EFFECT OF MECHANICAL AND CHEMICAL PREPARATION OF ABIES ON POTATO (SOLАNUM TUBEROSUM L.) MORPHOGENESIS IN COURSE OF MICROPROPAGATION IN VITRO

abstract 1301706046 issue 130 pp. 670 – 679 30.06.2017 ru 697
The article gives the results of the study of an effect of mechanochemical powder of wood green of Abies (MPA) on potato morphogenesis in vitro. The study involved the hormone-free nutrient mediums (MS, ½ B5, ½ LS) for growing microcuttings from preliminary obtained aseptic plants. Plant morphogenesis was observed on the 15th and 30th days. At that, the number of developed shoots, plant height, leaves number, rhizogenesis rates, root number and length were estimated. MPA appeared to have the regulatory effect on morphogenesis of potato microcuttings. Based on mineral composition of the nutrient agar medium for potato microcuttings growing, MPA at 100 mg/l concentration induced root development (½ B5 medium), reduced height of shoots (MS medium), while the number of leaf blades was not affected

PRODUCTIVITY AND METABOLISM IN DAIRY COWS WHEN FED WITH HERBS COLLECTION IN THE CONDITIONS OF YAKUTIA

abstract 1201606092 issue 120 pp. 1378 – 1391 30.06.2016 ru 391
Feeding lactating dairy cows of the Simmental breed using the collection of herbs with Тhyмus bituminosus Klok, Achillea millefolium L., Polygonum aviculare L., Galium verum L, Chamerion angustifolium L., Sanguisórba officinális, Stellaria media L. and Amaranthus retraflexus L. contributed to a better digestibility and nutrient utilization of diets. A high level of digestibility by cows experimental compared to the control group is set with respect to the dry and organic matter of 2.0% and a crude protein 1.4 %. When using the collection of herbs, there was an increase in the antioxidant status of erythrocyte cells in blood of dairy cows as expressed in the increasing content of low molecular weight antioxidants in blood cells by 1.4 times in reducing the intensity of lipid peroxidation of erythrocyte membranes in 1,2 times, in comparison with the control values. The use of the collection of herbal increases milk yield of cows of the experimental group by 7.4 %, increases by the 16.2 % yield of milk fat and the protein content of 10.7 % in milk of dairy cows compared to the control group

RESOURCE POTENTIAL IN LUTEOLIN-7- GLYCOSIDE VERONICA INCANA (SCROPHULARIACEAE) IN CENTRAL YAKUTIA

abstract 1201606091 issue 120 pp. 1364 – 1377 30.06.2016 ru 645
The article reveals luteolin-7-glucoside accumulation in the overground part of Veronica incana L. It assesses resource potential of V. incana depending on the phytocenotic conditions of coenopopulations growing in Central Yakutia. Collection of the material was carried out during V. incana flowering in 7 coenopopulations and in the collection of the Yakut Botanical Garden. Analysis of flavonoids content was performed by HPLC method. The high levels of flavonoids content in the biomass of generative plants marked in coenopopulations that are in optimal conditions, and the lowest - in coenopopulations experiencing strong anthropogenic influence. In addition, one of the factors reducing the content of flavonoids in plants is low light intensity in habitat. The highest resource potential on the luteolin-7- glucoside observed in biomass V. incana, growing in fescue grassland steppe and culture
