Salinity-induced changes in the morphology and major mineral nutrient composition of purslane (Portulaca oleracea L.) accessions

This study was undertaken to determine the effects of varied salinity regimes on the morphological traits (plant height, number of leaves, number of flowers, fresh and dry weight) and major mineral composition of 13 selected purslane accessions. Most of the morphological traits measured were reduced...

Most of the morphological traits measured were reduced at varied salinity levels (0.0, 8, 16, 24 and 32 dS m⁻¹), but plant height was found to increase in Ac1 at 16 dS m⁻¹ salinity, and Ac13 was the most affected accession.
