The analysis of use of glauconitic sand is provided in the article as a potential local fertilizer in the conditions of Kuban. The research of its agrochemical properties showed high value of this substance as fertilizers. In its structure we found macro - and microcells which are necessary for mineral nutrition of plants. Fractionation of phosphorus and potassium in various acids showed their different availability for the plants, which will help to consider glauconite as a fertilizer of prolonged action
On the basis of the researches aimed on improving of nutritional regime of chestnut soils in the system of field crop rotations, at the same time with traditional cultivation, it can be recommended to use direct sowing
Results of four-year (2004-2007) researches of
perspective technical grape varieties by contrast
zones of Krasnodar region : in central- Antaris,
Beisug, Cabernek, Clairette Temryk, Litdar, Merlok, Muscat Kuban, Rislinalk, Risling Kuban, Shardonek, in Anapa-Krasnostop AZOS, Rubin AZOS and to the memory of Zotkina, were cited in the article. It was shown their superiority under control varieties.
Ampelographical screening of gene pool was carried out in subzone Temryk on the plot of I.G. Karas’
in 2007 and in the result of which there were selected some perspective varieties: Arcadia, Victoria, Hybrid 342, Long-waited , Lora, Original.
In the world, huge work is being done to create global
information banks of plant genetic resources. The need
for conservation and rational use of genetic resources
in modern conditions has become very relevant.
Genetic collections are the basis for selection work:
creating new varieties, replenishing the assortment
with new, classic, introduced and native varieties,
adapted to the natural (soil and climatic) conditions of
the cultivation sites. In the Anapa ampelographic
collection, 4911 varieties of various ecogeographical
and genetic origin are represented, the use of which
provides great opportunities for creating and breeding
new varieties, their state testing and zoning. In the
gene pool of the ampelographic collection, most
varieties of V. vinifera L. grapes are represented by
local honeycombs of different regions of the grape
culture, and more than one fourth of varieties of V.
vinifera L. are obtained from intraspecific crossings.
Despite the value of local varieties of grapes, they do
not always meet all the requirements of production.
Therefore, to improve the local assortment, it is
necessary to carry out selection - breeding new
varieties of grapes. This article presents the long-term
results of the work on the selection of varieties of table
and technical directions in the Anapa ampelographic
collection used for breeding. Also, the role of the
genetic collection in the creation of new generation
varieties by combinative selection is shown - as
donors for creating new varieties of grapes. Dedicated
varieties are the sources of valuable traits, which are given primary importance and are especially important
for the viticulture of the Russian Federation
Effects of different levels of vitamins (thiamine, pyridoxine and nicotinic acid) and macro-elements (MS, NN and PG) on development of globular, heart- and torpedo-stage embryos and plantlets with green cotyledons and on shoot production from them were studied in grapevine interspecific hybrids: cvs. ‘Bianca’, ‘Podarok Magaracha’ and ‘Intervitis Magaracha’. Pro-embryogenic calli were derived from petiole explants on solid full-strength NN medium supplemented with different levels of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzyladenine (BA) for each cultivar and used to initiate cell suspensions in liquid NN medium supplemented with 1 mg L-1 2,4-D and 0.2 mg L-1 BA. The following formulations of media were optimal for different stages of somatic embryogenesis and for plantlets with green cotyledons development: liquid NN medium supplemented with 0.5 mg L-1 BA for globular embryo formation; liquid HTE medium (with PG macro-elements, thiamine and pyridoxine at 5 mg L-1 each and 0.5 mg L-1 nicotinic acid): supplemented with 0.2 mg L-1 BA for heart-stage embryo development, supplemented with 0.1 mg L-1 indole-3-acetic acid (IAA) and 30 mg L-1 sodium humate for torpedo-stage embryo development and supplemented with 0.5 mg L-1 gibberellic acid (GA3) for the growth of plantlets with green cotyledons. Solid MS medium modified by the addition of nicotinic acid, pyridoxine and p-aminobenzoic acid (PAB) at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.5 mg L-1 BA was best efficient for shoot production from plantlets. Inflorescence formation in regenerated plants of cv. ‘Podarok Magaracha’ grown on solid hormone-free PG medium was induced by addition of nicotinic acid, pyridoxine and PAB at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.2 mg L-1 BA into liquid modified HTE medium for growth of plantlets with green cotyledons and into solid modified MS medium for shoot production from them.
The article deals with the data of green manure crops growing on irrigated lands in the Rostov region and their impact on the yield and quality of potato of summer planting time
The article is devoted to the study of growth peculiarities of summer potato on floodplain lands of Southern Russia. High and stable yields in big farms are possible using substantiated planting time of potato which depends on specific soil – climatic conditions of the area as well as potato cultivation technology elements improvement under irrigation. The latter will provide in turn water and power resources economy. The results of field research to determine planting time allow defining the most favorable conditions for potato cultivation in the given soil-climatic zone. The analysis of data obtained on differential irrigation regimes gives a possibility to determine common regularities of irrigation standards impact on potato growth efficiency. The regime proposed is in conformity with the concept of ecological land reclamation and takes into account a moderate anthropogenic impact on landscape processes under a permissible level of summer potato productivity decrease. Therefore proposed optimal time of summer planting and rational irrigation regime will increase industrial efficiency of potato production and provide environmental safety of irrigation on floodplain lands of South Russia while allowing to economize water and power resources
A comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
