This article estimates the adaptive potential of woody plants to endure adverse weather conditions of winters 2009/10 and 2010/11. Special attention is paid to the temperature factor as a factor limiting the opportunities for introducing trees and shrubs.
This article focuses on the activity of the Volgograd regional botanical garden aimed at the creation of a collection of rare and endangered species, introduction, and the development of measures for introduction of promising species into the culture. The authors emphasize the role of seed fund in introduction studies and gene pool preservation, as well as the efficiency of cloned microreproduction of rare species.
Alongside the traditional ex situ plant conservation methods, the creation of gene banks in vitro is increasing in importance. The research and methodological framework for the creation and conservation of rare and valuable plant seed and meristem gene banks is being developed. In the creation of gene banks, special attention is paid to plant species representativeness and genetic stability preservation. Most of the plant material is stored in conditions of decelerated growth.
This article focuses on the activity aimed at registering of the populations of rare and endangered plant species in the Volgograd. The authors address the legal and methodological framework for this process and present the results of the work conducted.
The biological parameters of environment, such as the period of phenological phenomena, tree-rings, and physiological reactions in plants react to external and internal changes in the conditions of growth that can be used as indicators of the environment, its condition and changes. This article identifies the differences in the thermodynamic reactions of trees growing in areas with different seismicity.
The accumulation of green mass in annual long day plants was studied in different climatic conditions (northern Kazakhstan and the Kaliningrad region).
