عنوان Co-inoculation of mycorrhizal fungi and Streptomyces on morphometric indices of grapevine (Vitis vinifera L.) under salt stress

نویسندگان Arefeh Noori - Rouhollah Karimi

چکیده The use of biofertilizers in agriculture has always been recommended by plant nutrition experts. Considering the role of fungi and bacteria in reducing the effects of environmental stresses, including saline soils, in present study, the effect of the single and combined (co-inoculation) application of Glomus mosseae (Gm) AMF and Streptomyces rimosus (Sr) PGPR on salt tolerance of Sultana grapevine (Vitis vinifera L.) was performed. Based on results, the combined inoculation with Gm AMF and Sr PGPR markedly improved shoot and root morphometric traits compared to those vines inoculated with these symbionts alone or uninoculated vines under saline condition. The highest main root length was related to inoculated vines with Sr PGPR, which was 18.5% higher than uninoculated control plants under saline condition. Under saline condition, co-inoculation with Gm AMF and Sr PGPR decreased leaf necroticindex by 31% compared with control uninoculated plant. Therefore, combined application of Gm AMF and Sr PGPR assisted host plants to uptake higher nutrients during salt stress; confer salt tolerance to vines by increase in morphometric traits.
