Abstract
Two field experiments were conduct during summer season of 2006 and 2007 at Tag El-Ezz Research Station, Dakahlia Governorate, Egypt; to study the effects of gibberellins, cytokinins and urea to increase tolerance of rice plants for high levels of salts. In addition, the best treatment through the interaction between them, as well as the salt level that gives the best productivity of rice yield.
High salinity levels led to decreased total chlorophyll, ascorbic acid and soluble sugars content in rice plant especially in the sensitive rice cultivar, on reverse of proline content. Using growth substances, urea, and their combinations increased total chlorophyll, ascorbic acid and soluble sugars content in rice plant especially in the sensitive rice cultivar, but on reversal that proline content.
