Summary

The thesis is presented on 123 printed pages and consists of: introduction, 4 chapters, conclusions and recommendations for production, bibliography of 195 titles. Illustrative material includes 32 tables, 21 figures, 2 appendices. The results are published in 11 scientific papers. Keywords: quality fruit, forms of crown; level of profitability, intensive planting, harvest, apple varieties, planting structure. Fields of study: agriculture, fruit growing, 06.01.07. Scope of work is to increase productivity of intensive apple plantations in two oblique planes and economic efficiency of fruit production through agro biological and economic reasoning to the most appropriate forms of crown for their establishment. Main objectives of the scientific paper: the study of bioconstructive parameters of trees and basic photometric characteristics of structure of plantation depending on the variety and the constitution of the oblique plans, assessing fructification trees depending on variety and type of crown used at the establishment of oblique plans; apple orchard economic evaluation depending on variety and type of crown. Scientific novelty and originality. Pentru prima dată în condiţiile Republicii Moldova s-au obţinut date experimentale noi despre creşterea şi fructificarea pomilor de măr conduşi după formele de coroană folosite la constituirea planurilor oblice ale coronamentului. S-a argumentat din punct de vedere agrobiologic şi economic cea mai adecvată formă de coroană pentru plantaţiile intensive de măr cu coronamentul în două planuri oblice. For the first time in the Republic of Moldova there have been obtained new experimental data on growth and fructification of apple trees leaded by the type of crown used at the establishment oblique plans of the crown. It was argued in economic and agro-biological terms the most appropriate form of crown for intensive apple plantations in two oblique planes. Important scientific problem is solved in fruit growing in improving the structure of intensive apple plantation canopy in two planes oblique crown form of argument for their establishment. Theoretical significance of scientific paper. Theoretical significance of the work is to complete scientific necessary database to optimize the structure of fruit plantations. Practical value of scientific paper. The practical value of work paper the recommendation for froduction to form the crown in two oblique planes in intensive apple tree orchard plantations from free flat palmeta crown having an angle of branches to 75-800 from the horizontal position Implementation of scientific results. The main results of investigations were presented and approved at 5international scientific symposia (Chisinau - 2007, 2008, 2010, Volgograd - 2008, Iasi - 2011), republican and regional practical seminars in the field. The results of scientific research were implemented on an area of 1,3 ha at DES "Criuleni”.
