Promotion of auxin- and gibberellin-induced elongation of epicotyl segments of Vigna angularis by short-chain carboxylic acids

Pollen tube growth is inhibited and promoted by long- short-chain carboxylic acids, respectively, but not affected formic acid. For auxin- gibberellin-induced elongation of in vitro cultured epicotyl segments adzuki bean (Vigna angularis), a series acids showed similar effects as that on pollen except acid the strongest promotive effect. The GA3 IAA-induced were additive both strongly inhibitors cellulose synthesis (coumarin) microtubule formation (colchicine). Formic acid, possibly incorporation into segments, prolonged promotion IAA segments. Based these results later advances our understanding metabolism role protecting against oxidative stress, possible stem discussed.
