Influence of cadmium on the growth and metabolic contents of ambrosia maritima [electronic resource].

Includes references.

The effect of cadmium on the growth and some metabolic contents of Ambrosia maritima L. was studied. All morphological features of the plant were affected by the increase of Cd concentration from 0.0 to 3 mM. All measured growth parameters decreased by Cd treatment. The obtained results showed that the pigments contents of Ambrosia maritima leaves decreased by Cd increasing in the soil. Disaccharides as well as polysaccharides decreased with Cd treatments. In contrast to monosaccharides increased mainly due to the effect of Cd on enzymes activities. Protein nitrogen and total nitrogen were significantly decreased by the increase of Cd in the nutrient solution, but soluble nitrogen increase. Ambrosin and damsin contentsdecreased by Cd treatment. The ABA content of the shoot and root extract of Ambrosia maritima increased-by Cd treatment.
