Accumulation Na +, Ca2+, Mg2+ & Cl- ions in pollen and flowers under saline conditions and their effects on pollen viability


, : Accumulation Na +, Ca2+, Mg2+ & Cl- ions in pollen and flowers under saline conditions and their effects on pollen viability. Indian Journal of Experimental Biology 11(5): 465-466

Flowers, pistils and anthers from Petunia hybrida grown in saline culture (NaCl, CaCl2 or MgCl2) singly or in various combinations at 0, 1, 2 or 3 bars osmotic pressure, were anlysed for Na+, Ca2+ and Mg2+ contents. With increased osmotic pressure concentrations of all the cations increased in the flowers, Na+ and Ca2+ increasing in pistils and anthers but Mg2+ decreasing indicating differential selectivity of floral parts for the accumulation of ions.
