Physiological and biochemical characteristics of Sorghum bicolor and Sorghum sudanense subjected to salt stress in two stages of development

  This study compared the salt tolerance of Sorghum bicolor and Sorghum sudanense plants subjected to salt stress in two distinct phases of development. We analyzed the growth, gas exchange, the relative chlorophyll content (SPAD index) and the accumulation of organic and inorganic solutes. The experimental design was a randomized 2 × 3 × 2 factorial that included two species (S....

Germination strategies of Suaeda species for saline-alkaline environments

  The Songnen Plain in northeastern China has been experiencing severe problems with both salinity and alkalinity. Investigation on seed germination and seedling growth of typical halophytes in Songnen Plain under different saline-alkaline stresses is critical for evaluating the potential of a halophyte for restoration. The interactive effects of salt (NaCl and Na2SO4) and alkali (NaHCO3 and Na2CO3)...
