以籼稻多系一号，特优175，威优77 三个品种的糙米为材料，分析了相同条件下生产的萌芽糙米及不同处理的萌芽糙米GABA（r-氨基丁酸）含量。试验结果表明：不同品种的萌芽糙米 GABA 含量差异显著，多系一号萌芽糙米 GABA 含量为244mg/kg，与特优 175，威优 77 比较差异达到显著水平；萌芽糙米 GABA 含量是糙米的5倍；糙米浸泡后催芽，在萌芽生长过程中 GABA 含量逐步提高，24h后达到最高值时开始下降；生长素 GA 对富集 GABA 有一定的促进作用，但烘干和晒干两种处理对萌芽糙米 GABA 含量没有影响
Abstract
γ-aminobutyric acid(GABA) content in Duoxi1, Teyou175 and Weiyou77 were anglicized from germinated brown rice by different treated methods. These showed that GABA content in different varieties were significantly distinct. Compared with Teyou175 and Weiyou77, Duoxi1 was significantly distinct, which was 244mg/kg. The content of GABA in germinated brown rice was over 5 times than un-germinated brown rice. While soaking and germinating, GABA content in germinated brown rice increased but decreased when it reached the top. Gibberellin can improve enrichment of GABA. And drying and insolation methods had not influenced on GABA content in germinated brown rice.
