OF THE UKRAINE

The researches in plants’ biology in agrocenosis and in ecological

conditions in 1978-1992 allowed to determine the zones of industrial

and consumer cherry growing in the North- Eastern r egions of the

Ukraine and to give the scientific basis to the technolagical methods

of fruit production by means of a bioclimagramma.

The researches of annual and daily biological rhythms of plants'

growth and development gave the results which allowed to determine

the turn-ware chavacter of the development of underground and

aboveground parts of a plant annually and to interpret im a different

light the mineral nouricheinent pvocess and water consumption.

There has been fomed the crown and found some advices concerning

the principle of prunning in ontogeny.

The facts gained in architectonics and root placement of some

varieties detrmined the mode of cpecing the plants up to 660 (5x3m) -

1250 (4.\2m) on a hectare and of shallow tillage within a now.

Advised have also been the grafts for a variety according to the

rind of soil in a garden block.

The biological response on physical irr itants a 1lowed to work out

themethods of accelerated growing up for transplant seedlings and

methods of seedlings adaptation to the sped fied planting places in a

garden on azimuth. The inhibiting nature of laser ray influence on

the development of the pa thogene in the "host” allowed to advise the

use of morning irradiation in fighting the coccomycosis.

The introduction of a new cherry growing technology carried out

an 40 ha in Dimitrov sovkhos of Sumy region for 8 years gave at the

plants of 1982 the 40% average yield increase compared with the

usual technologies.
