According to the results of long-term evaluation of promising hybrids of lavender angustifolia the ability to predict the influence of abiotic factors on the yield and gathering of essential oil of inflorescences is shown. Correlations, agronomic stability and variability of the yield of hybrids are defined
The results of development of rice breeding lines, carrying the wide range resistance gene to rice blast disease - Pi-40. For identification of the dominant allele of the gene the DNA - marker analysis was used. With co-dominant DNA markers plants from inbred populations that carry a dominant allele of this gene in the homozygous state were selected
The stage of introduction of plantlets to in vitro
culture is an important stage of technology of
clonal micropropagation of plants. For the
purpose of decrease in a share of the plantlets that
were lost from an infection and increase of their
regeneration ability, sterilizers and antibiotics,
effective and safe for apple rootstocks’ plantlets
wee allocated, and also favorable terms of
introduction to in vitro culture were allocated. As
a result of the conducted researches, we have
established that on influence on an nutrient
medium and plantlets infection and on growth and
development of plants, beneficial effect on apple
rootstocks’ plantlets has an antibiotic nystatin of
200 mg/l: the reproduction coefficient on the
medium with this antibiotic is equal 4,3, in the
same concentration nystatin has the sanifying
effect of 60-75% for stocks of SK 2 and MM 106.
During researches of sterilizers for apple
rootstocks’ plantlets SK 2, SK 3, SK 4, SK 7,
MM 106 as an alternative to widely applied
highly toxic sterilizer corrosive sublimate (the
first class of danger) were picked up effective and
safe preparations for sanitation of plantlets from
an infection, such as the household preparation
"Whiteness" (sodium hypochlorite) in cultivation
1:2, low-dangerous substance of the fourth class
of danger (a share of viable plantlets of 75,5%
from initially introduced), and also fosfopag, a
preparation of the fourth class of danger (a share
of viable plantlets of 65% from initially
introduced). The favorable term for a meristem of
apple rootstocks’ plantlets’ introduction to in vitro
culture are phases of buds’ burgeoning (March)
and the intensive growth of shoots (May – June)
In the present article, we have described data of comparative ampelography of biometric evaluation of leaf parameters of the three table grapes: Preobragenie, Victor and Jubiley Novocherkassk, widespread in the amateur and farming areas of Russia and the Ukraine. Showed results of molecular genetic analysis of DNA from these table grapes
The article presents the results of studies of the influence of fertilizers on plants height and accumulation of the biomass of alfalfa
The article presents the data of many years of research
on resilience, durability and natural renewability of
forest park plantations on sand and shell soils of the
Eastern Azov
Remineralization of leached black soil was carried out by making such rocks as loess-like loam, shell limestone, apatite phosphogypsum. It was revealed, that the introduction of species did not change substantially the content of boron during the growing season. The manganese content in relation to the control increased by 13-15%, 25-30% for copper, zinc, 35-45%, 25-30% cobalt, and molybdenum in 2-3 times, and especially when combined application of rock. Seasonal dynamics was expressed, but does not give definite pattern
This article shows the lines for the processing of manure. Besides, the equipment which is necessary for the realization of the process is defined
This article presents the results of genotyping of new
perspective table and technical varieties and grapes
protoclones. It was established that varieties of Citrine,
Helios, Arcadia pink and Preobragenie show differ
genetic diversity in four loci
In this article, the results of the research of quality
characteristics of Russian rice varieties were observed
