The results of breeding of lignified cuttings of varieties and forms of Feijoa in the humid subtropical of Russia are presented. Lignified cuttings cut from the top and bottom were covered with uterine of root-own plant varieties of "Superba", "8-10""0-01"and "D-1" and placed on the beds with different substrates: tea soil; peat + sand, perlite. It is established, that the lignified cuttings from the bottom of the overgrown Feijoa variety “Superba” were better rooted in the "tea soil," from the top of the shoots - on the substrate peat + sand. Lignified cuttings of all forms and types of plants studied rooted worse in perlite
The results of study of production process of winter wheat amid of changing of agro ecological conditions such as seeding time, level of initial fertility, fertilizer system and variety throughout 3 year-research are shown in the article. Five hypotethetical systems are pointed out with the help of factorial analysis. Detached varieties and research years are pointed out in terms of their factorial influence
This article describes performance analysis of using African swine fever virus (ASFV) recombinant protein p30 and p72 in indirect solid-phase Enzyme-Linked Immunosorbent Assay (ELISA) for investigation of antibodies formation by research of their level against African swine fever virus in porcine serum under the acute and chronicle process of disease
The search of resistance sources to the wheat stem rust pathogen among wheat collection material, its rare species and Aegilops (goat grass) was conducted. The samples resistant to the pathogen were detected. They have been studied on the artificial infectious background for three years and they are recommended for use in selection
In this article the changes of age and sexual structures of populations of a lake frog from ponds-evaporators of sugar factories are show. The are the low number of adult animals, the increase of frogs of morpha maculate and females
In the article the characteristic of age states of the rare species Oxytropis baschkirensis Knjasev (Fabaceae) is described in South Urals, and also biometric parameters of generative plants are resulted and their variability is estimated
In this article the influence of four nanometal oxides on tadpoles of lake frog in pure water and in low concentrations of sawage of sugar factory is considered. It is revealed the protecting action of three nanometals, characterized by an increase in growth rates and decrease in death rate of tadpoles in sawage of sugar factories
The article features a basic algorithm for determina-tion of tree health classes in terms of park planta-tions, which will reduce the effect of an expert's sub-jective judgment on the survey results
Researches of incubation parameters of meat hens eggs while treatment of embryos before incubation for 6, 12,18 day embryogenesis with coherent source of red light of laser Matrix and red light, in a range of the laser - gas-discharge lamp DNESG-500, are given in this work
