Abstract

In order to study the effect of mycorrhizal fungi on growth and nutrients uptakeof Mexican marigold (Tagetes minuta) under Salinity stress, a pot factorial experiment based on completely randomized design with three replications was performed in the horticulture greenhouse of Agriculture Faculty, Ferdowsi University of Mashhad in 2017. The first factor was mycorrhizal fungi application at three levels (without inoculation, Rhizophagus intradices and Funnetiformis mosseae) and the second factor included four levels of Salinity of irrigation water (0, 40, 80 and 120 mM NaCl). The results showed that all growth characteristics severely decreased because of Salinity stress, and application of mycorrhiza cause to moderate harmful effects of Salinity and plant tolerance to Salinity. The highest node number (12. 89), stem diameter (7. 49 mm), plant height (65. 75 cm) and number of branches (23. 33) were obtained in no Salinity treatment along with R. intradices. With increasing Salinity, the contents of phosphorus, calcium, sodium, chlorine and nitrogen of the leaves increased and in opposite the contents of potassium, manganese, zinc and iron decreased. The highest content of leaf phosphorus (8. 5 mg/g leaf dry weight) was recorded in the highest level of Salinity stress and F. mosseae application. The highest sodium content (12. 33 mg/g leaf dry weight) and leaf chlorine (63. 09 mg/kg dry leaf weight) were observed in Salinity (120 mM) treatment without mycorrhiza application. While, the highest content of leaf potassium (6. 23 mg/g leaf dry weight) was observed in control (no Salinity treatment without application of mycorrhiza fungi), the highest leaf Mn (143. 91 mg/kg dry weight) in 40 mM Salinity treatment and F. mosseae application, and the highest amount of Zn (7. 12 mg/kg dry weight) in the treatment without Salinity and F. mosseae application were observed. The results of this experiment showed that Salinity cause to reduce the growth and in this condition the application of mycorrhiza cause to improve the growth and nutrient uptake. Use of mycorrhiza fungi in particular F. mosseae is recommended as a suitable solution for increasing Salinity resistance in Mexican marigold.
