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
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
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
