This article describes quantitative evaluation of add-ing succinic acid in the bran substrate when cultivating Pseudomonas fluorescens
In the main collectors in the North-West Caspian we have found the concentration of priority chemical elements: in water - Zn, Cu, Mn, Co, B, Mo, Cr, Ni, Pb; in sediments - Zn, Cu, Mn, Cr, Ni, Pb. It was found that a common and characteristic feature of drainage water is a low concentration of these elements investigated (except Mn, B, Pb). In the bottom sediments collectors content of gross forms of Zn, Cu, Mn, Ni, Pb and mobile forms of Zn, Cu was below the MRL and the content of the gross forms of Cr and Mn mobile forms was a little higher
In this work we examine the type of inheritance, number and force of the genes participating in determination of a quantitative attributes of length, width of grain, weight of 1000 grains at hybrids from crossing of the Iranian variety of rice Ambarbu with varieties of Virazh and Boyarin. It is established, that distinctions between samples of length of grain made 3 pairs of genes, of width of grain – 1 pair genes, of weight of 1000 grains – 2-3 pairs genes
The article provides a review of biological traits that could be useful for selection of the walnut in diverse conditions of its growth. The most important aspects of species biology are described as they are of primary importance for breeding programs in the countries with
walnut crops
The article investigates the impact of waste of elevators on morphological parameters and productivity of winter wheat grown on black leached soil
This article reviewed the results of analysis of a balance of nitrogen, phosphorus and potassium in chernozem (typical black leached soil of Belgorod region) after two crop rotations by different cultivation technologies of agricultural crops. The balance of nutritional elements has been calculated and the optimal agro technology for deficitless balance of plant nutritional elements determined
In the article, the information of the influence of humival feed additive on hematologic parameters, development of a multichamber stomach, live weight, meat productivity, economical efficiency are resulted for growing of young sheep up to seven-month age
The results of development of rice breeding lines, carrying the wide range resistance gene to rice blast disease - Pi-40. For identification of the dominant allele of the gene the DNA - marker analysis was used. With co-dominant DNA markers plants from inbred populations that carry a dominant allele of this gene in the homozygous state were selected
According to the results of long-term evaluation of promising hybrids of lavender angustifolia the ability to predict the influence of abiotic factors on the yield and gathering of essential oil of inflorescences is shown. Correlations, agronomic stability and variability of the yield of hybrids are defined
The article deals with the problem of overgrowing of ponds and reservoirs. One way to reduce the intensity of development of plants is covering the territory with geosynthetic materials. Laboratory researches of geosynthetic materials are carried out. The optimum size of the layer of soil, which is loading geotextiles, was determined
