This study take celery (Apium graveolens L.) and lettuce (Lactuca dolichophylla Kitam.) that are vulnerable to contamination by soil Cd and Pb as the object. Two pot experiments were conducted to investigate the variations, transfer potential, and stability of Cd and Pb accumulations in 27 celery genotypes and 28 lettuce genotypes respectively, and to screen for Cd+Pb-PSC (pollution-safe cultivar , which edible parts accumulate certain pollutant at low enough level for safe consumption while grown in contam...
