The Role of Arbuscular Mycorrhizal Fungi and Salicylic Acid in Success of Culturing Ocimum Basilicum L. in Aluminum – Contaminated Lands

Abstract

Aluminum stress is considered as limiting factor of plant performance. Many studies showed that inoculating plants by mycorrhizal fungi and using salicylic acid increased the resistance of many plants against heavy metals toxicity. The purpose of this study was to consider the role of Glomus mosseae and Glomus intraradices fungi and of salicylic acid in increasing resistance of green basil against aluminum toxicity. This experiment was performed in factorial plan based on random blocks in greenhouse conditions. The results of this study showed that aluminum caused increase in reduced sugar in shoot and root and increase in proline in shoot, while destructive effects of aluminum chloride were adjusted in pretreated – salicylic acid or inoculated – mycorrhizal fungi plants.
