Male meiosis in reed grass Calamagrostis emodensis Griseb. from cold desert region of Western Himalayas

Abstract

The present investigation involves the meiotic studies on two populations of Calamagrostis emodensis Griseb. (Family: Poaceae) from District Kinnaur, Himachal Pradesh, India in the Western Himalayas. Both the populations reveals tetraploid chromosome count of 2n=28 which is the first ever report for the species. The objective of the present research were to study the detailed meiotic course, microsporogenesis, and the effect of meiotic abnormalities encountered during different stages of meiosis I and II on pollen grain size and pollen fertility.
