AGRARIAN AND BIOLOGICAL ASPECT OF INCREASE OF APPLE TREE RESISTANCE TO SUMMER PERIOD ABIOTIC STRESS-FACTORS

abstract 0621008021 issue 62 pp. 272 – 281 28.10.2010 ru 1676
Detoxication mechanism of protein deterioration products in heat resistant apple trees (Florina variety) under overheating is substantiated. Apple trees drought and heat resistance increase in non-irrigated orchard is obtained under over-row spacing turf-covering with naturally grown grasses

METHODS OF EARLY DIAGNOSIS OF APPLE-TREE RESISTANCE TO THE INCREASED PH SOIL

abstract 0861302045 issue 86 pp. 642 – 651 28.02.2013 ru 1631
In the article, there were determined the physiological parameters of resistance of stocked plants to in-creased pH soil. There was shown, that the resistance of apple-trees to the action of edafic stress-factors achieved in the case of their grafting on average-growing clone stock MM 106

REACTION OF APPLE-TREE VARIETIES AND STOCKS ON CHANGE OF pH OF SOIL

abstract 1061502045 issue 106 pp. 735 – 745 28.02.2015 ru 590
The researches are devoted to the determination of physiological parameters of grafted apple-trees joining with the level of their resistance to the change of soil рН. The experiments were carried out in the conditions of lysimetric experience with the soils use characterizing by different value of рН. The scheme of experience included the following variants of soil medium reaction: neutral (рН 7,3), typical for black soils of plain part of the region (control); weak-acid (рН 6,2) existing in soils of foothill zone of the region (grey and brown forest); strong-acid (5.1) typical for brown forest soils; weak-alkaline(рН 8.3) occurring in black soils of south and sod-carbonate soils, strong-alkaline ( рН 8.8) typical for maternal types of many black soils. There were studied the varieties of apple-trees Prima, Florina and Renet Simirenko grafted on stocks M9 and MM106 and as well as corresponding the non-grafted stocks. The reaction of grafted apple-trees on change of рН of soil is specific and depends on adaptive possibilities of grafting components: varieties and stocks. At the stock M9 we can see the active growth of shoots and roots in the meaning of pH values from 5,1 (strong-acid reaction) to 7,3 (neutral). Plants MM106 prefer neutral (pH 7,3) and weak-alkaline (pH 8,3) soils. Independently from stocks for the variety Florina the most favorable weak-acid soils and the variety Prima – mainly neutral. The variety Renet Simirenko possesses enough high and stable functional activity in the conditions of wide range of the medium reaction: from very acid to alkaline one
