Table 2: Concentrations of monoterrepoids compounds in different table grape varieties at harvest in 2014 (\(\mu\)g/L). “nd” represented “Not detected”. “tr” represented “Trace amount”. Data were shown as means \(\pm\) standard deviations of duplicate tests. Values with different letters (a–f) on a row were significantly different based on [PERSON]’s multiple range test (\(p<\) 0.05).
