Evaluation of the Crop Capacity, Ecological Stability, and Plasticity of Winter Wheat Cultivars Under Conditions of the Nizhny Novgorod Oblast Russ. Agricult. Sci. Pub Date : 2020-09-07 L. K. Petrov
AbstractEvaluation of winter wheat cultivars has been carried out in relation to their crop capacity, ecological stability, and plasticity under conditions of the light grey forest soils of the Nizhny Novgorod oblast. In 2012–2016, the crop capacity of the cultivars included into the study was 53.0 centner/hectare on average (V = 23.3%) varying from 16.3 to 89.2 centner/ha; the year-to-year and cultivar-to-cultivar

Biological Rationale for the Protein Growth Stimulant Application to Increase Wheat Yield and Assessment of Grain Quality Using Microfocus X-ray and Optical Imaging Techniques Russ. Agricult. Sci. Pub Date : 2020-09-07 L. E. Kolesnikov; M. I. Kremenevskaya; N. S. Priyatkin; M. V. Arkhipov; M. V. Kiselev; Yu. R. Kolesnikova; I. E. Razumova
AbstractA new plant growth stimulant was developed according to the technology engineered by the scientists of ITMO and SPBGAU Universities. The biological effectiveness of the preparation was assessed by measuring 20 wheat productivity parameters and 16 parameters of various types of pathogenesis formed during the progress of root rot caused by Helminthosporium, different types of rust, powdery mildew

Cytogenetical and Physiological Effects of L-tryptophan in Onion ( Allium cepa L.) Exposed to Salt Stress Russ. Agricult. Sci. Pub Date : 2020-09-07 Dilek Çavuşoğlu
AbstractIn this study, 10 mg L–1 L-tryptophan effects on the seedling growth (fresh weight, radicle length and radicle number), seed germination, chromosomal aberrations and mitotic activity in Allium cepa L. germinated in salinity (0.175 M NaCl) conditions were investigated. In only L-tryptophan medium, the radicle length and radicle number of the seedlings were partially reduced compared to the control

Wheat-Linen Flour: Conditions for Producing and Biochemical Features Russ. Agricult. Sci. Pub Date : 2020-09-07 G. N. Pankratov; E. P. Meleshkina; I. S. Vitol; I. A. Kechkin; Yu. R. Nagainikova; S. N. Kolomiets
AbstractA study into the preparation and grinding of a grain mixture containing 7% flax seeds was carried out in order to obtain a composite wheat-flax flour in which the entire biopotential of flax seeds was preserved. It was revealed that the preparation of the components of the grain mixture should be carried out independently, in parallel flows. The optimal extraction conditions for the wheat-flax
