Abstract:
Three Brassica chinensis var.chinensis ‘Akita Shanghai vegetable’,‘Youdong vegetable’，‘Aijiao black leaf vegetable’were used as test materials，the effect of different concentration of Cd on seed germination，and under the hydroponic conditions，physiological and biochemical，and green vegetables Cd accumulation were studied.The results showed that，the effect of Cd on seed germination was that，low concentration would promote growth while high might inhibit the growth of the seed.When Cd concentration of 5.0 mg/L，three varieties of germination rate reached the highest，were 91.30%，90.00% and 89.30% respectively.When it was 20.0 mg/L，seed germination rate of ‘Akita Shanghai vegetable’,‘Youdong vegetable’ tended to be lower significantly(P<0.05).When it was 50.0 mg/L，seed germination rate of ‘Aijiao black leaf vegetable’ tended to be lower significantly (P<0.05).When it was more than 1.0 mg/L，the green biomass might be inhibited significantly (P<0.05).With the increase of Cd concentration，the Cd accumulation ability of different varieties of vegetables increased.Besides，When Cd concentration more than 1.0 mg/L，the ‘Akita Shanghai vegetable’ Cd accumulation ability was higher than control，and achieved significant difference(P<0.05).With the increasing of the Cd concentration，Cd accumulation of three vegetables increased.While the Cd accumulation ability were significantly different，that was，‘Akita Shanghai vegetable’ Cd concentration was significantly lower than the other two varieties.
