Many studies have reported that salinity has a negative impact on mycorrhiza but mycorrhizae can increase plant growth under salinity stress. This study was conducted to determine the growth and level of dependence of Dalbergia latifolia on mycorrhiza under saline conditions. Dalbergia latifolia is inoculated with Glomus etunicatum and grown on media that has been given a different concentration of sodium chloride solution. The results showed that an increase in salinity led to reduced root colonization of G. etunicatum in D. latifolia but on the other hand, the presence of G. etunicatum increased the growth and biomass of D. latifolia in all salinity levels. Phosphorus uptake of plants colonized by G. etunicatum also increased. This result confirms the degree of dependence of D. latifolia on G. etunicatum under salinity stress. Improved growth of D. latifolia in saline soils reflects the importance of G. etunicatum which can be used to improve the productivity of saline soils.
