CHOPPER-LIGHT FOR SHOOT CULTURES

Abstract:
Chopper-Light, a special form of intermittent light, was applied to shoot cultures of deciduous woody plants. Growth parameters such as multiplication rate and biomass production showed that these shoot cultures could be cultured with half or even a third of lighting energy without a decline of these essential parameters. Light conditions were compared between a control treatment with continuous light and the Chopper-Light treatment regarding photon flux density per pulse (40 and 80 μmol m-2 s-1), the total light energy per day (4.6, 2.3 and 1.15 mol m-2 d-1) and pulse sequences (20 ms light / 20 ms dark, 100 ms light / 100 ms dark, 20 ms light / 40 ms dark).
