Halotolerant bacteria mitigate the effects of salinity stress on soybean growth by regulating secondary metabolites and molecular responses

Table 1 Growth promoting effect of Isolate ALT29 and ALT43 in soybean under various NaCl stress. The values with ± show standard deviation (SD) are means of three technical replicates. Value in columns followed by different letters are significantly different as evaluated by DMRT analysis
