立足于我国水稻受镉污染的实际情况,研究镉胁迫对水稻生长发育的影响,并探讨伤流液镉含量与稻米镉含量之间的关系,为镉污染地区稻米安全生产提供数据支持和科学指导.采用营养液培育试验方法,选择中嘉早17和泰优390两个水稻品种,设置CK( 0 μg·L~(-1) ) 、Cd10( 10 μg·L~(-1) ) 、Cd50( 50 μg·L~(-1) ) 、Cd200( 200 μg·L~(-1) ) 、 Cd500( 500 μg·L~(-1) )和Cd1000( 1 000 μg·L~(-1) ) 6个Cd浓度处理,分析不同浓度镉胁迫对水稻生长发育的影响以及各部位镉含量与糙米镉含量的相关性.结果表明,与CK相比,ρ( Cd) ≤10 μg·L~(-1)处理对水稻生长有促进作用,但未达显著水平( P>0. 05) ,当...

The effects of cadmium (Cd) stress on growth of rice and the correlation between the Cd in bleeding sap and rice were studied by considering the actual situation of Cd pollution in rice in China, which will provide data support and scientific guidance for the safety of rice production in Cd-contaminated areas. Effects of different Cd concentrations (0, 10, 50, 200, 500 and 1 000 µg·L -1 ) on the growth of two rice varieties (Zhongjiazao No. 17 and Taiyou No. 390) and correlation between Cd content in different parts of rice and the brown rice...
