Assessment of the ecological and biological features of the development of shrub introduced species in the conditions of the Central Black Earth Region

In the course of research, the authors analyzed the results of the introduction of shrub plants of different taxonomic groups in the conditions of the Central Black Earth Region. Most of the representatives of the collections under consideration (a collection of deciduous shrubs, a collection of ornamental shrubs, a collection of coniferous shrubs) showed significant adaptive capabilities in the conditions of the region under consideration. Recommendations on the possibility of using introduced shrubs in green urban construction are given, and species and forms that are not suitable for this purpose are identified. The authors have developed a methodology for assessing the results of introduction tests of shrub plants using the example of the Central Black Earth Region, which can be used in other regions of the Russian Federation and countries of the world to conduct similar tests. This technique is quite simple, but it allows you to create a complete picture of the adaptive capabilities of introduced species, since is based on basic indicators of plant vitality (drought resistance, winter hardiness, average annual growth, observation of flowering and seed production).

New strawberry genotypes tested for organic production on a Verticillium-infested site

Nineteen new strawberry breeding clones, bred at the Institute for Breeding Research on Fruit Crops in Dresden-Pillnitz, Germany, were evaluated for their suitability for organic production at a Verticillium-infested site in Vienna, Austria. Soil cover, plant vitality, resistance to leaf spot diseases as well as flower damages by the strawberry blossom weevil (Anthonomus rubi) and by spring frost were recorded. In two consecutive years, marketable yield and fruits infested by Botrytis cinerea were assessed. Three breeding clones, P-7189, P-8043 and P-8071, were considered as suitable for organic strawberry production. P-7189 and P-8043 showed high tolerance to Verticillium wilt. The breeding clones P-8155 and P-8166 performed well under organic management but had very soft fruits that were not acceptable for commercial fruit production. The rest of the breeding clones were low-yielding, however, some of them could be of interest for home gardens due to their good flavour and high plant vitality.  

The Plant Vitality and Air Anion Generator with its Use in Urban

Air anion and Plant Vitality is the main component of the forest environment; they play a positive role within human and nature. The Plant Vitality and Air Anion Generator which based on Lenard effects can be diffused simultaneously refined gas plants and air negative ions. Furthermore, indoor and outdoor environment can be also improved by Plant Vitality and Air Anion Generator, it has a broad application prospects on hospitals, nursing homes, urban residential areas, parks, schools, and other places.
