Abstract
Glomalin is a glycoprotein produced by arbuscular mycorrhizal (AM) fungi, and is a major component of soil organic matter, which plays an important role in soil aggregation and carbon sequestration. Glomalin is produced only by the AM fungi. On the other hand, stressful environments such as salinity can affect the AM fungi .The purpose of this study was to investigate the effect of NaCl salinity on glomalin production by Glomerales in symbiosis with corn plant. A factorial experiment was conducted in completely-randomized design (CRD) with four replications in a greenhouse. Factors were NaCl salinity with three levels (S0: 1.34, S1:4 and S2: 8 dS/m) and mycorrhizal fungi with four levels (non mycorrhizal, Glomus versiforme, G. intraradices, G. etunicatum). The results showed that the interaction of salinity and mycorrhizal fungi on plant dry weight, leaf proline, root colonization percentage, EEG and TG was significant at p
