Characteristic of chemical composition of varieties of grape cultivated in the Central zone of Krasnodar region and quality of juice produced from them is given in the article. Varieties for manufacturing of high-quality juices are recommended
Considered review of Krasnodar region scientists: professor Sheudzen A. H. (RI of rice), professor Zamotailov A. S., professor Doroshenko T.N., (Kuban States Agrarian University), professor Kobzar V. F. (RI of Biological plant protection), professor Goleekov V. I. (Kuban States University) on the book “Bacterial disease of cultivated plants”, issued by Kuban States Agrarian University in 2008
Effects of different levels of vitamins (thiamine, pyridoxine and nicotinic acid) and macro-elements (MS, NN and PG) on development of globular, heart- and torpedo-stage embryos and plantlets with green cotyledons and on shoot production from them were studied in grapevine interspecific hybrids: cvs. ‘Bianca’, ‘Podarok Magaracha’ and ‘Intervitis Magaracha’. Pro-embryogenic calli were derived from petiole explants on solid full-strength NN medium supplemented with different levels of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzyladenine (BA) for each cultivar and used to initiate cell suspensions in liquid NN medium supplemented with 1 mg L-1 2,4-D and 0.2 mg L-1 BA. The following formulations of media were optimal for different stages of somatic embryogenesis and for plantlets with green cotyledons development: liquid NN medium supplemented with 0.5 mg L-1 BA for globular embryo formation; liquid HTE medium (with PG macro-elements, thiamine and pyridoxine at 5 mg L-1 each and 0.5 mg L-1 nicotinic acid): supplemented with 0.2 mg L-1 BA for heart-stage embryo development, supplemented with 0.1 mg L-1 indole-3-acetic acid (IAA) and 30 mg L-1 sodium humate for torpedo-stage embryo development and supplemented with 0.5 mg L-1 gibberellic acid (GA3) for the growth of plantlets with green cotyledons. Solid MS medium modified by the addition of nicotinic acid, pyridoxine and p-aminobenzoic acid (PAB) at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.5 mg L-1 BA was best efficient for shoot production from plantlets. Inflorescence formation in regenerated plants of cv. ‘Podarok Magaracha’ grown on solid hormone-free PG medium was induced by addition of nicotinic acid, pyridoxine and PAB at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.2 mg L-1 BA into liquid modified HTE medium for growth of plantlets with green cotyledons and into solid modified MS medium for shoot production from them.
The Makedonas is a new wine higher quality black grape’s variety, was found out by Panteley Zamanidi and Leonid Troshin in 2001 in Greece and created by hybridization between Ksinomavro and Cabernet Sauvignon varieties. It’s belong to the group of Black see pool varieties on morphologic-physiological characteristics (convar. pontica subconvar. balcanica Negr.). The variety is used for making dry red wines of excellent quality. It is very perspective variety in Southern zones of Europe where the grape couldn’t get good acidity in the juice of berries
The historical review of productive and economic position in grain and beet-root branches of agrarian and industrial complex of the Russian Federation from 1990 for 2008 is carried out. Methodological and productive and economic aspects of the developed system of the organization and management of harvest-procuring of a grain yield and sugar beet, and a problem of interdepartmental interaction are analyzed. The innovative approach to increase of efficiency of harvest-procuring in plant growing in modern conditions is offered

Models of model trees in the manner of equations for calculation of the current increase of trees at radius in cedar, mixed fir and pine plantings are received. At calculation of the current increase at radius and height using the diameter of a tree on height bosom without cortex, age tree and average distance from nearest tree on radius is recommended.
The article shows the results of the impact of foliar nutrition on crop and product quality of the Grenny Smith apples. Also the impact of the agricultural practices to fruits saving ability is discussed, as well as their quality in terms of sugars, acids and vitamin C. It was found that the use of 3-fold foliar nutrition feeding with nitroammofoska impacts positively on the results of storage.
It was being done to established difference by sus¬cep-tibility rate of plant pathological bacteria Pse¬udo¬monas syringae spp. It was clearly recog¬nize, that are cultivating varieties Zimtra and Nota were the most susceptibility, and, Krasnodarskaya 99, Fortuna, Pamyat, Batko, Tania were low resis¬tance. Usage for sowing high affected seeds by Pseudo¬monas syringae spp. Leads to decreasing its germi¬nation and biometrical parameters of young growth.
