Abstract

The relevance of research on the study of the characteristics of fruiting groups of nut-bearing associated with the increasing demand for their fruits and reducing the area of natural growth of these plants. Members of the genus Corylus L. are economically important plants. Analysis of the literature on the experience of the introduction of species of the genus Corylus L. in different parts of Russia, allowed to establish limiting factors for growth. In southern regions, plant development C. avellana, C. heterophyllous limit high summer temperatures and deficiency of moisture. In the Northern regions, the growth and development of C. pontica, C. colurna is influenced by low winter temperatures (below -30°C). The data on the modern area of Corylus avellana and raw stock of fruits of all Corylus species are given.


The goal is to analyze the geographical distribution of the genus Corylus L. proclamations and their seasonal patterns of fruiting.


In the natural dendroflora of the Volgograd region species of the genus Corylus L. do not grow, but are of scientific and practical interest to work on their introduction.


Experimental data on fruiting species and varietal diversity of the genus Corylus L., which grows in the dendrocollections of the FNC Agroecology RAS, in chestnut (cadastre. № 34:36:0000:14:0178), light-chestnut soils (№34:34:000000:122; №34:34:060061:10), southern chernozems (Novoanninskiy district of the Volgograd region).


A comparative assessment of life forms and state of Corylus L. in the natural habitat and research area (Volgograd region) is given. The dynamics of the main phenological seasons in different natural zones of the Russian Federation, where the natural range of species of hazel is. The conjugacy of phenophases with seasonal rhythm of climatic parameters and the most important phenophases with each other is established. Spatially-geographical, interannual temporal phenological patterns of development to predict the potential fruit productivity of the species and varieties of nut-bearing shrubs.
