Title ECO-PHYSIOLOGICAL ANALYSIS OF CHENOPODIACEAE SPECIES IN SALINE SOILS OF THE SOUTHERN URALS
Source Rastitel'nye Resursy
Abstract The Chenopodiaceae species were studied in saline soils of the Southern Urals and the geo-botanical descriptions and eco-physiological analysis were carried out of four dominant Chenopods species (two annuals and two perennials with different type of photosynthesis).: Atriplex tatarica L. (C-4 NAD- ME), Bassia sedoides (Pall.) Aschers. (C-3-C-4 NADP-ME), and A. verrucifera M. Bieb. (C-3), Kochia prostrata (L.) Schrad. (C-4 NADP-ME). The optimal and pessimal habitats were identified for the studied species (by growth characteristics). Two annual species A. tatarica and B. sedoides were characterized by the greatest differences in the accumulation of biomass in favorable and unfavorable habitats (up to 10-fold), that pointed to ruderal strategy of adaptation. For perennial species A. verrucifera and K prostrata similar differences were less pronounced. The obligate halophyte with C-3 type photosynthesis A. verrucifera was the most salt tolerant species. The drought and salt toleration in group of C-4 plants increased gradually from NADP-ME to NAD-ME type.
