“…It has long been recognized as a hormone which is upregulated due to soil water deficit around the root. Salinity stress causes osmotic stress and water deficit, increasing the production of ABA in shoots and roots (He and Cramer 1996;Popova et al 1995). The safflower cultivars respond differently toward salinity stress by increasing Ca 2+ and Cl − to a lesser extent while Na + in their shoots and roots by decreasing the fresh/dry weight ratio (Gadallah 1996).…”

“…With stressed plants, ABA application reduced the toxicity of salt treatment, improved K + uptake under salinity, effectively increased K + / Na + ratio, helped the plants to avoid Na + toxicity, and sometimes enhanced growth. The association between the internal mineral element concentrations was largely affected by ABA The accumulation of ABA can mitigate the inhibitory effect of salinity on photosynthesis, growth, and translocation of assimilates (Jaschke et al 1997;Popova et al 1995). The positive relationship between ABA accumulation and salinity tolerance has been at least partially attributed to the accumulation of K + , Ca…”

Safflower is one of the oldest cultivated crops, usually grown at a small scale. Safflower is grown for flowers used for coloring, flavoring foods, dyes, medicinal properties, and livestock feed. Safflower is underutilized but gaining attention due to oil yield potential and the ability to grow under high temperatures, drought, and salinity. Salinity and drought have negative effects by disrupting the ionic and osmotic equilibrium of the plant cells. The stress signal is perceived by membranes then transduced in the cell to switch on the stress responsive genes. This review discusses on stress tolerance mechanisms in safflower. Strategies are proposed for enhancing drought and salt resistance in safflower.

“…Its powerful functions in salt stress reflected its involvement in photosynthesis and growth, osmotic tolerance, ion homeostasis and in the antioxidant defense responses discussed earlier. Two decades ago, Popova et al (1995) has proposed that the inhibitory effect of salt stress on growth and photosynthesis can be alleviated by ABA. Moreover, ABA participates in regulating stress-related-gene expression.…”

The increasing seriousness of salinization aggravates the food, population and environmental issues. Ameliorating the salt-resistance of plants especially the crops is the most effective measure to solve the worldwide problem. The salinity can cause damage to plants mainly from two aspects: hyperosmotic and hyperionic stresses leading to the restrain of growth and photosynthesis. To the adverse effects, the plants derive corresponding strategies including: ion regulation and compartmentalization, biosynthesis of compatible solutes, induction of antioxidant enzymes and plant hormones. With the development of molecular biology, our understanding of the molecular and physiology knowledge is becoming clearness. The complex signal transduction underlying the salt resistance is being illuminated brighter and clearer. The SOS pathway is the central of the cell signaling in salt stress. The accumulation of the compatible solutes and the activation of the antioxidant system are the effective measures for plants to enhance the salt resistance. How to make full use of our understanding to improve the output of crops is a huge challenge for us, yet the application of the genetic engineering makes this possible. In this review, we will discuss the influence of the salt stress and the response of the plants in detail expecting to provide a particular account for the plant resistance in molecular, physiological and transgenic fields.

“…5). On the other hand, treatment with ABA modifies the behaviour of CO 2 assimilation in saline conditions and appears to protect the photosynthetic machinery, as described in other species exposed to conditions of water deficit or high salt concentrations (Popova et al, 1995;Rajasekaran and Blake, 1999).…”

“…Pre-treatments with ABA effectively increased salt tolerance in crops such as tobacco and barley and forest species such as Pinus banksiana Lamb. (Larosa et al, 1987;Popova et al, 1995;Rajasekaran and Blake, 1999). In spite of this beneficial effect, ABA could have a limited effect since it could form conjugates and/or be degraded rapidly (Cutler and Krochko, 1999).…”

Citrus yield and growth are deeply affected by salinity. In the present work we have studied the effectiveness of differentplant growth regulators such as abscisic acid, jasmonic acid and 8-methylene methyl abscissate in protectingcitrus from salt-induced damage. Plants of Salustiana cultivar grafted onto Carrizo citrange were used for this purpose.Plants were watered with 100 mM NaCl and leaf abscission, ethylene production, chloride accumulation and net photosyntheticrate were measured. Non-treated plants showed a dramatic drop in photosynthetic activity in response tosalinity, an increase in leaf ethylene production and a high abscission rate as a result of a massive leaf chloride accumulation.Plants treated with jasmonic acid or 8-methylene methyl abscisate did not show any physiological changein response to salt stress. However, plants treated with abscisic acid showed a high reduction in the parameters considered.These results suggest that abscisic acid plays a role in modifying citrus physiological behaviour in responseto salinity and could be helpful in their acclimation to saline conditions
