Application of Allium Hirtifolium for the Selection Process in Architecture and Environmental Sciences

Abstract

Contrary to the popular belief, green space is not just a plant-covered, tabulated area. It is a symbol of a community's cultural and social thinking. So, its scope does not include just parks. Plants are the most important environmental variables in the landscape architecture and green space. Given the numerous problems in the field of green space, it seems necessary to provide methods for selecting plants with a systemic and holistic perspective. The genus Allium is one of the largest world florae. This study analyzed the karyotype and chromosome structure in five populations of Allium hirtifolium in different parts of Van, Turkey. Pre-treatment, fixation, hydrolysis and staining were done using root meristem; then microscopic samples were elucidated. The results showed that in all studied cells of each population, the basic chromosome number was 2n=2x=16 and all of them were diploid and X=8. Karyotype analysis of each population. It was also separately conducted and several indices including length of the long arm, length of the short arm, length of satellites, total length of the chromosome, arm ratio and centromere index. The length of chromosomes in all populations was estimated as 12.53 – 18.64 micrometers. Chromosomes 6 and 8 contained a secondary constriction and satellite. Karyotype formula for these populations was seven metacentric one submetacentric. © 2022 Association of Agricultural Technology in Southeast Asia. All rights reserved.
