Comparison of adaptability to heavy metals among crop plants (part 2). Adaptability to zinc group metals-studies on the comparative plant nutrition

Journal Article:

Abstract

Eighteen crop species were grown in culture solution having graded levels of Zn, Cd and Hg, and the differences among species in response to these elements were discussed. As the average of all species tested, the metal content of the shoot is Ca > Mn > Zn > Cd > Hg, and the root-to-shoot content ratio is reversed at equivalent levels. These values increase with an increase in the level of respective ions in the culture solution. The metal concentration in the shoot among species does not change significantly with the level of that element. There is a positive correlation among species between Zn and Cd, but Hg shows a different trend. The tolerance to Zn is weak in many species of Gramineae and Curciferae, and strong Solanaceae and Umbelliferae. Many species of Gramineae are very tolerant to high levels of Zn or Cd due to a high excluding power of the roots, but possess a weak tolerance to high Hg levels. Egg-plant, soybean, and pea are susceptible to high levels of all three elements.
