영문 초록

This study is focused on the evaluation of growth parameters, total polyphenol content (TPC), chlorophyll content as well as the DPPH (1,1-diphenyl-2-picryhydrazyl) free radical scavenging activity of young barley seedling (YBS) affected by elicitation. Salicylic acid (SA), methyl jasmonate (MJ), amino acid liquid fertilizer (ALF) and microbial metabolism activator (MMA) were used. Elicitation was conducted for two times and various concentrations were used in this study. The result revealed that, MJ 1 ml/L treated-YBS gave the longest seedling length of 1.33 cm, followed by the ones treated with SA 1.38 mg/L and ALF 2 ml/L, respectively. ALF 3 ml/L treatment gave the highest fresh weight of 10 seedlings, followed by MJ 5 ml/L and SA 13.8 mg/L treatment with 1.56 g, 1.55 g and 1.53 g respectively. SA 138.12 mg/L elicitor treated-YBS gave the highest Chl a, Chl b content of 8.57 μg/mg and 3.83 μg/mg, respectively while the highest carotenoid content was found in MJ ml/L treatment with 1.62 μg/mg. Among elicitor treated-YBS, SA showed better TPC. The highest TPC was found in SA 1.38 mg/L treatment with 18.82 mg/g TAE. Likewise, SA 1.38 mg/L showed the highest DPPH free radical scavenging activity among all the treatments. However, the lowest TPC was found in ALF 1ml/L treated-YBS with 9.46 mg/g TAE, which was even lower than the control (14.31 mg/g TAE).
