Sustainability | Free Full-Text | Effects of Sodium Chloride and Sodium Sulfate on Haloxylon ammodendron Seed Germination


Haloxylon ammodendron is a perennial xerophyte that may survive in extraordinarily harsh desert situations of Central Asia. This examine evaluated the impact of salinity, and their capability to get better on seed germination of H. ammodendron, which have been collected at three completely different desert areas, Bakanas takyr plain (H1), Gurbantüngüt Desert (H2), and Gobi Desert (H3), respectively. Seeds have been handled with completely different concentrations of NaCl and Na2SO4 (0.00 (management), 0.05, 0.10, 0.20, 0.40, 0.60, 0.80, 1.00, 1.20, and 1.40 mol/L) to detemine the germination and get better capability to salt stress. The outcomes of the examine have been that H. ammodendron have been extra immune to Na2SO4 than to NaCl. Concerning inhibition of seed germination H. ammodendron was within the following order: H3 > H2 > H1. Based mostly on the tolerance and restoration, seeds will be demonstrated as follows: NaCl: H3 > H1 > H2; Na2SO4: H1 = H2 = H3. Non-germinated seeds in all salt remedies with low osmotic potential confirmed excessive restoration when transferred to distilled water, indicating that these remedies weren’t too poisonous to have an effect on seed viability. These outcomes recommend that H. ammodendron can stand up to excessive ranges of salinity at three desert environments. Thus, H. ammodendron may very well be used to reconstruct vegetation and sustanbility improvement within the desert areas with excessive salinity.
