Chromosome numbers in six species of Scrophularia L. from cold desert regions of Lahaul-Spiti, H. P., India

Chromosome Number and Secondary Chromosomal Associations in Wild Populations of Geranium pratense L. from the Cold Deserts of Lahaul Spiti (India)1

In this work we studied the meiotic chromosome number and details of secondary chromosomal associations recorded for the first time in Geranium pratense L. from the alpine environments in the cold deserts of Lahaul Spiti (India). All the presently studied individuals of the species existed at 4x level (x = 14). The present chromosome count of n = 28 in the species adds a new cytotype to the alr...

Chromosome Numbers and Karyotypes of Four Species Rubus L. from North of Iran

Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...

Chromosome Numbers for Some Erodium L'Hér (Geraniaceae) Species of Iran

Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...

Elevation Change Rates of Glaciers in the Lahaul-Spiti (Western Himalaya, India) during 2000-2012 and 2012-2013

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
