INFLUENCE OF PLANT GROWTH CONDITIONS ON PHOTOSYNTHESIS PARAMETERS

Numerical modeling of the structure of wheat chloroplasts was carried out on the base of the images obtained by an electron microscopy. It was found that the plant structure, taking into account the absorption lines of chlorophyll molecules, can form zones of selective reflection and local peaks in the density of photon states. A comparison was made of spring barley under different growth conditions and different additional nutrition. The results obtained indicate a decrease in the order strength of thylakoids within chloroplasts. As a result, the disorder of the structure led to a decrease in the spectral characteristics. Thus, these studies lead to the consideration of plant chloroplasts as full-fledged biological photonic crystals
