abstract = "The temporal course of photosynthetic induction was investigated on Chrysanthemum morifolium under dynamic light and temperature conditions to evaluate the effect of climatic variables on photosynthetic induction. The Plant material was grown under uniform, controlled conditions and analyzed for photosynthetic induction. Gas exchange measurements were used to investigate the rate of induction and the opening of stomata. It was determined that induction equilibrium for C. morifolium at varying temperatures under dynamic light conditions was reached within 15 to 45 minutes except at saturating light intensity. For the same photon irradiance, the momentary state of induction equilibrated was higher approximately at 30° C and it decreased as temperature increased. The interaction effect of irradiance and temperature on induction equilibrium was not significant. The rate of photosynthetic induction and the time that it reached its 90{\%} value (t90) was influenced by irradiance significantly. The light history of a leaf had a significant effect on t90, which indicated that an equilibrium state of induction will not always be reached within the same time. The effect of temperature on photosynthetic induction was associated with stomatal conductance of the leaf prior to the onset of light, rather than the biochemical basis of the induction kinetics.",
