A significant possibility to agricultural productiveness all over the world is certainly as a result of environments with annoying components together with drought, salinity, waterlogging, severe temperatures, non-optimal degrees of mineral meals and so forth. according to contributions provided on the foreign convention on Biosaline Agriculture and excessive Salinity Tolerance in November 2006 in Gammarth, Tunisia, this e-book reports the present kingdom of information in biosaline agriculture and excessive salinity tolerance in crops. It generally specializes in the biotic method of economically make the most of the stress-prone parts by means of starting to be resistant plants.
This quantity contains 3 sections: physiology and biochemistry, ecology, and molecular biology. hence, a scientific process has been followed to discover plant responses to numerous ecological elements at physiological and molecular levels.
It is of curiosity to scholars, researchers and execs in plant body structure, molecular biology, biotechnology, agriculture, soil technological know-how, and environmental biology.

However, in the present study, only chlorophyll ‘b’ content Growth enhancement in maize and wheat under salt stress 25 Figure 2. Leaf GB, proline, chlorophyll ‘a’ and ‘b’ of wheat when different amounts of GB were exogenously applied to salt-stressed or non-stressed plants (0, no spray; 50, 50 mM GB; and 100, 100 mM GB foliar spray). was improved under saline conditions as a result of GB application (Fig. 2c, d). As chlorophyll ‘b’ is mainly associated with PS-II antenna, GB-induced improvement in Chl ‘b’ concentration might have been due to structural/conformational changes in the PS-II antennae, as suggested by Kocheva et al.
The progressive accumulation of these ions in plant tissues leads to well-documented injurious effects . A general effect induced by high salinity in leaf cells is the accumulation of activated oxygen species leading to lipid radical formation and, subsequently, cell membrane breakdown and other severe damage . To prevent this oxidative 38 Rosa M. Pérez-Clemente et al. stress, citrus plants have developed a defense system including detoxification enzymes and antioxidant molecules . Physiological basis of citrus tolerance to salinity It is generally accepted that the capability of citrus plants to tolerate high salinity is particularly dependent upon the rootstock , and, so far, the differences found among citrus rootstocks regarding salt tolerance have been related to their ability to exclude chloride .
