Pistachio is one of the most important of horticultural products in Iran. Numerous of diseases are affected to pistachio in the world. Gummosis, verticillium wilt and root-knot nematodes are the most important diseases in the world. Root-knot nematodes, Meloidogyne species, are endoparasitic nematodes that reduced products and cause to structural, physiological and biochemical disorders in plants. Severity of damage is depended on species and intensity population nematode. In this survey, pistachio gardens of Mahvelat region (Razavi Khorasan province – Iran) with two cultivars, Ohadi and Badami, were studied. Meloidogyne javanica was found in the area with high populations. The experiments were setup with 50 replications in 2×5 factorial experiment in an imbalanced Completely Randomized Design. Number of galls and egg mass on the roots were measured. Amount of leaf chlorophyll, leaf surface, leaf necrosis, tree height, east-west spread, north-south spread, growth of annual branch, diameter of annual branch and fruit yield were determined. Results showed that with increasing of gall index/egg mass, growth characteristics of plant were significantly reduced according to Tukey test. There was no difference among the treatments about leaf necrosis and diameter of annual branch. Amount of chlorophyll and fruit yield in Badami cultivar were decreased significantly comparing with Ohadi cultivar.
