EFFECT OF SALTS ON SEED GERMINATION AND SEEDLING GROWTH OF PENTATROPIS NIVALIS (J.F.GMEL.) D.V. FIELD & J.R.I. WOODA.V. Shevate and B.S. MaliAbstract Effect of various concentration of (0.5, 1, 1.5, 2%) Nacl, Cacl2, MgSO4 and K2SO4 on seed germination of Pentatropis nivalis showed variation 90 to 99% seed germination in distilled water (Control) but germination was observed in 0.5 to 2 percent chloride and sulphur salts which range from 5 to 85 percent. The decreased germination occurs due to low osmotic or toxic effects of ions. The higher germination percent in two form of various concentration of chloride and sulphur indicate the salinity tolerate capacity at germination level. Thus it is clear that the seed here less sensitive to Nacl, Cacl2, MgSO4 and K2SO4. |
