[Cadmium effects on lipid metabolism of rape (Brassica napus L.)].

Treatment of rape seedlings with increasing CdCl2 concentrations in the culture medium resulted in a cadmium accumulation within plant tissues, which increased with external metal dose; such accumulation was more important in roots than in leaves. Biomass production was severely inhibited, even at low cadmium concentration. In leaves, quantities of chloroplastic lipids, monogalactosyldiacylglycerol (MGDG), digalactosyldiacylglycerol (DGDG), sulfolipids (SL) and phosphatidylglycerol (PG) decreased sharply under metallic treatment.

Effects of cadmium on the co-ordination of nitrogen and carbon metabolism in bean seedlings.

The effect of cadmium (Cd) was investigated on the in vitro activities of leaf and root enzymes involved in carbon (C) and nitrogen (N) metabolism of bean (Phaseolus vulgaris L. cv. Morgane).
