作物籽实中Cd与Zn的交互作用及其机理的研究

ABSTRACTSInteraction Between Cd and Zn in Seeds of Crops and Its Mechanisms.

本文根据两个地区（沈阳张土污灌区和沈阳十里河地区）和两类作物（玉米和大豆）籽实中Ｃｄ，Ｚｎ含量的调查分析，论证了Ｃｄ－Ｚｎ之间的交互作用因作物种类而异。在玉米籽实中，Ｃｄ－Ｚｎ之间表现为相互抑制作用；而在大豆籽实中，Ｃｄ－Ｚｎ之间表现为协同作用。

AbstractThrough investigations in two areas (Zhangshi Sewage-Irrigation Area-apolluted area,and Shilihe Area-a normal area in Shenyang)and analog-ous analysis of two crops(maize and soybean),it is found that the inter-action between Cd and Zn varied with crops,There was an inter-inhibi-tcry mechanism between Cd and Zn in the seed of maize,while there wasa synergic mechanism between Cd and Zn in that of soybean.
