不同品种水稻糙米含镉量差异
Genotype Difference of Brown Rices in Cd Content.
【摘要】 采用盆栽土培法研究7个类型共46种水稻糙米含镉量的差异。结果表明,不同水稻品种糙米含镉量差异显著。在土壤含镉量为2 mg.kg-1时,46种水稻糙米含镉量变化范围为0.428~2.558 mg.kg-1。7种类型水稻糙米含镉量从高到低依次为特种稻、常规早籼稻、三系杂交晚稻、两系杂交晚稻、常规晚籼稻、常规粳稻、爪洼稻。
【Abstract】 A pot experiment was conducted to investigate cadmium(Cd)content in brown rices of 46 rice cultivars of 7 genotypes.Results show that the tested rice cultivars differed sharply between genotypes and vary from(0.428-2.558)(mg·kg-1) in Cd accumulation when the soil Cd content is 2 mg·kg-1.In terms of Cd content in grains,the 7 genotypes of rices are in the order of special rice>conventional early rice(Indianica sp.)>three-lined hybrid rice(Indianica sp.)>two-lined hybrid rice(Indianica sp.)>conventional late rice(Indianica sp.)>conventional Japonica rice>Javanica rice.
