Abstract:
The present study was undertaken to assess the efficacy of biopriming of tomato seeds with different dilutions of Bacillus paralicheniformis suspension viz., 1:1 dilution suspension, 1:2 dilution suspension and 1:3 dilution suspension against salinity stress conditions. The assessments were made on various seed quality parameters such as speed of germination, germination per cent, length of root and shoot, dry matter production and vigour index. The results of this study revealed that the biopriming with undiluted bacterial suspension showed improvement in seedling performance when compared to control, hydropriming and other dilution suspensions of Bacillus paralicheniformis. Also, the increase in salinity stress decreased the physiological performance of tomato seeds. Hence, if tomato crop is to be raised in salinity stress conditions, seed biopriming with Bacillus paralicheniformis can be adopted to overcome the stress and to produce normal healthy seedlings.
