Effects of Cd2+ on Seedling Growth,Chlorophyll Contents and Ultrastructures in Maize

doi:10.7668/hbnxb.2010.03.026

Abstract

Abstract: The effects of different concentrations of Cd²⁺ on seedling growth, chlorophyll contents and ultrastructures in maize were investigated using water culture method.The results indicated that the growth, chlorophyll contents and ultrastructures were not obviously affected at low concentration of Cd²⁺ ( 10^-6 mol/L).At 10^-5 mol/L Cd²⁺, the growth and chlorophyll contents decreased, swollen chloroplasts and irregular thylakoid were found in some leaves cells.In root cells, cell membrane systems were damaged significantly.At higher concentration of Cd²⁺ ( 10^-4 mol/L), the seedling growth was inhibited significantly.Some cellular organelles were damaged seriously, and even led to cell disintegration in root cells.The mechanism of Cd²⁺ toxicity was briefly discussed．

Key words: Cadmium, Maize, Chlorophyll, Ultrastructure
