tailieunhanh - Effect of arbuscular mycorrhizal fungi on growth parameters of sweet corn under NaCl salinity

During last few decades the mechanism of salinity tolerance in plants, from the whole plant level to cellular and gene level, has been the subject of numerous studies. However parts of the mechanism of plant salt tolerance are still mysterious. Among one third of the irrigated land is suffering from secondary salinization an alarming situation that is referred to as the “quiet crisis”. We hypothesize that arbuscular mycorrhiza (AM) fungi is one of the possible Bio-ameliorator for salinity stress and play a significant role in alleviation of salt stress to greater extent. To prove our hypothesis and to investigate the effect of salt stress levels (50, 75, 100 mM NaCl) on growth performance of sweet corn considered as a salt sensitive and susceptible species. An experiment was carried out to determine the role of AM fungi by comparing mycorrhizal fungi inoculated sweet corn plant that are experimental to non- inoculated sweet corn plants that are control with respect to salt stress. There was a great difference in responses of sweet corn cultivars to salt stress. Plants inoculated with AM fungi shows better growth performance, higher biomass and yield as compared to non- inoculated plants. | Effect of arbuscular mycorrhizal fungi on growth parameters of sweet corn under NaCl salinity
