The mechanisms for the differences among rice cultivars in Cd uptake and translocation There were significant differences in root oxidating abilities and soil redox potential between two typical rice cultivars, Shan you 63 and Wu yun jing 7, that are greatly different in Cd uptake from soil. The root oxidating abilities and soil Eh were accordant with Cd uptake for the cultivars. The difference between the two cultivars in Fe concentrations of root iron plaque was also significant. The cultivar with higher Fe concentrations in root iron plaque absorbed less Cd from soil.
四、水稻不同品种对镉吸收及分配存在差异的生理机理对土壤中Cd吸收能力差异很大的水稻不同品种间,根系氧化力和土壤氧化还原电位有显著差异,品种的根系氧化力和土壤氧化还原电位与该品种对Cd的吸收能力间有很好的一致性;水稻不同品种间,根表铁氧化膜的含铁量有显著差异,根表铁氧化膜含铁量高的品种,对土壤中Cd的吸收能力低;盆栽水分腾发量高及根系伤流液Cd浓度高的品种,吸收积累Cd的能力强。

In the process of laboratory study, oxycodone was prepared by oxidating thebaine at 6,14-position under oxydol, hydrodeoxidizing 7,8-position double bond and 14-position ether under palladium catalyst. Furthermore, N-methyl of oxycodone was isolated byα-chloro-ethyl chloroformate under anhydrous condition and protection of 14-position hydroxyl to obtain noroxycodone, which was further converted into methylnaltrexone by N-alkylation in presence of cyclopropyl bromomethane, then by isolating 3-position methyl of methylnaltrexone under boron tribromide, becoming hydrochloride to prepare target compound, natrexone hydrochloride.
实验室工艺方面,本文首先用双氧水氧化蒂巴因的6-位和14-位、在钯炭催化下加氢还原7-8位双键和14-位醚合成羟考酮,然后提出并优化了在无水和14-位保护的情况下,用氯甲酸-α-氯乙酯脱去羟考酮的N-位甲基合成去甲羟考酮,再用环丙甲基溴将去甲羟考酮的N-位烷基化合成甲基纳曲酮,最后采用三溴化硼脱去甲基纳曲酮的3-位甲基和成盐酸盐合成盐酸纳曲酮。
