REGENERATION OF ISOLATED BULB SCALE SEGMENTS OF HYACINTH* |
| Authors: | R.L.M. Pierik, J. Woets |
| Abstract:
Regeneration of hyacinth bulb scale segments in vitro was investigated under standard growth conditions. Bulblet regeneration was strongly promoted by placing the explants upside-down on the medium and increasing the length of the explants. Regeneration of bulblets was hardly affected by the concentration of macro-elements or glucose. The optimal temperature was 13 to 17°C. Continuous light inhibited regeneration as compared with darkness. IAA promoted bulblet regeneration, whereas kinetin slightly decreased it. Regeneration was decreased by GA3. A clear correlation between the number of bulblets per explant and the fresh or dry weight production of bulblets could not be found. | |
