Blue radiation stimulates photosynthetic induction in Fagus sylvatica L

Original language description

This study was designed to test the hypothesis that the spectral composition of incident radiation can affect photosynthetic induction, since B photons (B; ?max = 455 nm) stimulate stomatal opening and are more effectively absorbed by leaves than R photons (R; ?max = 625 nm). Different stages of photosynthetic induction, primarily determined by the photo-modulation of Rubisco activity and stomata opening, were investigated in dark-adapted leaves of Fagus sylvatica transferred to saturating irradiance [800?mol(photon) m?2 s?1] at B/R ratios of 1/3, 1/1, or 3/1. Photosynthesis was induced faster by irradiance with a high B/R ratio (3/1). However, there were no differences in induction between leaves receiving equal (1/1) and low (1/3) B/R ratios. Electron transport was highly sensitive to radiation quality, exhibiting faster induction kinetics with increasing B/R ratio. In contrast, the kinetics of stomatal opening was independent of the spectral composition of incoming radiation.
