COMPARATIVE ANALYSIS OF FORMS OF SOME TYPES OF CHERRY (CERASUS L.) FROM VARIOUS ZONES OF THE AREA

Abstract

This article, as the subject of research, compared the observed structural features of perennial stems of two wild cherry species (Cerasus alaica Pojark., C. mahaleb (L.) Miil), growing in different zones of southern part of Kyrgyzstan. The purpose of the work is to determine the structural features of the long-term flow of forms of studied species found in different conditions, and the features of their adaptation to environment. The research method is comparative anatomical. The structures of the stem structure of the forms C. mahaleb and C. alaica are common, found in different regions, consist of the same elements (vessels, tracheids, parenchyma, libriform fibers) and have a structure characteristic of each species. It was noted that the observed difference in the structure of the perennial stem of the studied forms was only quantitative in nature, and the conservatism of the general structure of the perennial stem was also noted and confirmed.The forms of C. mahaleb grown in nurseries in the form of cuttings in the Kadamzhai region differ from the form taken from the natural conditions of the Uzgen region, and the indicators of the stem elements are characteristic of organisms living in favorable conditions C. alaica was taken from the Nookat region. In comparison with the characteristics of the alayka form, it is clear that the characteristics of the forms taken from the pool of Gulche River and trees growing around the city of Osh were formed due to the unfavorable influence of environmental factors.
