The accumulation of fatty acids in different organs of purslane under salt stress

Purslane (Portulaca oleracea) is an important salt-tolerance plant in the world. Salt stress influenced fatty acid contents and composition. In this study, two purslane genotypes, one cultivated variety (Pakistan Local, ‘PL’) and another wild variety (Liaoning China local ‘LCL’) were chosen. The eff...
