Fruit growing
and viticulture of South Russia
Breeding and production of planting material
The nomenclature and short description of indexes characterized the nursery gardening production quality in accordance with basic object quality metering requirements for normative documents working out defining production process as well as fixing requirements to final production quality have been given.
Full information about the program of orchards nursery development in the south of Russia on 2013-2015 is given.
In the article the results of the strawberries vegetative reproduction in the two soil-and-climatic zones are given: in the Krasnodar region and Belarus.
The results of study of paraffin mixes, with different concentrations of plant growth regulators using, before stratification of grafted grapes cuttings is given. The most cost-effective and least resource-saving versions are determined.
The use for grafting of rootstocks of "super-standard" category can serve as the promising technique of cultivation of fruit crops seedlings. The influence of SC-3, SC-4, SC-2, MM106 rootstocks on the development of annual apple seedlings of Renet Simirenko, Fuji, Liberty varieties is researched. The dependence of the quality of seedlings, grown by budding, from the thickness of the stock is revealed. It is established that increasing the thickness of rootstocks used for growing seedlings of all experimental varieties, is accompanied by growth characteristics such as height and trunk diameter of seedlings, number of branches and length of branches. Of these, the diameter of the trunk, the number and length of branches are the defining characteristics of seedlings capable to harvest in the first year after planting. The diameter of the stock has the biggest influence on a number of branches (46,0 %) and their length (46,2 %) the lesser influence it has on diameter of the trunk (37,6 %), the height of the trunk (29,5 %) and the height of the seedling (29,2 %). Based on these results, a parametric model of quality improvement of dwarf fruit seedlings on the rootstocks of "super-standard" category is elaborated. This model is the discriminant function.
