The comparative analysis of the condition of green plantings of the city of Voronezh is carried out. The objective differences in the pathogenesis of native and introduced species of forest plants are identified
The article discusses the features of the pathogenesis of micromycetes Gibellina cerealis Pass. on winter wheat
This article summarizes the results of the study of physical, chemical and biological characteristics of mineral waste; it analyzes the specific features of its behavior when applied to the soil in pure form and in complex compost; the possibility of using some of them as an ameliorant for improving the fertility of soil common in the steppe zone of the region
We know, that in the development of the natural ecosystems of the Western Priazovye its biomass predominates. This ensures the maximum protection from noticeable changes of habitat. Basic succession defining a significant shift of energy flow in the direction to increase of their expenditures to maintain forming populations determined by broad specialization of natural systems on ecological niches, and their individuals have rather small size, the life cycles of many of them are very simple and short. The coastal strip of the Azov Sea has been seriously degraded due to powerful recreational load, especially in the summer. Presumably one should expect an increased anthropogenic load on ecosystems of this area. Quite obvious is a regularity of overload agroecosystem which occupies the territory between the river and other water formations. The relatively low productivity of agricultural systems of the Eastern Azov is limited by number of factors, among which the main place is occupied with the moisture, nutrients and high weediness of sown areas
The article discusses the features of the accumulation of essential oil in the collection samples of Oregano studied in the foothill zone of the Crimea. The range of variability of the mass fraction of essential oil of Origanum vulgare (from trace amounts to 0.53% of the bone dry weight). We have revealed that the greatest
amount of essential oil accumulates in the inflorescences during the flowering phase
The phenomenon of fasciation on the example of higher
plants was considered. The effect of fasciation on the
various particularities of plants has been shown. The
numerous examples of the different groups of plants with
fasciation bodies are given. We have demonstrated that
the phenomenon of fasciation is more common for
cultivated plants than for wild. In most cases, fasciation
is considered as an exceptional phenomenon. A number
of authors have distinguished fasciation to inheritable
and non-inheritable. The first is caused by internal
reasons. The second is the influence of external factors
such as insect damage, injury, weather conditions. The
number of regularities was installed: reproductive bodies
of plants fasciationing more often; thermophilic forms
are more likely to be fasciation. The images of different
cultures with fasciation parts are given. We discuss using
the introduction of the term ”connаtions” as
morphological abnormalities. Fasciation can be
considered as a marker trait for the cause of this
phenomenon with violation of ecological situation. The
plants with morphosis, including fasciation of the certain
parts of bodies, can act as indicators of environmental
pollution. The study of the phenomenon of fasciation in
higher plants can be regarded as a method of breeding for
large fruit size. From one side, to establish the adaptation
abilities of newly created genotypes. Thus, the
phenomenon of fasciation has affected many areas of
science. On the other side, it is proof of the violations
caused by environmental factors. On the other hand, it is
hereditary reasons, and can also serve as a model for
studying morphogenesis
