Water deficiency is the most problem for cultivating of fig (Ficus carica) in Iran. The research has been made in 2008 using “Green”, “Black”, “shah anjir” and “Matthew” local cultivars to study the stoma behavior of leaves in different systems of deficient irrigation in Ferdowsi University of Mashhad. Four level (treatments) of irrigation including supplying enough water for vases (100% field capacity) mild tension (75% field capacity) average capacity(50% field capacity)and severe capacity(25%field capacity) were applied. The results showed that the length, width and size of the stoma, width and size of guard cells decreased in treatments under severe dry stress but among the different types, the“Green” cultivar one had the least length, width and size of stoma and the least width and size of guard cells.
