in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

The role of zinc (Zn) in enhancing defense capacity of several plants against salinity has been demonstrated but there is limited information on the impact of Zn nutrition on alleviating salinity-induced oxidative damage in olive. One-year-old seedlings of two varieties of olive (Olea europaea L. cvs. Frontoio and Conservolea) supplied with three Zn levels (0, 1 and 5 mM in the form of ZnSO4.7H...

abstract verticillium wilt of olive caused by verticillium dahliae is one of the main constraints to olive production in golestan province. in this research, two defoliating and two non-defoliating isolates of the fungus were inoculated in 16-18 months-old olive seedlings. the seedlings consisted of concervolia, cronaiki, kalamon, zard-roghani, bladi, mission, manzanilla and sevillana. the seed...

verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzanilla, were transplanted to different sets of pots each pot containing 2000g of sterilized sandy loam soil. the experiment was conducted in a completely randomized design of 32 treatments, each in five replications. treatments were comprised of: control, mere nematode, mere fungus, and fungus+nematode. pots were inocul...

We investigated the role of terpenoid aldehydes in the resistance of cotton (Gossypium hirsutum) to the root-knot nematode (Meloidogyne incognita). Three-day-old, root-knot-resistant ('Auburn 623') and -susceptible ('Deltapine 16') seedlings were inoculated with M. incognita. Comparable portions of inoculated and noninoculated roots were harvested 2, 4, 7, and 10 days later. Terpenoid aldehydes...
