The Study of Luminescence Spectra of Seeds of Crop Species for Diagnostic Quality

In this chapter, optical luminescent biological objects diagnostics methods and biotissues are considered. According to the previously developed method, excitation and photoluminescence spectra agricultural plants seeds, including cereals, legumes, fodder, technical, and vegetable, were measured. The typical excitation spectrum lies in the range of 355-500 nm and has two maxima: the main one at 424 nm and the side one at 485 nm. The luminescence spectrum lies in the range of 420-650 nm and has a maximum in the region of 500-520 nm. The maximum luminescence is less pronounced than in the excitation spectrum. The measured spectral luminescence characteristics forage plants seeds by scarification. Due to the scarification forage plants seeds spectral characteristics increase. In Galega seeds with multiple scarification, observed qualitative changes in the excitation spectrum was associated with the appearance of a new maximum at a wavelength of 423 nm. Similarly, for clover seeds, the obtained results can be used to create seed diagnostics devices.
