REPRODUCTIVE-BIOLOGY OF 2 ARCTIC SPECIES OF MEADOW GRASS

The biology of the reproduction of two arctic species of meadow grass, Paa alpigena (Blytt) Lindm. and P. sublanata Reverd., and their intra specific pseudo-viviparous taxa was studied during: 1993-1994 on the c oasts of the southern parts of the Gulf of Ob and Taz Bay. It was show n that pseudo-viviparous taxa were able to regularly form viable seeds . The total production of ripe diaspores of pseudo-viviparous taxa per unit area exceeded the amount of seeds produced by seed plants of the same species.
