Assessment of the perspectivity of introduction of woody plants in the arid conditions of Mangystau

Abstract

The introductory study and identification of promising and sustainable taxa of woody plants is important for green construction and ornamental gardening of Kazakhstan. It is important to choose sustainable crops for arid conditions characterized by extreme conditions and deficient woody plants of local flora. This article presents data on the study of the rhythms of seasonal growth and plant development. There are differences that are expressed in changing the timing of the onset of vegetation (5–10 days), flowering and fruiting (15– 20 days) and reducing their duration. In the arid conditions of Mangyshlak, according to the vegetation dates, there was an increase in plant prospects for phenogroups from PP (previously the beginning and earlier the end of vegetation) to PП (previously the beginning and later the end of vegetation), a decline in СР (the middle beginning and earlier the end of vegetation) and an increase in СС (the middle beginning and the middle end of vegetation). From the 183 introduced plants 52 taxa belong to the first perspective group (high), 95 taxa — to the second group (elevated), 34 taxa — to the third (medium) and 2 taxa — to the fourth (low) of the selected 6 pheno groups. These data indicate the success of the introduction and the prospects for their further use. An electronic database on collectible woody plants is being formed on the computer program «DInCeR,» developed by the Mangyshlak Experimental Botanical Garden.
