Caryological and physiological characteristics of rare species Potentilla porphyrantha Juz. (Rosaceae) in Armenia

Abstract

Caryological and physiological features of rare species Potentilla porphyrantha Juz. were investigated. It was shown that this species is diploid with 2n = 14 (x = 7). Physiological investigation included study of water regime, intensity of transpiration and photosynthesis. It was shown, that this species growing in-situ conditions on Amulsar Mountain (2900 m a.s.l.) now is very good adapted to ex-situ conditions in the Sevan botanical garden (1900 m a.s.l.). It grows very well, bloom and produce viable seeds, and in the future could be reintroduced into nature.
