Types of priming
- Hydro priming (use of water double the volume of seed)
- Halo priming (use of salt solution-NaCl)
- Osmo priming (use of osmotic solution – PEG)
- Sand matric priming – (use of moist sand)
Methodology
For the first three methods soak the seed in the respective solution of definite concentration for needed duration and dry back the seed to original moisture content.
For the fourth method mix the seeds with moist sand of required water holding capacity, place it in perforated plastic covers and keep it deep in the tray filled with moist sand of same water holding capacity.
