Bacillus subtilis QM3 is a strain of antagonistic strains which have biological control
function. Salinity is the most important
limiting plant factor for agriculture development and growth changes in wheat. The present study was carried out to test tolerance involved in salt stress
alleviation in wheat (Triticum aestivum L.) through the root application
of B. subtilis QM3. Experiment was performed
after germinating for two days. Wheat root was first grown under B. subtilis QM3
with four levels (108 CFU/ml B. sutilis QM3 (M1), 107 CFU/ml B. subtilis QM3
(M2), 106 CFU/ml B. subtilis QM3 (M3) and 105 CFU/ml B. subtilis QM3 (M4)), then poured with saline regime of NaCl of six concentrations (50, 100, 150, 200, 250,
300 mmol/L) compared along with control. The results of present study showed that B. subtilis QM3
clearly promoted the growth of the root morphology and the content of
osmoregulation substance (p <
0.05), and 106 CFU/ml B. subtilis QM3 (M3) was found
to be very effective in mitigation of NaCl stress by promoting the growth
of the wheat root and adjusting the content of osmoregulation
substance in wheat root.
