摘要
采用盆栽土培法,研究了5个类型共89个水稻品种糙米含钙量的差异。结果表明,不同类型品种糙米含钙量差异显著。89个水稻品种糙米含钙量变化范围为44.5～245.5mg/kg。5种类型水稻糙米含钙量由高到低依次为:常规粳稻、杂交晚籼、常规晚籼、常规早籼、常规中籼。
A pot experiment was conducted to investigate cultivars of 5 genotypes. Results show that the tested rice calcium （Ca） content in brown rices of 89 rice cultivars differed sharply between genotypes and vary from 44.5～245.5mg/kgin Ca accumulation. In terms of Ca content in brown rice, the 5 genotypes of rice are in the order of conventional late onica rice〉hybrid late Indianica rice〉conventional late Indianica rice〉conventional early Indianica rice〉conventional medium Japonica rice.
