The purpose of research was studying of the commodity qualities and chemical composition of apple-tree fruits of late maturing introduced varieties and varieties of Institute breeding which are grown up under the conditions of the South of Russia. It is noted that the special importance have the questions of improvement of vitamin provision of the population due to consumption of the fruits with the high content of ascorbic acid. In research there were 10 apples varieties, among which 4 varieties of NRRIH&V (Kubanskoe Bagryanoe, Prikubanskoye, Margo, Orphey). The research of indicators of fruit's chemical composition were carrying out using the standard techniques. Data on the content of soluble solids, sugars, acids and vitamins in the fruits of studied apple-tree's varieties are presented in this article. It is established that Granny Smit (220 g) and Prikubanskoye (205 g) apple varieties have the maximum mass of a fruit. The high content of soluble solids is typical for varieties of Institute breeding of Margo (14,0%), Orphey (15,5%), and also for the introduced Champion's variety (14,0%). The fruits of these varieties have also the high accumulation of sugars: the general content of sugars in 1,3 times higher than at the zoned Idared's variety. The highest amount of fructose (5,4%) and the minimum quantity of sucrose are noted in the apples of Margo of Institute breeding, that allow you to allocate Margo apple-tree in a group of the varieties possessing the valuable treatment-and-prophylactic qualities. The total content of pectin in the apples of the studied apple varieties was above a control sample. On the sum of pectin substances an apple-tree of Prikubanskoye with content of 0,5% of soluble pectin and 0,55% of protopectin was picked out.
The recent years nalysis of intensive horticulture development of the south of Russia is given in the article. The influence of stressful weather factors on yield and commodity quality of fruits is studied. Basic agrotechnological methods that have influence on formation of productivity of fruit plants are analyzed.
The estimation of productivity and fruits quality of the apples elite forms of NCSRIMFG breeding is given. The hybrid forms with high productivity and fruits quality, with the genome of resistance to scab are allocated and recommended for breeding and expansion of the apple regional assortment.
The comparative evaluation of the chemical composition and the technical indicators of Vasilisa cherry fruits grown in the Krasnodar region and depending on the crown formation is presented. The Fogel and Stop-Leader formations permitting to obtain the fruits with high content of dry matters, sugars and vitamins are allocated.
The purpose of the carried out research is development of a way of a formation of sweet cherry trees on a high growing rootstock at high density of plants landing (5,0 x 2,0m). Research are carried out under the soil climatic conditions of LLC "Interinvest", of Stavropol Region. Objects of research are the sweet cherry varieties of various ecological-geographical origin: Zemfira, General-skaya, Donetskiy Ugolyok. The results of research allowing to recommend the new system of pruning of sweet cherry trees on strongly growing rootstock are presented in this article. At this system the low-trunk skeleton of crown with vertically growing the same branches is formed. Periodic rejuvenation of these branches will promote the formation in a crown of young flexible branches (5-6 years). It allows you to carry out the harvesting of sweet cherry fruits without garden ladders and it increases in labor productivity. Use of a strongly growing rootstock stimulates the rapid growth of vertically focused branches in a crown of trees, increases in intensity of process of generative buds formation and accelerates the plants introduction in fructification that gives the chance of getting of industrial harvest of sweet cherry fruits for 2-3 year after laying of branches. It is noted that when increase in stressful influences during cultivation (a heat, a drought, hot dry winds, the frosts) the new system of formation of sweet cherry trees on a strongly growing rootstock in the gardens of intensive type increases in resistance of plants to influence of stressful factors of the environment. When forming a harvest of sweet cherry fruits on the vertical highly growing branches during the early-spring periods of vegetation the decrease in harvest loss from frosts, and also from a hail that more damages the horizontal branches of trees is reached.
