Résumé : Bulbs were obtained on onion plants cultured in vitro. No bulbing happened under long days with fluorescent light and 30–40 g l−1 sucrose. Bulb formation was mainly dependent either on sucrose concentration in the culture medium, or on light spectral composition. Raising the sucrose concentration from 40 to 120 g l−1 increased plant basal swelling and stopped further vegetative development. These plants were not dormant. When fluorescent light was enriched in incandescence during a long day period, bulbs were obtained in two months and underwent a consecutive dormancy.
