PERNUS, Mayté  and  SANCHEZ, J. A. Salinity in Cuba and pre-germination hydration-dehydration treatments of seeds. Pastos y Forrajes [online]. 2015, vol.38, n.4, pp.379-392. ISSN 0864-0394.

Soil salinity is one of the main abiotic factors which affect the establishment and productivity of plants, effect that is increased at global scale. An easily implemented ecotechnology which has proven to be efficient to improve the germination, growth and productivity of cultivated and wild plants, in different stress scenarios (e.g. hydric, heat, acid and salinity), is the hydration-dehydration (HD) treatment of the seeds. This review reports about the salinity status of Cuban soils, the main effects of salinity on plants and the different technologies that exist for the management of saline soils. The positive effects of the HD treatments on the performance of plants under salinity conditions are discussed, as well as theoretical and practical aspects related to the application of these physiological procedures to facilitate their introduction in agroforestry and silvopastoral practices.

Keywords : stress; soil management.
