Abstract:
:Subsequent production of amylase is severely inhibited if barban [4-chloro-2-butynyl N-(3-chlorophenyl) carbamate] is added to embryo-free half seeds of barley within 4 to 5 hours after gibberellic acid treatment of these seeds. Thirty to 50 mg/L concentrations of barban are effective. Barban inhibition is non-competitive with respect to gibberellic acid. Addition of barban 7 hours or more after gibberellic acid treatment is almost without effect. The delay between gibberellic acid treatment and amylase formation tends to become shorter with more prolonged imbibition periods. Regardless of imbibition period, susceptibility to barban is lost within 7 hours after gibberellic acid treatment. Other herbicidally active phenylurethanes are also inhibitors, but none are as effective as barban. Phenethyl alcohol and 2 arylcarbamates can act as inhibitors.
