Gibberellic acid: a growth factor in the unicellular alga Gymnodinium breve
Science (New York, N.Y.)
|August 7, 1970
Abstract:
Gibberellic acid stimulates growth in the unicellular alga Gymnodinium breve (dinoflagellate). The maximum effect was obtained with 10(-7) molar gibberellic acid, whereas concentrations greater than 5 x 10(-7) mole per liter were inhibitory. The effect of the compound is observed as a marked shortening of the lag period, which is normally 6 to 8 days after innoculation.
