostis palustris Huds.). Experimental treatments included a No application of fertilizer and GA 3 (NFG) Control [3 N active ingredient (a.i.) g/m 2 ], 0.3GA 3 (GA 3 0.3 a.i. mg/m 2 / 200 mL), 0.6GA 3 (GA 3 0.6 a.i. mg/m 2 /200 mL), 1.2GA 3 (GA 3 1.2 a.i. mg/m 2 /200 mL), and 2.4GA 3 (GA 3 2.4 a.i. mg/m 2 /200 mL). Additionally, the study included a 1.5N +GA 3 experiment with similar GA 3 treatments combined with 1.5N a.i. g/m 2 : NFG, Control (3N a.i. g/m 2 ), 1.5N+ 0.3GA 3 (1.5N a.i. g/m 2 +GA 3 0.3 a.i. mg/m 2 /200 mL), 1.5N+0.6GA 3 (1.5N a.i. g/m 2 +GA 3 0.6 a.i. mg/m 2 /200 mL), 1.5N+1.2GA 3 (1.5N a.i. g/m 2 +GA 3 1.2 a.i. mg/m 2 / 200 mL), and 1.5N+2.4GA 3 (1.5N a.i. g/m 2 +GA 3 2.4 a.i. mg/m 2 /200 mL). Compared to the NFG, turf color index chlorophyll content was not significantly different (p< 0.05). However, shoot length in 1.2GA 3 , 2.4GA 3 , 1.5N+ 0.3GA 3 , 1.5N+0.6GA 3 , 1.5N+1.2GA 3 , and 1.5N+2.4GA 3 treatments increased by 0.8%, 10.6%, 5.15%, 8.3%, 13.5 %, and 21.6%, respectively, compared to the control. As compared to the control, clipping yield in 1.5N+1.2GA 3 and 1.5N+2.4GA 3 treatments increased by 7.1% and 14.3 %, respectively. These results indicated that GA 3 application increased shoot length, with the 1.2GA 3 treatment showing shoot length similar to the control (3N a.i. g /m 2 ).

This research was conducted to investigate effect the plant growth regulators (PGRs) on the characteristics of fruit and flesh softening, using GA3 and thidiazuron (TDZ) treatments in 'Heukboseok' grapes. The total yield obtained under PGR treatment was 88.3% lower than the target production when a single treatment with GA3 of low concentrations was used, but the expected yield was recovered by combined treatment with TDZ and GA3. When harvested on the basis of color, the harvest rate up to 100 days after full bloom (DAFB) was low with the GA3 single treatment, but was increased by the addition of TDZ, with the second TDZ mixed treatment being particularly effective. The soluble solids content in the PGR-treated samples demonstrated no significant changes after 90 DAFB, while the acidity content decreased rapidly starting from 90 DAFB. Measured on the basis of sugar and acidity content, maturity was reached much earlier in treated fruit than in the non-treated fruit. Firmness was maintained at a higher level until the final harvest time after PGR treatment compared to untreated grapes according to epidermis thickness and flesh density increase to activity cell division and expansion by GA3 and TDZ. In particular, the fruit quality was improved based on the delay of softening in primary and secondary treatments of 25 mg･L -1 GA3 + 2.5 mg･L -1 TDZ. The production of seedless fruit was difficult, even with the inclusion of TDZ, reaching the highest seedless rate of only 65.5%. Fruit cracking was rare, occurring at a rate of about 0.0~0.9% in all treatments. Accordingly, 'Heukboseok' grapes should be harvested within 100 days after full bloom (DBFB) before a rapid decrease of firmness, conferred by primary and secondary treatments with 25 mg･L -1 GA3 + 2.5 mg･L -1 TDZ.Additional key words: harvest rate, fruit density, fruit softening, plant growth regulator
