Effect of gibberellic acid on bolting and flowering of carrot ( Daucus carota L.)

GA 3 sprays applied to carrot plants at different growth stages stimulated leaf growth and inhibited root growth. Stem elongation was promoted by GA 3, in particular at higher temperatures. Plants bolting after GA 3 application deviated mostly from normal bolters by the formation of a short thickene...

More Information
Summary:GA 3 sprays applied to carrot plants at different growth stages stimulated leaf growth and inhibited root growth. Stem elongation was promoted by GA 3, in particular at higher temperatures. Plants bolting after GA 3 application deviated mostly from normal bolters by the formation of a short thickened stem, but started flowering only occasionally. GA 3 applied at a lower, vernalizing temperature (10°C) inhibited flowering.
