We studied the architecture of the root system of apple tree varieties (Idared, Golden Delicious, Rei-nette Simirenko, Florina grafted on the rootstock M9), planted in 2003, according to the scheme 4 x 1 and formed by type: Russian spindle (k) Knip Baum, Bee Baum, Sollux.
We found out that on mid loamy soil with drip irri-gation, the bulk of the roots located at a depth of 10 - 60 cm regardless of the type of crown formation. Large (more than 3 mm) roots of Reinette Simirenko and Florin varieties of trees in age of seven have penetrated to a depth of 60 - 80 cm while forming Russian spindle and Knip Baum crown-type and their length and their weight was
5 – 8% of the overall performance
In the article, the results of the research of foliar nutrition of apple-tree effect on development of fruits and yield, depending on the weather condition are given. The foliar nutrition system, consisting of boro-plus and Calbit C, combined with megafol, which makes it possible to optimize fruiting in years within unfavorable weather conditions are presented
In the article, the results of research of universal method of pre-sowing treatment of seeds with a pulsed electric field, which allows them to improve crop quality and harvest by stimulating and antibacterial effects. We describe a prototype of an industrial plant for the preplant seed crops PEF pulse repetition frequency of 300 Hz to 1000 Hz.
Feasibility study of implementation of this method on the example of small innovative enterprises is shown
This article shows the vermicomposting technology in the machine of continuous operation. The article also discusses the advantages of this method
The article presents the research focuses on determining the parameters of physiological and morphological and functional features of the digestive and reproductive systems of young and laying hens under the influence of the mineral component of the
diet of local origin (ekobentokorm) in combination with biologically active substances developed and prepared by compounding (vitamin-mineral adsorption feed additive - VMAKD)
In the conditions of the North Caucasus during aflatoxin B1 tolerant level in the ration it is desirable to breed the broiler chickens cross “Smena-4” and “Ross 308” adding toxi-nyl preparation in the amount of 2 kg/t
The Dimitra variety is a hybrid, which was made as the result of Greek and Russian scientific collaboration in Greece, by Pantiley Zamanidi and Leonid Troshin in 2001 by hybridization of Aigeogritiko variety and Merlot. On its morphological characteristics it is included in the group of the Black sea varieties (convar. pontica subconvar. balcanica Negr.). The production period is 146-155 days. The leave is middle or big, black-green, five lobes, deep dissected. The middle weight of bunch is 300 g, the form is cylinder conical, middle density or friable. The berry is middle, not colored, with low labrusk taste. The yield is high. The sugariness is high. The quantity of seed in the berry is one or two. It has higher frost resistance; drought resistance and higher steadiness to mushroom diseases compare with the parents varieties. The variety is using for making desert dry red wine of outstanding quality
Using two microsatellite loci (HaSSR1, HaSSR3), the PCR analysis of the bollworm Krasnodar population was conducted. Molecular-genetic analysis (SSR-PCR) of different geographic codling moth populations by three microsatellite loci Ср1.63; Ср2.39 и Ср2.157 was conducted also. Based on the assessment of the frequencies of occurrence of DNA markers, the molecular-genetic structure was described and genetic diversity in the pest populations was estimated
The article presents three-year data on the influence of different fertilization systems and predecessors (corn for silage and peas) of winter wheat in the rotation on the dynamics of content in the 0-20 cm layer of black leached soil of mineral nitrogen, of available phosphorus, of potassium, and yield of winter wheat. The materials presented in this article indicate that, regardless of its predecessor in all phases of plant development, the under study fertilizer systems significantly increased the content of mineral nitrogen on the indicators of natural agrochemical background on 1,1-29,3 mg/kg; maximum contents was registered in the settlement system of fertilizer. After a seeded fallow predecessor the fertilizer systems significantly increased the content of available phosphorus in the soil at 1,5-16,6 mg/kg and exchangeable potassium in the 6-57 mg/kg. The maximum indices of both indicators were observed in the settlement system of fertilizer. Analyzed fertilizer systems contributed to a significant increase in wheat yield relatively to control 0,82-2,24 t/ha on a busy couple 0,74-1,6 t/ha for maize silage, 1,44-2,42 t/ha peas. Maximum productivity of winter wheat in the experiment was fixed at the fertilizer system after a busy couple, and was 6,19 t/ha
DYNAMICS OF CATALASE ACTIVITY IN THE LEAVES OF APPLE TREES UNDER THE INFLUENCE OF FOLIAR FERTILIZING
The research was conducted studying the effect of
various system of foliar fertigation on catalase activity
in the apple orchard with drip irrigation in 2013-2014.
The object of research were apple trees of
Zhigulevskoye variety grafted on rootstock 62-396 in
experimental intensive apple orchard of I.V. Michurin
FSC which had been planted in 2007. During
vegetation, the following indices were determined in
apple tree leaves in dynamics: catalase activity by
gasometrical method of M.I Lishkevich on the 3rd and
5
th day after treatments, the content of nitrogen
(Kjeldahl method), phosphorus (KFK-3), potassium
and calcium (Jenway PFP-7). Data were statistical
processed according to the generally accepted methods
described by B.A. Dospekhov. It has been established
that foliar fertigation increased catalase activity on the
3
rd day after treatment, which then decreases to normal
values. So, treatments acted as a stress factor.
Correlation of catalase activity with nitrogen content in
the leaves increased, and with calcium content
decreased as the number of megafol mixed with
calcium calbit treatments was enlarged. Using tank
mixtures for multiple treatments with combination of
antistress preparations and calcium-containing
agrochemicals allows to moderate significantly the
stress effect of foliar fertilizing on plants
