Abstract: Phytic acid content in different parts of grain and rice quality traits were analyzed using thirteen different types of rice. The average phytic acid contents in rice bran, brown rice, glume, and milled rice were 48.51, 9.77, 140 and 0.91 mg/g, respectively. Phytic acid content in different parts of grain for different types of rice had a significant difference. The order of the phytic acid accumulation was as follows: rice bran>milled rice>glume. The phytic acid content in rice bran had a significantly positive correlation with those in brown rice and glume. The phytic acid contents in brown rice and rice bran both had a significantly negative correlation with the protein content in rice, and a significantly positive correlation with the 1000grain weight.

摘要: 选用13个不同类型的水稻品种,对其籽粒不同部位植酸含量品种间差异及与稻米主要品质性状间的相关性进行了分析。结果表明,供试13个水稻品种米糠、糙米、颖壳、精米的植酸含量平均值分别为48.51、9.77、1.40和0.91 mg/g,而且不同水稻品种间籽粒不同部位的植酸含量存在极显著差异。在籽粒中,米糠中植酸积累最多,其次是精米,颖壳最少。米糠中植酸含量与糙米和颖壳中植酸含量呈极显著正相关。糙米和米糠中植酸含量与稻米蛋白质含量均呈显著的负相关,与千粒重均呈显著正相关。
