Abstract

The effects of Cd++ concentration increment in soil and/or in atmosphere, on germination, growth and alkaloid contents of Datura metel L. were investigated. We observed a significant reduction of growth following addition of Cd + + in soil. Minor effects on growth were evident when the plants were sprayed with CdCl2 solution (10mgCd++/1). Scanning electron microscope observation showed stomata widely open and conspicuous cuticular striations in the foliar epidermis of polluted plants. GLC analysis of extracts evidenced a significant variation in active principle content among plants undergoing different treatments. © 1989, Taylor & Francis Group, LLC. All rights reserved.
