We studied influence of technological methods on the yield and quality of planting stock of strawberry in a mother plantation. Features of formation of quality planting stock of strawberry of different periods of maturing are established with the three-time application of non-root top-dressing by humic fertilizer Power of life.
The results of research of technical indicators and chemical composition of feihoa fruits grown in Abkhazia conditions is presented in the article. Valuable raw material by chemical indicators with high content of vitamins, su-gars, polyphenol compounds, minerals, pec-tin is allocated from the varieties and hybrid fund. The varieties with maximum keeping quality of fruit during storage are selected for amateur and industrial cultivation
The purpose of research is to define the efficiency of a new preparation of Antifreese with a complex of biologically active agents for decrease of stressful influence on plants of weather conditions and receiving of high-quality fruits production. The conducted research allows to optimize the mode of application of Antifreeze of a Natural Origin (ANO) on sweet cherry of Kavkazskaya variety. Under the conditions of abnormally hot spring the ANO preparation used in the form of not root feeding of plants in a phase of formation of buds and blooming flowers (for 50-60 %) promoted the increase of sweet cherry ovary for 11,2-19,8 % in comparison with control variant. The increase of sweet cherry mass at 21,6 % is the other effect. This effect had a positive impact on commodity qualities of production. It is established by biochemical research that Antifreeze of Natural Origin had positive impact on accumulation of soluble solids, sugars and organic acids in the fruits, their quantity increased on 4-5%. The increase in the content of vitamin C at 16% and strengthening of color intensity of sweet cherries on 5 %, that allowed to receive fruits with high biochemical indicators of quality, was observed. The conclusion follows that Antifreeze is an additional means to correct the accumulation of antioxidants, and it has a positively affect on improvement of biological and nutritional value of fruits and their consumer qualities.
It is known that by means of growth regulators of various physiological mechanism of action it is possible to directly regulate the processes of growth and fructification of fruit crops. The purpose of research is to define the degree of influence of gibberellin treatmtnt of sweet cherrys plants on fruit ovary, the increase of their size, the maintenance of biologically active elements and trees productivity. Gibberellin was applied on Cavkazkaya sweet cherry in the Precuban fruits zone of Krasnodar Region. Object of studying of gibberellin action on sweet cherrys plants are the flowers during mass blossoming and fruits during active growth and maturing. In the period of full maturity of fruits in the laboratory of storage and processing of NCRRIH&V the content of biologically active agents is defined. It is established that trees treatment of gibberellin during formation of fruits reduces their falling and promotes to formation of full ovary. Excess of quantity of well remained and developed fruits in comparison with control is 33%. Gibberellin in all options of experience promoted the acceleration of fruits maturing of sweet cherry in comparison with control option. It is allocated as the optimum the double processing of preparation on blossoming and ovary of sweet cherry, which authentically improved the biochemical fruits indicators. This processing increased the content of P-active agents on 50,8-63,4 mg / 100g and quantity of anthocyanes (374,6 mg / 100) in the fruits of sweet cherry.
When forming the quality of strawberry berries one of important elements is the use of the fertilizers capable to protect the plants from external influences and to purposefully regulate their growth and development. In this work it is presented the results of use not root feeding by liquid complex fertilizer with micro elements of "Alga Mix B Mg" for different phases of development of strawberry plants of Onda for control of harvest formation and a chemical composition of berries. As a result of the carried out research the positive influence of the complex fertilizer on strawberry productivity is established: the number of flowers exceeded control for 2,3%, the number of developed berries - for 23% with increase in average mass of berries by 15%. It allow you to receive a harvest on 5,8 t/hectare higher. The use of not root feeding of strawberry by complex fertilizer of "Alga Mix B Mg" has allowed to improve the quality of berries: the content of soluble solids and sugars increased on 2,3%, vitamin C - on 41,1%. It is shown the improvement of tastes of strawberry berries under the influence of non root feeding due increasing in content of sugars and decrease in acidity. The strengthening of intensity of berries color connected with increase in quantity of anthocyan pigments for 13,8% favorably affects the commodity and consumer qualities of strawberry, and also the acceleration of berries maturing (for 3-4 days) demonstrates. The results of the carried out research show that by means of not root top dressing by complex fertilizer of "Alga Mix B Mg" possibly to increase in productivity, commodity qualities, nutrition and biological value of strawberry berries.
