Abstract
Diurnal light intensities were determined in the understory of secondary deciduous forest in Hiratsuka Japan. In early spring total photon flux was 80 times higher than those in summer. Strong light was characterized by wide ranges of fluctuations with slow cycles. In early spring light intensities fluctuated between 113 and 913 μmol photons m−2 s−1 with ca. 10 min cycles, although it did between 30 and 250 μmol photons m−2 s−1 with 2.5 s cycles in summer. Japanese lily (E. japonicum) inhabiting there blooms only in early spring and can acclimate to those light conditions. Acclimated plants to the simulated light in the understory maintained 13% higher photosynthetic rates than those without acclimation, and showed rapid induction at the beginning of the strong illumination.
