Abstract
Natural populations of 5 juniper species are widespread in Crimea: Juniperus communis L., Juniperus deltoides R. P. Adams, Juniperus excelsa M.-Bieb., Juniperus foetidissima Willd., Juniperus sabina L. All of them are included in the Red Book of the Republic of Crimea. The study of the generative sphere of rare and endangered species underlies the development of measures to maintain and preserve their populations. The aim of the studies was to determine the morphological features of the berries and seeds of tree junipers of Crimea. Based on the purpose of the work, the following tasks were set: to identify the degree of heterogeneity of the berries and seeds of the studied species; to describe the structural features of female generative ones that affect the intensity of renewal of Crimean junipers. Crimean juniper species vary quite significantly in the level of development of the generative sphere. When examining the morphological features of their berries, it was found that J. deltoides is the most heterogeneous. Of particular interest is the study of the developmental features of the berries and seeds of the least common juniper in the Mountainous Crimea – J. foetidissima. If the seeds of J. deltoides and J. excelsa had a fairly thin seed coat (up to 0.61 mm), easily amenable to scarification, then the thickness of the seed coat of J. foetidissima can reach 2.8 mm, which in turn, in some cases, is more than a third of the width of the seed itself.
