    Photochemical activity in developing pea (<i>Pisum sativum</i> L.) cotyledons depends on the light transmittance of covering tissues and the spectral composition of light by G. N. Smolikova, N. V. Stepanova, A. M. Kamionskaya, S. S. Medvedev

    Published 2023-12-01
    “…PAM fluorometry was used to quantify the photochemical activity in plant tissues: this technique is handy for evaluating the efficiency of converting light energy into chemical energy through the analysis of the kinetics of chlorophyll fluorescence excitation and quenching. On average, a photochemically active green leaf of pea transmitted 15 % of solar radiation in the 390–760 nm, blue light was delayed entirely, and the transmitted red light never exceeded 5 %. …”
