Исследование совместимости привойно-подвойных комбинаций абрикоса с использованием биохимических показателей

Abstract

Results of long-term of field and biochemical researches on studying of compatibility of the apricot with clonal rootstocks are presented. It is shown, that in conditions of the Moscow area development of plants and their state depend on the degree of compatibility scion/stock combinations. Reduction of trees longevity of combinations of varieties ‘Alesha’ and ‘Samarskiy’on SVG-11-19 is marked. Incompatibility of apricot with the stock SVG-11-19 had a slowed down nature and was manifested in the form of fractures at the place of inoculation in the garden at the age of 1-6 years. In laboratory conditions it is established high antioxidant activity of leaves and bark at well compatible combinations (varieties ‘Alesha’ and ‘Samarskiy’ on stock OD-2-3). It is marked reduction of this parameter on 20 % at scion/stock combinations with insufficient compatibility (varieties ‘Alesha’ and ‘Samarskiy’ on stock SVG-11-19). Differences on antioxidant activity of leaves during active growth of plants have been expressed more strongly, than at research of bark in the beginning of vegetation. The effect of rootstock on the qualitative composition of secondary metabolites of leaves was established by the method of high-performance liquid chromatography, as evidenced by differences in the chromatographic profiles of alcohol extracts of the leaves of the studied varieties. With the help of electronic microscopy anomalies in regeneration and differentiations of fabrics in zone of accretion at incompatible combinations of apricot were revealed.
