CYTOMORPHOLOGY OF SOME GRASSES (POACEAE) FROM LAHAUL-SPITI (HIMACHAL PRADESH), INDIA

ABSTRACT

Meiotic study and pollen fertility was investigated in thirty five grass species belonging to twenty three genera from different localities of Lahaul-Spiti. This is the first cytological study in the grasses from this alpine Himalayas. Bromus gracillimus (n=7) and Melica persica (n=10), are cytologically worked out for the first time from world, whereas Calamogrostis pseudophragmites (n=7), Helictotrichon pretense (n=7), Poa lahulensis (n=14), Stipa jacquemontii (n=21, 22), S. koelzii (n=11), S. splendens (n=22), Paspalum distichum (n=28) and P. longifolium (n=30) show the varied chromosome reports at the world level.

Key Words: Cytomorphology, Grasses (Poaceae), Lahaul-Spiti, meiosis.
