Results of the long studies of the horizontal structure of different plantings in Mid-Siberia are presented in article. The horizontal structure of the plantings is characterized with significant variety of trees placing. Maximum full (normal) plantings of pines with uniform structure are characterized by casual trees placing. The modal plantings of pines with determined probability were characterized by group placing of trees.
Cedar and fir plantings with different structure have a group distribution of trees and young plants that is normal for the nature of these woods.
Vitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection
Clone selection of usually zoned grades of grapes nowadays is made in all countries of the developed wine growing and this way increases not only productivity level, but also quality of raw materials. Process of clone selection is complicated by long-term finding-out of presence of changes of genotypical grade environment. For simplification of selection of a highly productive protoclone of selected grades use of the advanced methods of genetic marking of pluses-transgressions and selection of nucleotidically changed plants with a complex of high values of valuable quantitative signs is necessary
Chemical disinfectants at recommended doses do not impair the viability of Planriz biological agent when applying them in the tank mixture. Planriz reduces injuries of the spring wheat diseases and increases the productivity of culture when mixed with chemicals
In the article the questions of grape plantings spareness elimination by the ways of filling-up saplings with cuttings of scleroticе rods, green arms or a bush and reinoculation of bushes. With the preventive purpose, for reduction of plantings spareness degree on a vineyard, stamping of arms, application of potash fertilizers in the summer and in the autumn, stopping of watering in due time, normal loading of bushes with a crop and harvesting in due time are done, i.e. all the conditions for the best ripening of a rod and preparation of plants for winter are made
In article the review of results of studying of influence of harvest date of fruits on storage period of fruits of the zoned grades of Golden Delicious and Renet Simirenko apple-trees is given. As a result of this work, the efficiency of influence of harvest date of fruits on quality and duration of storage in usual atmosphere is proved
In the article the characteristics of 64 perspective grades of grapes which are valuable for production use in southern regions of Russia are resulted. Color images in the form of photos of these grades of grapes are presented in earlier published section 8 of the given collective monograph
The design procedure of a parity irrigated and dryland shares of farmland on various types of agrolandscapes, which develops from a recommended parity of environment formatting and environment destroying grounds, providing protection of soils from erosion and supporting their fertility at certain level is resulted in article
Extrasol contains strains of Bacillus subtilis bacteria which stimulates growth of plants. At processing of seeds and leaves of rice, the efficiency of plants consi-derably increased - on the average at processing of seeds for 8-16 %, leaves - on 13-31%, in common - on 20-47 %. Various reaction of sorts of rice to processing is noted
The polymorphism is the diversity of varieties in ampelografy - the presence simultaneous permanent in the population of two or several phenotypic and genotype differing groups of plants of one variety – i.e. clones. In viticulture the isogenic population is usually called “clone” and variety as the total of clones or forms – i.e. it is heterogenic. Polymorphism of varieties has big practical sense, as varieties-clones have the harmonic complementary adaptive ampelocenosis and higher economical effect for production. In the article the polymorphism of two heterogenic population - the group Pinot and Riesling, which are the best specimen of French and German viticulture is described on the phenotypic level of leaves
