“With increasing concentrations of MeJA in spray applications to broccoli florets, concentrations of the glucosinolates glucoraphanin, gluconasturtiin and neoglucobrassicin and the isothiocyanate sulforaphane as well as anticancer and anti-inflammatory bioactivities as measured by QR induction and inhibition of nitric oxide (NO) production respectively were significantly increased.”
