New chromosome counts for Nepeta Lamiaceae from flora of Iran

Abstract

Nepeta species L. are annual and perennial plants of Lamiaceae which is a significant plant due to it's medicinal charecteristics. In this study the seeds of eight populations belonging to four species namely, N. eremophila, N. saccharata, N. Bornmulleri, N. mahanensis were collected for the chromosome count survey. The terminal meristem of root and squash technique was used for karyological studies. The results revealed eqaul choromosome number; 2n=2x=18 for the species studied. Therefore the basic choromosome number in all investigated species was x=9

Keywords
