Аннотация:The application of the infrared (IR) spectroscopy method to grain of maize inbred lines
with high-quality traits to determine possible conformational and functional properties
of their organic compounds is discussed. The IR spectrum of maize grain has been registered
in the following inbred lines: ZPPL 186, ZPPL 225 and M1-3-3 Sdms. The existence
of spectral bands varying in number, intensity, shape, frequency and kinetics has
been determined. These bands have been determined by valence oscillations and deformation
oscillations of the following functional groups: alkanes, alkenes, alkynes,
amides, alcohols, ethers, carboxylic acids, esters, aldehydes and ketones that are characteristic
for biogenic compounds of carbohydrates, vitamins, pigments and dietary
fibres. In such a way, possible conformational and functional changes in the grain components
of observed maize inbred lines could be detected. This was shown by total
parameters of infrared spectra of grain.
