Shoot and bulb induction of hyacinths under the influence of varying light treatments (blue, green, yellow, red, far-red and UV irradiation) was studied in long-term in vitro cultures. Leaf explants were cultivated on solid MS medium containing sucrose or glucose (90, 180 or 360 mM). The light as well as the types and concentrations of carbohydrates affected regeneration. Blue light stimulated growth and development of adventitious shoots and buds regardless of carbohydrate type, while the highest number of bulbs was obtained under red or white light and darkness as well as low and moderate concentrations of sucrose in medium. On average, 360 mM glucose yielded the highest proliferation rate of adventitious bulbs, followed by 180 mM sucrose. Blue light and UV irradiation promoted development of chlorophylls. Blue light also increased the total amount of anthocyanins. Far-red light reduced chlorophyll content.
