Abstract:

Study was conducted to determine the effect of seed bio-priming on germination and vigour of rice under salinity stress condition. Seeds of rice var. PMK (R) 4 were primed with water, liquid formulation of azospirillum, phosphobacteria, silicate soluble bacteria and their combinations at 20% concentration for 18 h. at 250C and evaluated under salt stress conditions created by 0.25, 0.50, 0.75 and 1.0% NaCl solutions for its germination, vigour index, seedling length, dry matter production, total phenol, chlorophyll and malondialdehyde content were studied. The untreated dry seeds served as control. Results revealed that seeds bio-primed with combinations of azospirillum + phosphobacteria @ 20% solution for 18 h performed better in germination and vigour and also maximum phenol content and lower MDA content at 8dSm-1 NaCl concentration. The next best bio-inoculant was 20% of azospirillum alone. Hence, suggested azospirillum + phosphobacteria @ 20% solution as a best seed enhancement technique for improving seed germination of rice under salinity stress condition.
