Abstract

The effects of seed hardening treatments using different salt solutions on the germination, emergence and seedling vigor in coarse and fine rice were investigated in a laboratory trial. Seeds were hardened both using tap water (referred to as hardening) and with CaCl₂, KNO₃, KCl, NaCl solution (osmohardening) in such way that osmotic potential of all the solutions was - 1.25 MPa. In both coarse and fine rice, osmohardening with CaCl₂ performed the best compared with all other treatments as indicated by lower values of time to start germination, MGT, T₅₀ and MET and higher values of final germination and emergence, speed and energy of germination, root and shoot length and seedling fresh and dry weight. Simple hardening and osmo-hardening with KCl were next best treatments.
