This article presents the results of researches of study of regeneration processes of Moldova grape grafts of different thickness, at their rooting on water in optimal conditions. There were studied the main indexes of burgeon- root -formation ability of grafts; there were revealed the limits of optimal graft thickness possessing the maximum root- formation ability
PECULIARITIES OF POTENTIAL REALIZATION OF FRUIT-TREES PRODUCTIVITY IN THE YEARS OF WEATHER ANOMALIES
There was shown the influence of unfavorable climatic factors on the development of fruit cultivars. There were studied the peculiarities of potential realization of fruit trees productivity in connection with weather anomalies
The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention
Peculiarities of microсlone propagation of introduced varieties and grape clones, and home varieties created in Kuban State Agrarian University as well, which were given for national trial and for industrial production are discussed in this article.
The article presents the results of three-year researches on the study of indexes of ripening of grafts-coefficient and conditional coefficient of ripening at 9 resistant table and technical varieties of grapes and indexes of their root-formation ability when rooting in water. There was cited the analysis of presence, direction and degree of correlative connections between two studied indexes
The article presents some results of the industrial breeding of fine-wool ewes with rams of semi finewooled sheep breeds
This article deals with the results of the research work
concerning the influence of foliar application of grape
of Saperavi variety by soluble fertilizers of new
generation-Nutrivant plus and Kelik potassiumsilicon.
The influence of these fertilizers on yield and
actual fruitfulness have also been investigated. The
experiments have been carried out both in pureform
and in a tankmixture with growth regulator
“VIMPEL”. The treatment by these fertilizers has
been done three times in the following period; after
flowering, in fruit growth phase,(pea-size berry) and
in the phase of fruit maturing The foliar treatment in a
pure form as well as in a tank mixture led to increase
of bunch weight, harvest per bush and the yield
capacity of plantation. The influence of fertilizers
depended not only on variants of experiment but also
on weather conditions of the previous and current year
as well as on the previous yield. The negative
correlation between the indexes of yield structure of
the previous year and the actual fruitfulness of the
current year has been revealed. However, the character
of these correlative connections depends on many
factors and greatly differs according to the year. As a
result of these investigations, it was stated that foliar
application of Saperavi grape variety by fertilizers of a
new generation Nutrivant plus and Kelik potassiumsilicon
in a tank mixture with growth regulator
“Vimpel” in periods after flowering, berry
growth(pea-size berry) and at the beginning of berry
maturing did not promote a stable and significant
increase of the main indexes of an actual fruitfulness. The real increase observed in all experimental variants
was achieved mainly due to the increase of the
average weight of the bunch
The results of comparative analysis of three white muscat grades of grapes Viorika, the Muscat de Yaloven and the Muscat onitskan according to the biological indicators of fructification, productivity, quality of berries, mechanical structure of bunches, suitability for manufacture of direct extraction juice and dry wines are depicted in the article. All studied grades differ by high percent of fruiting runaways and high factors of fruiting and fructification. The highest factors of fruiting and fructification of runaways are reflected at grade Viorika, and the lowest - at a grade the Muscat de Yaloven. Biological indicators of fructification of runaways according to the length of a fruit spear are high and rather levelled at all grades. That is why, depending on bushes forming, it is possible to apply short and average (6-7 buds) length of vine cutting. Biological indicators of fructification of runaways from angular buds and sleeping buds are high enough, that shows to good regenerative ability of studied grades. Grades Viorika and the Muscat de Yaloven are tall, and the Muscat onitskan is average height. Degree of ripening of runaways at grades Viorika and the Muscat onitskan is good, at a grade the Muscat de Yaloven - satisfactory. Productivity of grades Viorika, Muscat de Yaloven and the Muscat onitskan is 77,94; 81,52 and 72,72 centner/hectares, and efficiency of runaway - 199,5; 193 and 221,9 with a significant difference between grades on both indicators. The exit of a mash at grades was 77,5-79,4 %. According to the contents of solids, sugars and acids, grapes of all grades correspond to requirements for manufacture of high-quality direct extraction juice. From grapes of these grades, it is possible to produce high-quality direct extraction juice under the name of ampelographic and blended grades.
Sampling estimation of dry wines from grapes of these grades fluctuates from 7,6 to 7,8 points: 7,8 (Viorika), 7,7 (the Muscat onitskan), 7,6 (the Muscat de Yaloven)
Biochemical quantitative and qualitative indices of pear fruit have been investigated in six varieties of pears grown in Prikybanskoy horticultural zone of the Krasnodar region. The investigation has been done with pear fruit in the stage of maturity for harvesting
and after 90 days after storage in refrigerator. Quantitative content of dry matter, sugars, vitamins C and P and fraction pectin content in fruits and squeezing of fruits as well as changes in the process of storage have been established
The crop productivity of peach varieties in different fruit zones of Krasnodar region was studied. The economic analysis of effectiveness of their growing was done. The practical recommendations on peach-tree gardens making were given by the results of five-year researches
