The environment is the main factor affecting variations in phytochemicals and antioxidant activity in rice. The objective of this study was to evaluate the stability of grain yield, phytochemicals and antioxidant capacity of six rice genotypes. Six rice genotypes were evaluated in a randomized complete block design with three replicates at three locations in Trat, Bangkok and Sakon Nakhon provinces in July-October 2019. Data on grain yield, yield components, total phenolic content, ferulic acid and antioxidant capacity were recorded. Grain yield was highest for crops grown in Bangkok, whereas antioxidant activity was highest for crops grown in Bangkok and Sakon Nakhon. Hom Nang Nual 1 and Mali Nil Boran had the highest grain yield. Riceberry had the highest grain yield in Trat; it also had high levels of total phenolic compounds, ferulic acid and antioxidant activity. Mali Nil Boran, Mali Nil Surin and Riceberry had the most stable total phenolic content, ferulic acid and antioxidant activity, respectively. Information on the levels and variability of phytochemicals in rice enables the selection of genotypes with high and stabile phytochemicals for production and rice breeding.
环境是影响水稻中植物化学物质和抗氧化活性变化的主要因素。本研究的目的是评估6个水稻基因型的籽粒产量、植物化学物质和抗氧化能力的稳定性。2019年7月至10月，在罗勇府、曼谷和呵叻府的三个地点，采用随机完全区组设计，对6个水稻基因型进行了三次重复试验。记录了籽粒产量、产量构成因素、总酚含量、阿魏酸和抗氧化能力的数据。曼谷种植的作物籽粒产量最高，而曼谷和呵叻府种植的作物抗氧化活性最高。Hom Nang Nual 1和Mali Nil Boran的籽粒产量最高。稻红米在罗勇府的籽粒产量最高；它还含有高水平的总酚化合物、阿魏酸和抗氧化活性。Mali Nil Boran、Mali Nil Surin和稻红米分别具有最稳定的总酚含量、阿魏酸和抗氧化活性。水稻中植物化学物质的含量和变异性信息有助于选择具有高且稳定植物化学物质的基因型用于生产和水稻育种。
