The article analyzes the degree of introduction of phanerophytes, which form the cultural dendroflora of the northeastern part of the Greater Caucasus (Azerbaijan). The research showed that out of 115 species studied, 11 were naturalized (CH1), 71 species had good viability (CH2), 25 species had medium viability (CH3), 8 species had poor viability (CH4), resistant species (CH5 group) were not found. As a result of the research, it was concluded that woody plants that form the cultural dendroflora of the study area had a different degree of introduction in accordance with environmental requirements. The results of the study showed that for the successful introduction of the studied woody plants, planting and sowing must be carried out from different geographically productive individuals with different geno- and phenotypic characteristics in the natural habitat, taking into account the bioecological characteristics of the species and their historical past, i. e. phylogenesis. It is more expedient to collect and mobilize material.
Abstract-In research work are comparative analyzed rare and endangered trees and shrubs existed in Azerbaijan Republic natural flora, there are analyzed the factors that lead to the disappearance of the species, to the lead of species reduction and disappearance of total families, the risk categories have been identified and defined the solution ways of the problems. There are identified 6,000 species in comparative analysis of Azerbaijan flora. From them more than 1,600 species are trees and shrubs species. It is approximately 37.5% of the trees and bushes of total Azerbaijan flora. It was revealed that on the basis of monitoring 38 families, 63 genus, 188 species of trees and shrubs should be included in the category of rare and endangered species in the Azerbaijan dendroflora.They are evaluated the current protection status and recommended to be included to the "Red Book" classified by IUCN (2001) adopted categories version 3.1, by taxa classification using of APG III system. Index Terms-flora biodiversity, plant species, Caucasus region, rare and endem species
Bioecologıcal features, propagation methods root system and agrotechnics of Arabian jasmine (Jasminum sambac) which belonging to Lian group plants have been presented in the paper. The light-loving Arabian jasmine plant is grown in shaded conditions, yellowness is observed on the shoots, which leads to growth retardation have shown in results of studies. The studies were carried out in various conditions — in the shadow, on light, under the sun. In plants grown in the shade in the summer (July-August), the growth of the main shoot was not observed, compared with plants grown in direct rays in January-February, which, had growth in contrast to them, Highest results were obtained in August using green cuttings under studying of the reproduction of Jasminum sambac. No diseases have been observed in these plants, but they were susceptible to pests such as Aphidoidea, Diaspididae and Aleyrodidae during the research. Bioecological features of species, easily propagation by vegetative way, decorative appearance throughout the year allow us to use them design of interiors with plants has revealed.
The article studied and analyzed the effects of wind, light and temperature on the phanerophytes used in landscaping the Absheron Peninsula (Azerbaijan). When studying the interaction of light with the studied plants, it was found that 311 species are heliophytes, and 51 are sciophytes. The study showed that 298 species unstable to wind and 64 wind resistant. In terms of heat resistance, the studied plants were divided into 3 groups: resistant to high (54–56 °C), moderate (52 °C) and low (48–50°C) temperature. The results of the study showed that these environmental factors are crucial and make a number of changes in the dynamics of plant development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
