Plant Growth Retardant B-995: A Possible Mode of Action.
Inhibition of shoot elongation in dwarf and tall peas by the 1,1-dimethylhydrazide of succinic acid (B-995) was correlated with the inhibition of the oxidation of tryptamine-2-C(14) to indoleacetaldehyde-2-C(14) in homogenates prepared from epicotyls of young plants treated with B-995. The growth-retarding action of B-995 is attributed to the formation of 1,1-dimethylhydrazine in vivo. This hydrazine strongly inhibited tryptamine oxidation by pea epicotyl homogenates.
