| 摘 要： | 研究结果表明,Cu在水稻植株各部位的富集情况是W根系>W茎叶>W颖壳>W米粒,相同部位不同品种之间的含Cu水平存在较大的差异。供试品种中米粒含铜水平最低的是“赣香糯”,其值为10.32 mg/kg,接近国家绿色、无公害大米标准的限值(10 mg/kg),最高的是“赣航晚2号”,其值为28.17 mg/kg。茎叶中的含铜水平与米粒中的含铜水平有很好的正相关,相关系数r=0.91。水稻根系具有较强富集Cu的能力,根系较发达、活力较强的品种其富集铜的能力较强。

| Abstract: | The study results show that the concentration order of Cu in different parts of the paddy plant was root>stem and leaf> chaff> grain ,the content of Cu in the same part of different obviously varieties varies.The lowest content of Cu is in "Ganxiangnuo",its value is 10.32 mg/kg,approaching the standard of Green and Innocuous Rice in China(10 mg/kg),the highest one is in" Ganhangwan 2 ",its value is 28.17 mg/kg.The Cu content in stem and that in grain have good positive correlation,whose correlation coefficient is r=0.91.The roots have stronger ability to enrich Cu.Varieties with stronger roots have stronger ability to enrich Cu. |
