Abstract :Arbuscular Mycorrhiza insert ignore into journalissuearticles values(AM); is a symbiotic association between plant roots and certain soil fungi. Mycorrhiza establishment is known to modify several aspects of plant physiology such as mineral nutrient composition, hormonal balance, and C allocation patterns. In this study, the effect of the Arbuscular Mycorrhizal fungus Glomus intraradices Schenck & Smith on the physiological growth parameters of pepper insert ignore into journalissuearticles values(Capsicum annuum L. cv Cetinel-150); plants was investigated. To explain the physiological growth of these plants, some physiological growth parameters were determined in the shoots and leaves of mycorrhizal insert ignore into journalissuearticles values(M); and nonmycorrhizal insert ignore into journalissuearticles values(NM); plants such as the P and dry matter insert ignore into journalissuearticles values(d.m.); contents, chlorophyll insert ignore into journalissuearticles values(chl); concentrations insert ignore into journalissuearticles values(chl a, chl b and chl a + b);, and amounts of some reducing sugars insert ignore into journalissuearticles values(fructose, a glucose, b glucose);, sucrose and total sugar. All parameters increased in M pepper plants by 12%-47% compared with those of the NM plants insert ignore into journalissuearticles values(P £ 0.01);. Furthermore, it was determined that P concentration was positively correlated with all chlorophyll and sugar contents. It is concluded that increased P concentration, because of the mycorrhizal symbioses, positively affects the physiological performance of pepper plants.
