They apply very coarse and very fine scaling, respectively, but coherence is lost when the various intermediate levels of different scales are neglected. Regarding SALINITY we are clearly dealing with a global problem, which due t

Ultrastructural Effects of Salinity in Higher Plantses, such as the build up of transfer cells and many small vesicles, may be a sign of extensive exchange of substances across membranes. Several examples of structural adjustment of halophytic and glycophytic plant species will be presented in this chapter.

Pressure Probe Measurements of the Driving Forces for Water Transport in Intact Higher Plants: Effecure responses to salinity clearly depends on the transpirational status of the plant, at least for various grass species. Interestingly, application of HgCl. to the root amplifies the effects of salt stress, suggesting that water and solute flows into and out of the root are disturbed by this treatment.

Salinity, Osmolytes and Compatible Solutesal medium and vacuole. Such solutes should be osmolytes that are non-toxic and “compatible” with cytoplasmic enzymes over wide concentration ranges. A number of such solutes have been identified, their pathways of synthesis elucidated, and progress has been in isolating genes encoding key enzymes of their biosynthetic pathways.

Global Impact of Salinity and Agricultural Ecosystemsion of agricultural lands is particularly widespread in arid and semiarid environments where crop production requires irrigation chemes. At least 20% of all irrigated lands are salt-affected, with some estimates being as high as 50%. Whereas the world’s population continues to rise, the total land a

Salinity in the Soil Environmentriculture. Since the chemistry of soil solutions plays a major role in soil salinity, considerable details on this topic are offered. Chemical speciation in the soil solution should be of importance to plant scientists. The dynamic nature of soil salinity in the rootzone affects performance of plant
