ABSTRACT

Seventeen cultivars of annual flower plants from the collection of Tyumen State University were studied from the point of view of resistance to salinization. The cultivars belong to five species: California poppy (Eschscholzia californica Cham. family Papaveraceae), common flax (Linum usitatissimum L., family Linaceae), and three species from family Asteraceae: Tagetes erect (Tagetes erecta L.), small flowering tagetes (Tagetes patula L.), Chinese Callisaurus (Callistephus chinensis (L.) Nees.). These species are used in the floral compositions in Tyumen and other settlements of Tyumen region. The study was performed in controlled laboratory condition on the provocative background by using NaCl solution in three concentrations: 0.15, 1.05, and 1.95%. Cultivars differed considerably according to their reaction to salinization stress, that is, according to germination capacity in vitro and main characters of germs (length and biomass). The cultivars were separated into three groups relative to chloride salinization and according to the complex of characters considered as indicators: into cultivars with high, medium and low resistance.
