中文摘要

Cabbage seedlings grown in vitro were exposed to
excess levels of heavy metals, including Cd, Mo, and Zn. High metal
levels affected plant growth at cotyledonary stage. Seedlings under
Cd, Mo, and Zn treatments could not produce root hairs and true
leaves. Under stress conditions, seedlings accumulated a higher
amount of anthocyanins in their cotyledons than those in the control.
The pigments isolated from Cd and Zn stressed seedling cotyledons
appeared as pink, while under Mo stress, was dark pink or purple.
Moreover, excess Mo stress increased antioxidant enzyme activities
of APX, CAT, SOD. These results suggest that, under excess Mo
stress, the induced antioxidant enzyme activity of cabbage seedlings
may function as a protective mechanism to shield the plants from
toxicity and exacerbated growth.
