Green building, forestry, agriculture of the Rostov region is in desperate need of resistant and long-lived samples of deciduous trees of the first grade. The main object of the search of promising forms of deciduous trees were artificial plantations of Quercus robur in the Botanical Garden of SFU. The research identified several of samples of Quercus robur, which are of economic interest. Based on ecological and biological properties and economic qualities, the most promising on was a sample of Quercus robur var. tardiflora, planted in 1888. This sample is less receptive to pests and diseases. It also has a high winter hardiness and drought resistance and significantly superior to similar samples of Quercus robur along longevity and has a high decorative effect. Dedicated sample of Quercus robur var. tardiflora, and his generation from seed is very different from other samples of the population by time of phenological phases. The all main henological phases of this sample occured later by on 10-15 days. The sample belongs to the group of plants of late phenological dates start and end of the growing season. The phenology of dedicated samples contributes to their high steadiness into regional climate. It propagates by sowing freshly harvested seeds. Phenological features of the selected sample might be inherited in the seminal generations
Were summed up of perennial introductory tests of the
representatives of the family Betulaceae S.F. Gray in
the Botanical Garden SFedU. The 33 species of this
family have been studied for a total. Evaluation of
winter hardiness of the family members showed that
the absolute resistance to the full range of factors
winter have representatives genus Betula, also Alnus
incana (L.) Moench and Corylus colurna L. Species of
the genus Betula and Corylus may be attributed to the
plants having a resistance to drought. The highly
drought-resistant species – Carpinus betulus L., C.
turczaninowii Hance, Alnus incana (L.) Moench and
Ostrya carpinifolia Scop. Less than drought-resistant –
Alnus glutinosa (L.) Gaertn. Most of the tested species
should be attributed to hemixerophytes. The high
degree of defeat by fungal diseases of the species
genera Alnus, Betula and Carpinus makes them
unsuitable for the regional culture. The causative agent
of the disease is a fungus Chondrostereum purpureum
(Pers.) Pouzar. Based on the totality ecological and
biological properties only species of the genus Corylus
remain promising for the culture. For introductory test
it is advisable to attract drought-tolerant species of the
family Betulaceae such as: Alnus barbata C.A. Mey.,
A. rubra Bong., A. rugosa (Du Roi) Spreng., Carpinus
cordata Blume, C. caucasica Grossh., C. caroliniana
Walter, C. orientalis Miller., C. tschonoskii Maxim.,
Betula insignis Franch., B. lanata (Regel) V.N. Vassil.,
B. luminifera H.J.P. Winkl., B. nikoensis Koidz., B.
forrestii Hand.-Mazz., B. utilis D. Don., Ostrya
virginiana K.Koch
The article presents the average and optimal calendar dates of the main phenological phases exotic woody angiosperms in Rostov-on-Don. We assess the level of variability timing of individual phenological phases. The data obtained can be used to diagnose the prospects of exotic woody plants for the regional culture
The results of the introductory test of 22 species of the
family Caprifoliaceae from 5 genera are analyzed:
Abelia R. Br. (1 species), Diervilla Mill. (1 species),
Kolkwitzia Graebn., Lonicera L. (15 species),
Symphoricarpos Ducham. (2 species), Weigela Thunb.
(2 species) in the Botanical Garden of SFedU. The
estimation of ecological-biological properties, of
degree of naturalization is given, of phenological
development, of age status, of decorative longevity of
these species. It has been established that 17 species
have high winter hardiness: Kolkwitzia amabilis;
Lonicera caprifolium, L. coerulea, L. chrysantha, L.
demissa, L. dioica, L. ferdinandii, L. gracilipes, L. ×
heckrotii, L. japonica, L. morrowii, L. tatarica, L. ×
tellmanniana, L. trichosantha, Symphoricarpos
hesperius and S. occidentalis, Weigela praecox;
drought-resistant: Abelia × grandiflora, Kolkwitzia
amabilis; Diervilla rivularis, Lonicera acuminata, L.
caprifolium, L. confusa, L. chrysantha, L. demissa, L.
ferdinandii, L. × heckrotii, L. japonica, L. morrowii, L.
tatarica, L. × tellmanniana, L. trichosantha,
Symphoricarpos hesperius and S. occidentalis,
Weigela floribunda; medium-drought-resistant:
Lonicera coerulea, L. dioica, L. gracilipes, Weigela
praecox. Period of preservation of decorative qualities
in plant ontogeny: Abelia × grandiflora - not less than
10 years; Diervilla rivularis, Lonicera dioica, Weigela
praecox - 15-20 years; Lonicera demissa, L. gracilipes,
Weigela floribunda - 20-25 years; Lonicera acuminata,
L. caprifolium, L. coerulea, L. confuse, L. chrysantha,
L. etrusca, L. ferdinandii, L. × heckrotii, L. japonica,
L. morrowii, L. tatarica, L. × tellmanniana, species of
Symphoricarpos – 25-30 years, Kolkwitzia amabilis –
30–35 years, Lonicera trichosantha 35–40 years
