ADDITION TO CHARACTERS OF ENDEMIC AUBRIETA CANESCENS SUBSP CANESCENS BORNM. (BRASSICACEAE) FROM TURKEY

Abstract

Investigation on the taxonomical, morphological, anatomical, karyological and ecological characteristics of the endemic Aubrieta canescens ssp. canescens Bornm. growing in Turkey was carried out. Data were obtained at the flowering and fruiting times of populations. The sampling was made from various locations in each year from 2012 to 2014. In morphological studies, description of the endemic taxon stated in the Flora of Turkey revised in the light of detailed evaluations of many specimens, and features exclusive to the taxon. Additionally, images were taken about the seed's surface of different taxa by using Scanning Electron Microscope micromorphologically. Structures of the stem, root and leaf cross-sections were examined in anatomical studies. In karyological studies, the chromosome number of the taxon was found as 2n = 16 (x = 8) and consisted karyotype formula of taxon as five median, two submedian, one subtelocentric and one telocentric chromosome pairs. In general, the physical features of the soil and live together taxa of the examined taxon were investigated ecologically. This study is the first one where morphological (macro and micro), anatomical, karyological and ecological features of endemic Aubrieta canescens subsp. canescens was carried out. According to IUCN criteria, risk category of the taxon was also identified.
