Citrus yield and growth are deeply affected by salinity. In the present work we have studied the effectiveness of different plant growth regulators such as abscisic acid, jasmonic acid and 8´-methylene methyl abscissate in protecting citrus 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 photosynthetic rate were measured. Non-treated plants showed a dramatic drop in photosynthetic activity in response to salinity, 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 change in 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 response to salinity and could be helpful in their acclimation to saline conditions. |
