Abstract
The article presents the results of an introductory study of Korean chrysanthemum varieties in the collection of the Mangyshlak Experimental Botanical Garden. As a result of phenological observations of 26 varieties of chrysanthemum in 2018–2020, it was revealed that chrysanthemum varieties are long-growing. The duration of phenological phases is more dependent on the biological characteristics of the variety and on the meteorological factors of the year of study. During the three-year period of observations on the flowering dates in the arid conditions of Mangistau, 4 groups of chrysanthemum varieties were identified: early, middle, mediumlate, and late varieties. The total flowering duration of chrysanthemum varieties was on average from 20 to 45 days. Flowering of early varieties lasts about 25–28 days, medium and medium-late — from 35 to 45, late — about 25 days. Also, this study provides an assessment of the decorative and biological properties of chrysanthemum varieties. Through the comprehensive assessment, the most promising varieties of chrysanthemum were identified, which make it possible to create decorative floral compositions of various types in the conditions of the arid zone of Mangistau, and thereby replenish the assortment of decorative perennial plants with new varieties.
