| 1 | Effect of Exogenous Lanthanum on Accumulation of Cadmium and Its Chemical Form in Tomatoes显示文摘In the condition that soil is polluted by Cd(20 mg·L-1),two varieties of tomato(Lycopersicon esculintum Mill.)(plant high Cd-enriched variety(Yufen109)and plant low Cd-enriched variety(4641))treated with LaCl3 of different concentration(0,10 and 20mg·L-1)were determined for their effect on plant dry weight,anti-oxidase activity(CAT,SOD and POD),tomato fruit Cd chemical form and Cd accumulation.The results show that 10 mg?L-1LaCl3 can increase dry weight of plant at various positions and can reduce the concentration of Cd of different forms.Spraying with LaCl3(10,20 mg·L-1)can reduce Cd concentration in leaves,stems,roots and fruits of tomato plants with lowering rates of 13.7%-31.9%,9.5%-30.6%,10.8%-44.5%and 19.4%-37.0%,respectively.Suitable amount of lanthanum(10 mg·L-1 LaCl3)can increase yield of tomatoes,reduce Cd accumulation in the fruit.In the two tomato varieties,Lanthanum and Cadmium react interactively,expressing to be coexisting of both synergism and antagonistic. | XIE Wenwen XIONG Shijuan XU Weihong CHEN Rong ZHANG Jinzhong XIONG Zhiting | 2014 | Wuhan University Journal of Natural Sciences2014，19，3： | 0 |
