Salt tolerance in Suaeda maritima (l.) dum. fine structure and ion concentrations in the apical region of roots
journal contribution
posted on 2023-06-08, 11:33 authored by M A Hajibagheri, A R Yeo, Tim FlowersAnatomy and ion concentrations have been studied in the roots of the halophyte Suaeda maritima (L.)Dum. growing in saline and non-saline conditions. The roots were fine with only three layers of cortical cells. Salinization of the growth medium resulted in cellular vacuolation commencing closer to the apex than in non-salinized plants and led to an increase in root dimensions through increased cell (vacuole) size but not increased cell numbers: the Casparian strip developed much closer to the apex and was twice as long in salt-grown plants. Ion concentrations were determined in sections (1 mm) of root. The apical 1 mm was predominantly non-vacuolate, with a K+ concentration greater than 100 mol m-3 and a Na: K ratio less than 2, even when growing in 340 mol m-3 NaCl. The adaptive value of the anatomical observations are discussed and the ion concentration data assessed in relation to current concepts of the haiophyte cell.
