Nitrile formation (%) of control and MeJA-treated pak choi. Nitrile formation (%) is shown as the relative ratio of nitrile to the total hydrolysis product formed (sum of isothiocyanates and nitriles). Data are presented as the mean concentration ± standard error (n = 3). Asterisks (*) above the error bar indicate a significant difference between treatments within same glucosinolates substrate by Student’s t-test at p ≤ 0.05. ^z Substrate glucosinolate used in the estimation of nitrile formation activity [nitrile percentage (%) out of total hydrolysis products].
