Abstract

The present study was undertaken to investigate the osmotic and toxic effect of 0 to 2.5 percent chloride (NaCl, KCl and CaCl2) and sulphate salt (Na2SO4CaSO4 and MgSO4) on seed germination of Trianthema portulacastrum L. at room temperature. Maximum germination (99 percent) was recorded in controlled condition (distilled water). However, germination was adversely affected in various sulphate and chloride salt concentrations. Furthermore, it was observed that the seeds were more sensitive to chloride salts than sulphate salts. However, maximum seed recovery in chloride salts (2 to 45 percent) as compared to seeds germinated in sulphate (0 to 8 percent)was recorded except in Na2SO4. Such observation indicates maximum osmotic or toxic effect in chloride salt treated seeds than sulphate salts treated seeds.
