MEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
متن کاملRemote sensing estimates of glacier mass balances in the Himachal Pradesh (Western Himalaya, India)
Although they correspond to an important fraction of the total area of mountain glaciers (33000 km out of 546000 km), Himalayan glaciers and their mass balance are poorly sampled. For example, between 1977 and 1999, the average area surveyed each year on the field was 6.8 km only. No direct mass balance measurement is available after 1999.
