摘要：

To reduce the influx of cadmium (Cd), a toxic heavy metal, into the human food chain through vegetable intake, a pot experiment for the selection of a pollution-safe cultivar (PSC) of water spinach (lpomoea aquatica Forsk.) was carried out. The experiment with 30 tested cultivars revealed that the maximum differences in Cd concentration between the cultivars containing the highest and the lowest Cd were 3.0-3.9-fold under low-Cd treatment (soil Cd = 0.593 mg kg-1), 2.7-3.5-fold under middle-Cd treatment (soil Cd = 1.091 mg kg-1), and 2.6-2.7-fo...
