Abstracts |
This research was designed to evaluate the effect of mycorrhiza-like endophyte (Sebacina vermifera) on growth, yield and nutrition of rice (Oryza sativa L.) under salt stress. The experimental design was a completely randomized design in factorial with five replicates. Treatments included four solutions of NaCl with different salinity (non-saline (control), 3, 6 and 9 dS/m2) and fungi symbiosis (without fungi inoculation (-MLF) and with fungi inoculation (+MLF)). Results showed that panicle number, grain number, panicle weight and grain yield, which showed significant difference among treatments, were promoted by involving MLF. However, MLF colonization did not significantly change grain number, 1000 grain weight and harvest index of rice plants. Tolerance index (Ti) of rice plants markedly decreased with an increase of salt stress; however, application of MLF caused a significant increase in Ti under slightly to moderate salinity levels. MLF inoculation promoted P, N and Zn uptake under slightly and moderate salinity (S1 and S2) as well as control plants. Microscopic inspection of roots inoculated with S. vermifera detected heavy colonization and abundant production of chlamydospores in root cells. Generally, the results of this experiment indicated a positive and ameliorate effect of MLF fungi on rice performance under salinity stress. |
