Abstract
Uniconazole reduced growth of etiolated mung bean seedlings and increased lateral root formation. Ethylene production for whole seedlings was reduced by 80% within 24 h after treatment and 1-aminocyclopropane-1-carboxylic acid concentrations were reduced by approximately 40% in 12 h. Uniconazole treatment increased spermine levels by 100% by day 4, whereas spermidine and putrescine levels were not affected. Uniconazole, by inhibiting ethylene synthesis, may be increasing spermine levels, which in turn stimulate formation of root primordia.
