To identify and select snow mold-resistant genotypes, 50 varieties of winter soft wheat (Triticum aestivum L.) various origins were tested under conditions severe biotic stress. The study was conducted on natural infectious backgrounds (factor A) in 2019-2020 2020-2021 B) the Republic Tatarstan. predecessor is pure steam. Sowing dates are optimal for zone. Local populations Microdochium nivale ...

For the purpose of understanding mechanism grain refinement in cast metal by mechanical vibration, demonstration tests were conducted using an ammonium chloride solution. Ammonium solution and molds with various shape prepared for water model experiment. In case open mold, crystals crystallized on mold wall grew toward center without vibration. However, when vibration was applied, countless gen...

In this study, the effect of ultrasonic vibration on mold filling ability, microstructure, and mechanical properties aluminum alloy during solidification is investigated. Microstructure were compared with casting without ultrasonic. Grain refinement an increase in obtained due to vibration. The material used for research was ADC12 alloy, frequency 20 kHz. carried out SKD11 steel molds. It found...

During solidification of metallic alloys, coalescence leads to the formation of solid bridges between grains or grain clusters when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behavior of solidifying alloys and to the prediction of solidification cracking. Coalescence starts at the coherency point when the grains begin to t...

During recent years many new and extended uses have been developed for fungal enzymes. Prominent among these are applications in the fields of food manufacturing, textile processing, and in the manufacture of malt beverages and industrial alcohol. Although certain microorganisms are capable of elaborating amylases when grown under submerged conditions either aerobically (Waldmann, 1942) or anae...

Funnell-Harris, D. L., and Pedersen, J. F. 2011. Presence of Fusarium spp. in air and soil associated with sorghum fields. Plant Dis. 95:648-656. Sorghum grain, valuable for feed, food, and bioenergy, can be colonized by several Fusarium spp.; therefore, it was of interest to identify possible sources of conidia. Analysis of air and soil samples provided evidence for the presence of propagules ...

The article presents the results of studies field resistance winter triticale varieties to a number diseases that have significant impact on formation grain yield. It was established Talva 100, Kornet, Student had no signs damage by ergot, powdery mildew. 100 and Cornet were weakly affected septoria, fusarium snow mold, ear fusarium. moderately leaf rust. variety in relation studied more septor...
