REGENERATIVE PROPERTIES OF GRAPE CUTTINGS UNDER THE INFLUENCE OF TREATMENT WITH IAA
06.00.00 Agricultural sciences
DescriptionThe article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings

FERTILIZING OF A WINTER WHEAT SOWN AFTER WINTER WHEAT AND COMMON SAINFOIN ON ORDINARY BLACK SOIL
06.00.00 Agricultural sciences
DescriptionDistinctions of soil under a winter wheat after a winter wheat and common sainfoin in provision of moisture and feed elements are revealed. Influence of autumn application of complete fertilizer and spring nitric dosage compensations on productivity and quality of a winter wheat are established; dependence of fertilizers’ effect from nitrate nitrogen contents in the soil is shown. Optimum dozes combinations on both predecessors are found

DescriptionThe introgression of race-specific blast resistance genes Pi-ta, Pi-b, Pi-z into genotype of Russian rice variety has been performed by backcross method with marker control of donor alleles. Plants that demonstrated maximal similarity with recurrent parental form, the short vegetation period and abundant panicle fertility have been picked up from BC3-population. Marker analysis of developed population revealed the samples carrying introduced target genes in homozygote state

DYNAMICS OF ENZYME’S ACTIVITY OF BLACK SOIL WHEN POLLUTING WITH ANTIBIOTICS
06.00.00 Agricultural sciences
DescriptionIn the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character
