研究了不同Cd水平(0、0.0 5、0.1、1、2、5、10和2 0μg mLCd)对营养栽培条件下番茄和玉米植株干物质、矿物质含量和植株耐性的影响。将番茄和玉米幼苗转移到营养液中，并加入Cd。应用Cd后3周评估生长差异。番茄的生长速度较快，但玉米的生长速度较慢。西红柿的生长速度下降得比玉米快。数据统计分析表明，番茄和玉米的干物质减少与矿物质含量之间存在显著的相关性。
The aim of this study was to determine the effect of increasing Cd levels (0, 0.05, 0.1, 1, 2,5,10 and 20 μg mL Cd) on plant dry matter, mineral content and plant tolerance of tomato and corn grown in nutrient culture. Tomato and corn seedlings were transferred to the nutrient solution and Cd was added. Growth differences were evaluated after 3 weeks of Cd applications. Growth sharply increased in tomato but more gradually in maize. Growth in tomato declined faster than in corn. Statistical analysis of data showed that there was a significant relationship between dry matter decrease and mineral content of tomato and corn.
