The article reviews the results of the study of influence of treatment of Saperavi vines with growth promoters (Immunotsitofit, Krezatcina and HB-101ECO) on its productivity and quality in the Anapо-Taman zone of the Krasnodar region
The article presents experimental data on the research
of gold nanoparticles (GNPs) with mean diameter 15
nm and 50 nm effect on seeds germination and growth
of 3-day-old etiolated coleoptiles and roots. Compared
with distilled water (control) initial colloidal solution
of 15 nm and 50 nm GNPs (57 µg/ml) had no
significant impact on seeds germination and growth of
coleoptiles and roots. However, in both cases a weak
tendency to stimulation of the coleoptile growth and
root growth inhibition was observed. Reduction of 15
nm GNPs concentration down to 10 µg/ml and 1
µg/ml had not effect on the growth of the seedlings,
but stimulated seed germination up to twofold.
Similar concentrations of 50 nm GNPs exerted the
stimulating effect on seed germination (twofold) and
the growth of root and coleoptiles. Seedlings grew
especially intensive in colloidal GNPs solution with
Au concentration of 10 µg/ml. Temperature rise of 2
degrees (from 25°C to 27°C) resulted in growth
increase of control 3-day-old seedlings and opposite
effect of 50 nm GNPs: coleoptiles and roots growth
fell behind control seedlings growth by 16-17%.
However, on the 4th day, the relative growth
slowdown of control seedlings occurred at 27°C and
growth stimulation effect under the influence of 50
nm GNPs appeared again. Over time, the stimulating
effect of 50 nm GNPs decreased: at the end of October it weakened, and in November – beginning of
December, it was no observed for the roots, and there
was a decline in coleoptiles growth. However, in all
cases the effect of stimulation of seeds germination
persisted under the influence of 50 nm GNPs,
weakening by December. We hypothesize the
molecular mechanisms of biological action of GNPs
It was established that water absorption of soybean seeds does not depend on the variety. And in the beginning it has an active character, providing the increase in mass of seeds on 80-140% after 12-14 hours. Subsequently, hydration intensity decreases
and mass reaches 110-160% of the original. Electroactivated water increases the level of hydration in comparison with tap water (anolyte – 10-18%, catholyte – 5-9%). Furthermore, in the process of germination of soybean protein content increased by 4-12% and fat – 7-16%. Inhibitor content thus decreases by the same amount, and does not depend on the variety. Thus, consideration of the varietal characteristics of soybean seeds during germination allows how to reduce energy consumption for processing and to reduce the degree of destruction of nutrients
The key stage of clonal micropropagation, the micropropagation sensu stricto, affords to increase the propagation index for plants, especially perennials. In this study, we consider ways to optimize clonal micropropagation of remontant raspberry cultivars. It is found that microsprout regeneration rate is 78,5–96,0 % on the multiplication s. str. stage. The most multipurpose nutrient medium is selected with containing 0,5 mg/l both of BAP and GK. When one uses this medium, regeneration rate runs 79,0–94,0% depending on genotype with sprout high running 24,8–32,7 mm and sprout number – 1,2–2,2 per node. The optimal duration of growing cycle is 30 days with the propagation index within 6,6–7,8, depending of genotype
Physical processes, arising up at removing of rock from the backwall of mining hole, are considered. The curve of sedimentation, allowing to determine the rate of climb of transporting of rock at cleaning of back-wall with newtonian liquids – air and water, is shown. The formula is shown out for the calculation of ex-pense of borax solution, necessary for the high-quality cleaning of backwall of mining hole at washing water or air
The author has studied the efficiency of diets with NATUPHOS 5000 enzyme preparation. Adding the enzyme preparation into the mixed fodder for chicken broilers favors increase of live weight by 4,5 % and average daily weight gain by 6,1 %
An experiment was conducted to examine the effect
of fatty acid concentrate (FAC), as a new source of
energy and carnitine on performance, physiological
condition and meat quality of broiler chickens. In
experiment there were four groups of 80 chickens of
cross Hubbard each (males: females=40:40) in age
period 0-41 days. 1 group (control) received in during
the periods 0-14, 15-28 and 29-41days, sunflower oil
(SO) respectively 5.34%, 5.50%, and 6.10%, group 2
received the same amounts of FAC instead SO, 3
group - mixture SO:FAC (50:50), 4 group -FAC +
0,25% carnitine. Final body weight: 1 group =
2574±29 g, 2 group FAC= 2553±27 g 3 group SO +
FAC = 2531±34 g., 4 group FAC+0,25 carnitine =
2520±34 g. Feed conversion, digestibility of
nutrients, blood hematology and biochemistry, the
condition of organs, meat quality and cutting of
carcass of chickens on FAC had no any differences
from the same signs in chicks on SO. Carnitine had a
positive effect on chicken growth only in the period
0-14 and less 15-28 days; in the period 29-41 days
daily gain was below, than that in 1-3 groups.
Canitine reduced the content of liver fat. Outcome:
FAC is a satisfactory source of energy, comparable
with vegetable oils. The price of FAC is 30% lower
in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of
vegetable oils will be of great economic importance
The author has studied the efficiency of diets with
kiselgura. Introduction of the kiselgura into the mixed
fodder for chicken-broilers favors increasing of live
weight by 4.8 % and average daily weight gain by 5.0%
