Cadmium-induced Functional and Ultrastructural Alterations in Roots of Two Transgenic Cotton Cultivars

摘要

@@ The toxic effect of cadmium (Cd) at increasing concentrations has been studied with special attention being given to root morphological and ultrastructural changes in two transgenic cotton cultivars viz.BR001 and GK30 and their wild relative cotton genotype viz.Coker 312.In comparison to their respective controls,low concentration (10 and 100 M) of Cd greatly stimulated seed germination,while it was inhibited by highest concentration of Cd (1000 M) in case of two transgenic cultivars.
