Abstract
The main purpose of the work was to study the linearly polarized light impact on the maize plants development. The other purpose was to confirm the model proposed earlier. The methods used in this work include the development of LED light sources, the polarization parameter (degree of polarization) assessment and statistical analysis. Maize (Zea mays L.) plants, Hansatech FMS 1+ pulsed fluorimeter and software TXP Series Instrumentation were used. Plants were grown under white light (WW) with intensity of 200 µmol m–2 s–1. The morphometric parameters measured on the 21st day demonstrated that maize plants of different varieties grown under linearly polarized light developed better than under non-polarized light conditions. In addition, the fact was confirmed by chlorophyll fluorescence measurements. The mechanism has been proposed to explain significant polarized radiation impact on maize, according to which this impact depends on the shape and arrangement of the leaf epidermal cells. The monocotyledonous maize plants have leaves with an ordered arrangement of epidermal cells in comparison with dicotyledonous plants, which cells placed in chaotic order and have no certain shape. Thus, the maize cells layer can transform linearly polarized radiation into elliptically polarized radiation, thus latter should be more efficiently absorbed by the chiral chromophores of photosensitive structures in underlying photosynthetic cells.
