Mycorrhizal impact on Ocimum basilicum grown under drought stress

Abstract

Abstract Background Ocimum basilicum was grown under three levels of drought stress (100% Field capacity, 70% Field capacity, and 40% Field capacity). Half of the plants were inoculated with Arbuscular mycorrhiza and the other half was not inoculated. Arbuscular mycorrhizal fungi (AMF) were applied to improve plant growth and to alleviate drought stress on sweet basil. Results Drought Couse inhibition in the colonization of Arbuscular mycorrhiza, reduction in plant growth, decrease stomatal size increase stomatal density, a decline in soluble carbohydrates, accumulation of amino acids, proline, and glycine betaine, and reduction in some minerals such as P, K, and Na. Conclusions The effect of drought was alleviated by the application of inoculation with Arbuscular mycorrhiza.
