There are around 100 species in the Suaeda genus; 27 of them are common in the CIS. Most species grow under the drought
condiƟons typically in semi-deserts and deserts. One of the promising species for in vitro culƟvaƟon is Suaeda heterophyl-
la (Kar. et Kir.) Bunge. It is the annual haloxeromesophilic plant, growing on the salt-flats in Central Asia, the Russian South-
East, the Caucasus, Iran and Afghanistan. As arid soils oŌen accumulate different ions responsible for salinaƟon the aim of
the research was to test seed germinaƟve ability of dimorphic fruits of Suaeda heterophylla influenced by chlorides, sul-
phates and their combinaƟon. Both fruit types were treated with the following salt concentraƟons: NaCl and Na2SO4 — 0.5,
1.0 and 3.0 %, combinaƟon of NaCl and Na2 SO4 (1:1) — from 1.0 to 6.0 %. For the first fruit type opƟmal concentraƟons of
NaCl and Na2SO4 made up 3 and 4-5 % being 1 and up to 3 % respecƟvely for the second one. S. heterophylla showed the
low adaptability (1 %) to the mixture of NaCl and Na2SO4 (1:1). Different responses of polymorphic seeds to salinity favour
seed bank conservaƟon having a tremendous importance for species’ survival for a long period under extreme condiƟons.
Keywords: Suaeda heterophylla, annual halophyte, seed, germinaƟve ability, chloride, sulfate salinity.
