Abstract | Seeds of ten species with wide distribution and of feed and medicinal value were subjected to salt stress by germinating them on a substrate enriched with NaCl or NaHCO3. Final germination (G(F)) and radicle length were reduced for all species, and mean germination time (MGT) was extended to varying degrees as concentrations of NaCl and NaHCO3 increased. Once stress was withdrawn, seeds of Suaeda rigida, Halocnemum strobilaceum, Halostachys caspica and Salicornia europaea germinated irrespective of whether the source of stress had been NaCl or NaHCO3 whereas those of Suaeda glauca and S. heterophylla were able to germinate when the source of stress had been NaCl. Degree of salt tolerance during germination was evaluated comprehensively through subordinate function analysis, GF, MGT, radicle length and recovery. Overall ranking of species in descending order of tolerance to NaCl was as follows: Halocnemuin strobilaceum, Suaeda rigida, Halostachys caspica, S. arcuata, Halogeton arachnoides, Salicornia eizropaea, Suaeda heterophylla, S. glaeda, Chenopodium aristatum and S. stellatiflora; the ranking for tolerance to NaHCO3 was Halocnemum strobilaceum, Halogeton arachnoides, Halostachys caspica, Suaeda rigida, S. arcuata, Salicornia europaea, Suaeda heterophylla, S. glauca, Chenopodium aristatum and S. stellatiflora. The top four plants can be used for soil improvement or gene mining. |
