Morphology and physiology of strains of <i>Sporobolomvces roseus</i> and <i>S. pararoseus</i> isolated from winter wheat seeds was studied. Most of strains <i>S. roseus</i> and all strains of <i>S. pararoseus</i> exhibited a positive starch reaction, and showed a tendency to lose the ability of formation of ballistospores. In some strains of <i>S. pararoseus</i> adaptation to nilratc nitrogen occurred.

Morphology and physiology of strains of <i>Candida albicans</i> and <i>C. tropcalis</i> isolated from winter wheat seeds were studied. Three groups of strains of <i>C. albicans</i> were differentiated. Strains of <i>C. tropicalis</i> differed in some morphologlcal and physiological details from a standard description of the species.

Morphology and physiology of strains of <i>Cryptococcus laurentii</i> var. <i>magnus</i> and <i>C. albidus</i> var. <i>albidus</i> isolated from winter wheat seeds was studied. It was concluded on the basis of morphological similarity that these fungi were closely related. Resting spores of a "dangeardien'' type were found in <i>C. laurentii</i>, while in some cultures of <i>C. albidus</i> unusually large resting spores were dis00vered.

In connection with the constant growth of demand for high-quality food products, there is a need to develop effective methods for storing agricultural products, and the registration and predicting infection in the early stages. The studying of the physical properties of infected plants and seeds has fundamental importance for determining crop losses, conducting a survey of diseases, and assessing the effectiveness of their control (assessment of the resistance of crops and varieties, the effect of fungicides, etc.). Presently, photoluminescent methods for diagnosing seeds in the ultraviolet and visible ranges have not been studied. For research, seeds of winter wheat were selected, and were infected with one of the most common and dangerous diseases for plants—fusarium. The research of luminescence was carried out based on a hardware–software complex consisting of a multifunctional spectrofluorometer “Fluorat-02-Panorama”, a computer with software “Panorama Pro” installed, and an external camera for the samples under study. Spectra were obtained with a diagnostic range of winter wheat seeds of 220–400 nm. Based on the results obtained for winter wheat seeds, it is possible to further develop a method for determining the degree of fusarium infection.

Non-thermal atmospheric pressure plasmas have been recently explored for their potential usage in agricultural applications as an interesting alternative solution for a potential increase in food production with a minor impact on the ecosystem. However, the adjustment and optimization of plasma sources for agricultural applications in general is an important study that is commonly overlooked. Thus, in the present work, a dielectric barrier discharge (DBD) reactor with coaxial geometry designed for the direct treatment of seeds is presented and investigated. To ensure reproducible and homogeneous treatment results, the reactor mechanically shakes the seeds during treatment, and ambient air is admixed while the discharge runs. The DBD, operating with argon and helium, produces two different chemically active states of the system for seed modification. The temperature evolution was monitored to guarantee a safe manipulation of seeds, whereas a physiological temperature was assured by controlling the exposure time. Both treatments led to a remarkable increase in wettability and acceleration in germination. The present study showed faster germination acceleration (60% faster after 24 h) and a lower water contact angle (WCA) (82% reduction) for winter wheat seeds by using the described argon discharge (with air impurities). Furthermore, the treatment can be easily optimized by adjusting the electrical parameters.
