A wide variety of molecular mechanisms have been proposed to explain the actions of the synthetic plant growth regulator maleic hydrazide (3). One of the most prominent of these theories holds that MH2 acts as a sulfhydryl reagent (7), and more recently it has been suggested that MH acts as a carbonyl reagent (12). The idea that MH might react with sulfhydryl groups was supported by reports that it can inhibit respiration in several plant tissues and can block several sulfhydryl enzymes (13). Several subsequent studies, however,
