A study of different irrigation treatments with moderate saline ground water for two-year-old seedlings of Cupressus sempervirens L. (cypress) and Pinus brutia Tenore (calabrian pine) was applied within two successive seasons of 2005 and 2006 to examine the root growth and some chemical compositions. Irrigation treatments were applied as: tap water (control), twice saline water followed by one time tap water (2i1 cycle), four times saline water followed by one time tap water (4/1 cycle) and totally saline water (Stressed). At the end of second season, the results indicated that the totals of length, perimeter, surface area, specific length of fibrous roots (SRL) and specific area of fibrous roots (SRA) of both cypress and calabrian pine seedling roots decreased significantly when irrigated by different cycle treatments of saline ground water except SRL of cypress roots that showed no statistical differences.
