NEW MEDIUM-RIPENING WATERMELON VARIETY YUBILYAR FOR PRODUCERS IN THE SOUTH OF RUSSIA

abstract 1231609103 issue 123 pp. 1533 – 1544 30.11.2016 ru 690
At present, the demand of producers and the market determine the model of future varieties. Task for breeders is to develop varieties having a set of economic and biological traits fitting into the model templates. The developed varieties and hybrids should ensure for climatic conditions of the Krasnodar region consistently high yields, better product quality and maximum efficiency of crop industry. As a result of breeding work there was developed a watermelon variety called Yubilyar, belonging to medium-ripening group, having high figures of economically valuable traits. The variety has resistance to unfavorable factors of growing conditions and stable yields. It is suitable for cultivation in rainfed areas and practically does not require protective measures against major diseases prevalent in the southern regions. Fruits are large, of wide elliptical shape, with bright crispy red flesh and a thin crust. Determined by stable fruiting under different weather conditions, friendly yield return, commercial fruits – up to 92%. Potential yield – up to 25 t/ha. Good stored for 40-50 days, suitable for transportation on a long distance. Passed preliminary tests on the fields in the Krasnodar, Rostov regions and the Republic of North Ossetia. According to results of evaluation from producers the variety meets requirements of the market and has a commercial appeal

FASCIATION IN NATURE AND IN EXPERIMENTS

abstract 1231609120 issue 123 pp. 1786 – 1800 30.11.2016 ru 553
The phenomenon of fasciation on the example of higher plants was considered. The effect of fasciation on the various particularities of plants has been shown. The numerous examples of the different groups of plants with fasciation bodies are given. We have demonstrated that the phenomenon of fasciation is more common for cultivated plants than for wild. In most cases, fasciation is considered as an exceptional phenomenon. A number of authors have distinguished fasciation to inheritable and non-inheritable. The first is caused by internal reasons. The second is the influence of external factors such as insect damage, injury, weather conditions. The number of regularities was installed: reproductive bodies of plants fasciationing more often; thermophilic forms are more likely to be fasciation. The images of different cultures with fasciation parts are given. We discuss using the introduction of the term ”connаtions” as morphological abnormalities. Fasciation can be considered as a marker trait for the cause of this phenomenon with violation of ecological situation. The plants with morphosis, including fasciation of the certain parts of bodies, can act as indicators of environmental pollution. The study of the phenomenon of fasciation in higher plants can be regarded as a method of breeding for large fruit size. From one side, to establish the adaptation abilities of newly created genotypes. Thus, the phenomenon of fasciation has affected many areas of science. On the other side, it is proof of the violations caused by environmental factors. On the other hand, it is hereditary reasons, and can also serve as a model for studying morphogenesis

abstract 1221608010 issue 122 pp. 109 – 118 31.10.2016 ru 555
For the conservation of biodiversity, this study of patterns of biological processes and phases in the development of Convallaria majalis L. that are repeated annually becomes actual. In the article, we have presented an analysis of five years of observations of the rhythm of the development of Convallaria majalis L. in the conditions of the middle Don. There were allocated phenological phases of lily of the valley: vegetative (beginning of sprout growth, deploying of leaves), bud formation, flowering (disclosure of the first flower, mass blossoming, the withering of separate flowers, the ending of flowering), fruitage (the beginning of fruit setting, mass of fruit setting, mass ripening of fruits), the end of the vegetation (appearance of the first changes in color of leaves, the complete drying). We have defined daily average temperature and the appropriate amount of positive temperatures for the passage of various phases of development Convallaria majalis L. By the results of two growing seasons, the optimal daily average temperature for the flowering period is 14,3 ° C (the sum of average daily temperatures 161,3-204, 0С) - until 9-15 days. At higher daily air temperatures flowering begins at lower amount of positive and effective temperatures after 40-45 days after the start of the vegetation. At lower daily air temperatures flowering is longer than at higher. In the conditions of the middle Don there were allocated some examples of Convallaria majalis L. which bloom two years in a row

abstract 1211607063 issue 121 pp. 1016 – 1036 30.09.2016 ru 699
The soil by it physical and chemical properties is a poly-dispersed heterogeneous multicomponent unique environment for development of most microorganisms. The soil is the richest natural substrate according to microbial gene fund. Presence of plants and animals in soil maintains it heterogeneous as environment of soil microorganisms, which are main regulators of natural gas composition of atmosphere of Earth, including its macro- and micro-components (including the main "greenhouse" gases - methane, carbon dioxide, nitrous oxide). Recently, the elucidation of these singularities of vital activity of soil organisms has resulted in general conclusion - due to them soil cover serves as a global bio-geo-chemical membrane, through which the exchange of matter and energy between pedosphere, lithosphere, atmosphere, hydrosphere and main living inhabitants of Earth does its work

abstract 1211607076 issue 121 pp. 1207 – 1220 30.09.2016 ru 740
In FSBRI «North-Caucasus zonal scientific-research institute of horticulture and viticulture» (Krasnodar) there was carried out the comparative economicbiological study of the average-height apple-tree stock М9ЕМLA in comparison with initial weakgrowing stock М9 in manifold, nursery and garden. Manifold bushes of the clone M9ЕMLA is quite worse in force than the stock М9 and were less branchy. Output of standard per hectare of manifold at the clone M9ЕMLA was on 35,5 thousand units more, and а standard condition of cuttings - on 13,2 % higher, than at the stock М9. Cuttings of the clone were less spiked and better rooted. In the first field of nursery, the plants of the clone had a vertical growth of the central conductor, slightly weaved and were more suitable to inoculation. The output of standard plants, in the variant with the use of clone M9ЕMLA by the variety Champion, in average for 2006-2010 was on 3112 units/hа, and on the variety Prikubanskoye – correspondently on 2470 units/hа higher than grafted on the stock М9. The cost price of 1000 seedlings on the clone M9ЕMLA was on 1962 rubles less than on the stock М9, and the standard of profitability of seedling growing, on the contrary was on 14-19 % higher. In the garden the trees on the clone M9ЕMLA were worse in growth of trees grafted on М9: on volume of the crone on 0,4-0,6 m3 , in diameter of the stem on 9-12 mm, in dependence on the variety, independently on the fact that some trees on clone were more weaker than grafted on the stock М9, their productivity for 2011-2015 was higher as from one tree as from the unit of area. The intensity of fruiting expressed in yield in kilos from a tree on the unit of volume of the top of a tree on the clone M9ЕMLA was on 33-39% higher than at the trees on the stock М9
