Modelling And Simulation In Photoautotrophic Micropropagation

In conventional micropropagation, a lighting cycle (16 photoperiod + 8 h dark period) of 24 h is usually used. If the ratio of photoperiod to dark period remains unchanged with different lighting cycles, the photosynthetically active radiation received by the cultures and the electricity consumption per day are approximately the same. However, the growth of the cultures may be different because Ci is affected by lighting cycle.

Figure 3. Simulated time courses of CO2 concentration inside the vessel (C) as affected by lighting cycles (24, 6, 1.5, and 0.375 h, with same ratio of photoperiod to dark period). Solid and dash lines represent simulated time course of Ci on days 7 and 21, respectively. Circle and triangle symbols represent measured Ct on days 7 and 21, respectively (Niu et al., 1997).
