THE SUMMARY
CROITOR Alexandr, „Productivity of apple trees, grafted on M9, according to the
method of crown formation of ameliorated slender spindle type”, the thesis of the doctor in
agriculture, Chisinau, 2009.
Thesis includes introduction, 4 charters, conclusions and practical recommendations,
bibliography – 184 references, 10 annexes, 89 bases text pages, 2 pictures, 34 tables. The optained
results are published in 9 scientific works.
Key words: rootstock M9; apple varieties; ameliorated slender spindle; structure of
plantation; phytometric and production characteristics; yield; fruit quality; profitableness.
Domain of research: agriculture, fruit growing, 06.01.07.
Aim of research is optimization of crown structure of ameliorated svelte stem type that
assures: accelerating the process of entering the tree on economic fructification and rapid growth of
yield; early recover of capital investments; economic efficiency growth of fruit production in apple
tree superintensive orchards.
Objectives of research: elaboration of optimization methods of crown structure;
establishing high productive dimensions of apple tree crowns and plantation structure; dynamic
equilibration of processes of tree growth and fructification; rational valorization of potential of
apple tree productivity; determination of indexes optimum of main phytometric and productivity
characteristics.
Methodology of research. Theoretic support and scientific methodology of thesis have
constituted the scientific concepts of world known scientists in fruit growing domain as T.
Baldassari, J.M. Lespinasse, A. Mika, Ph. Monney, A. Sadowski. There were also studied the
scientific works of native scientists V. Babuc, V. Balan, Gh. Cimpoieş, C. Dadu, I. Donica.
Innovation and originality of research. For the first time in Republic of Moldova’s
conditions were obtained new experimental data and were elaborated recommendations for rational
structure of crown of ameliorated svelte stem type of apple tree main varieties, grafted on rootstock
M9.
Theoretical significance of research. Theoretical significance means to determine
optimum indexes of main Phytometric and production characteristics of apple trees.
Applicative value of research. Applicative value means to elaborate a new system of
rational structuring of crown of ameliorated svelte stem type in apple superintensive orchards with a
high productivity.
Practical implementation. On the basis of scientific results it was elaborated and then
implemented into production on an area of 50 ha in enterprise “Codru-ST” Ltd. city Bucovat, a new
system of rational structuring of crown of ameliorated svelte stem type in the apple superintensive
orchard with high productivity.
