Salt tolerance & protoplasmic salt hardiness of various woody & herbaceous ornamental plants

Salt tolerance & protoplasmic salt hardiness of various woody & herbaceous ornamental plants.

The interest in salt tolerance of plants, especially those of economic importance, is increasing as more saline lands are brought under cultivation, and as saline irrigation waters add to the salinity of cultivated soils. Research relating to the survival and growth of plants growing on soils containing excessive soluble salts has left many problems unsolved. The task of obtaining and selecting...

Cold Hardiness of Woody Plants

stresses caused by their freezing and thawing. A key difference between a hardy plant and a non-hardy plant is believed to be where the ice forms in freezing: inside the living cells or outside of them. If ice forms inside of cells, it is almost always fatal to them, and this is probably the principal cause of frost kill in non-hardy plants. Normally hardy tissue may be killed by moderate tempe...

Mechanisms of salt tolerance in plants

The increasing prevalence of soil salinity is one of the most significant obstacles to improving crop productivity. Recent advances in genetic and molecular analysis of Arabidopsis thaliana mutants, ion transporters and stress signaling proteins have improved our understanding of the mechanisms of cellular ion homeostasis and its regulation in plants. Since Na toxicity is the principal stress c...

Understanding and Improving Salt Tolerance in Plants

even when ECe is 3.0 dS m 1 (Table 1), which in terms of osmotic potential is less than –0.117 MPa (osmotic One-fifth of irrigated agriculture is adversely affected by soil salinpotential 0.39 ECe). At these salinity levels, the ity. Hence, developing salt-tolerant crops is essential for sustaining predominant cause of crop susceptibility appears to be food production. Progress in breeding for ...
