In the North Caucasus there is about 50% of fruit plantations of the old type: stocks with strong and low power of growth, planting density from 320 to 416 trees/ha. The trees reach 6 feet high, the crown is thickened, minor crops and poor quality. One of the main causes of low profitability of such plantations is low intensity of pruning
In FSBRI «North-Caucasus zonal scientific-research
institute of horticulture and viticulture» (Krasnodar)
there was carried out the comparative economicbiological
study of the average-height apple-tree
stock М9ЕМLA in comparison with initial weakgrowing
stock М9 in manifold, nursery and garden.
Manifold bushes of the clone M9ЕMLA is quite
worse in force than the stock М9 and were less
branchy. Output of standard per hectare of manifold
at the clone M9ЕMLA was on 35,5 thousand units
more, and а standard condition of cuttings - on 13,2
% higher, than at the stock М9. Cuttings of the clone
were less spiked and better rooted. In the first field of
nursery, the plants of the clone had a vertical growth
of the central conductor, slightly weaved and were
more suitable to inoculation. The output of standard
plants, in the variant with the use of clone M9ЕMLA
by the variety Champion, in average for 2006-2010
was on 3112 units/hа, and on the variety Prikubanskoye
– correspondently on 2470 units/hа higher
than grafted on the stock М9. The cost price of 1000
seedlings on the clone M9ЕMLA was on 1962 rubles
less than on the stock М9, and the standard of profitability
of seedling growing, on the contrary was on
14-19 % higher. In the garden the trees on the clone
M9ЕMLA were worse in growth of trees grafted on
М9: on volume of the crone on 0,4-0,6 m3
, in diameter
of the stem on 9-12 mm, in dependence on
the variety, independently on the fact that some trees
on clone were more weaker than grafted on the stock
М9, their productivity for 2011-2015 was higher as
from one tree as from the unit of area. The intensity
of fruiting expressed in yield in kilos from a tree on
the unit of volume of the top of a tree on the clone
M9ЕMLA was on 33-39% higher than at the trees on
the stock М9
