NETSUKE AS A RESOURCE OF INFORMATION ABOUT SPECIES DIVERSITY OF LAGENARIA SICERARIA (MOLINA) STANDL
Description
In the article, with a descriptive method and a method of analysis and synthesis, we have conducted a study of species diversity of Lagenaria on the basis of a miniature sculpture of netsuke. In Japan and China, in the period from the 17th to the 20th century, the most common was 9 species. The biological peculiarities of some rare species of lagenaria has been described

THE ROLE OF SCIENTIFIC ILLUSTRATION IN THE HISTORY OF BIOLOGY
Description
Illustration is an important part of scientific work and educational process. They help us understand studying material and see the different connection among things. The different types of illustration were analyzed and we also demonstrated illustrations in scientific world, education materials and the role of abstraction in scientific illustration

Description
The article considers the new method for recovery of P. arbelaeziion intact material on the basis of grafting into endogenous pathogens resistant Passiflora species in vivo. The influence of the explants origin depending on the stock of intact plants on the development of regenerated P. arbelaezii under in vitro condition is examined

Description
The research of the territory adjacent to Novocherkassk state district power station, for the content of polycyclic aromatic hydrocarbons (on an example of benzo(a)pyrene) is presented. The benzo(a)pyrene content in soils has been determined with a method of subcritical water extraction. The content of benzo(a)pyrene in soils of the territory adjacent to Novocherkassk state district power station has been estimated. It is shown, that contents of benzo(a)pyrene excess over maximum permissible concentration in soils of five-kilometer zone around the companies

Description
The analysis of the variability dynamics of recombination frequency in the population of splitting F2 interspecific and intraspecific tomato hybrids has been carries out. It was discovered that recombination frequency depends on the components of cross breeding. It has been established that it is reasonable to use mutant forms of Мо 393, Мо 628 and interspecific hybrid F1 Мо 628 × L. esculentum var. racemigerum in selection process as an inductor of genotypic variability

BIOLOGICAL FEATURES OF THE CHINESE DATE (UNABA) IN WESTERN CISCAUCASIA
Description
The article presents the results of the researches of growth and fructification of grades and forms of the Chinese date (unaba) in the Prikubansky zone of fruit growing. The biological features of the varieties and forms of unaba which are selected during researches on a research field of Kuban state agrarian university in the Prikubansky zone of fruit growing are considered. Novelty of work – such researches were conducted in Kuban for the first time

Description
In herbaceous communities of annual crops dominate clean sowings, which are characterized by high productivity. However, it is very poorly adapted, different weak transformation of matter and energy and stronger exposed to stressful situations as compared to natural systems. In agroecosystems only structural diversity can supporting many processes on a much aligned level. In agrolandscape system creates mixed sowings that are practiced in forage production of many areas. Great importance is the selection of crops for joint sowing because the relationship of species in created systems are poorly investigated and documented in the literature is not enough. Investigations were carried out on experimental plots on the farm called "Zavety Ilyicha" of the Leningrad district and training farm called "Kuban" in Krasnodar. Formation of joint sowings in different moistening conditions, level of fertility, chemical and physical condition of the soil is a very big problem. Cultivation of different cultures in joint sowings significantly influences the terms the onset of main phases of vegetation in certain species. For example, the placement of sorghum between rows of soybean noticeably extended the period of its vegetation (5-7 days); acceleration of interphase periods was marked for amaranth; height of plant noticeably was changed, leaf area was varied, indicator of competitive features of individual species was differed. The existence of the relationship between the method of sowing crops, their farming practices and composition of species and population of microflora, mesofauna of soil, yield of dry matter and grain was observed
